covid-19 found in wildlife in 24 U.S. states

It was reported on the 30th that a team of scientists in the United States recently confirmed that the new coronavirus has been found in wild animals in at least 24 states in the United States. Researchers are concerned that the virus may evolve in animal populations, producing dangerous virus mutants that could be passed back to humans.

Virus mutants may be passed back to humans

A team of scientists in the United States recently tested wild animals such as bears, deer and wolves for the corona virus in a remote Native American reserve in northern Minnesota. They are trying to figure out how, how and where wild animals spread the virus. Now, scientists have found the new coronavirus in wildlife in at least 24 states, including Minnesota.

Scientists worry that the virus could evolve in animal populations, producing dangerous virus mutants that could be passed back to humans and spread between humans. “If the virus can find its place in a wild animal host, there is always a threat of the virus re-spreading into the human population,” said University of Minnesota researcher Matthew Arriotta.

Fish and wildlife biologist Isaac said he expects the risk to become higher as spring arrives, bears wake from hibernation and deer and wolves roam different areas.

looking for mutants

The close contact between humans and animals allows the virus to overcome inherent barriers to transmission between species. To infect any organism, a virus must enter its cells, which is not easy. David O’Connor, a virologist at the University of Wisconsin-Madison, likens the process to opening a “lock” with the “key” of the virus’s spike protein. “Different species have different locks, some of which cannot be opened by a key,” O’Connor said. But there are also “locks” that are similar enough that viruses can enter animal cells and replicate. It can also mutate randomly and find a key that fits the human “lock”. Scientists believe this allows it to be passed back to humans through close contact with live animals. While this is rare, it takes just one person to bring a mutated virus into the human realm.

Some believe the highly mutated Omicron variant came from animals, not from immunocompromised humans, as many believe. One of them is Mark Johnson, a virologist at the University of Missouri. Johnson and his colleagues found bizarre lineages of coronaviruses in New York City sewage with mutations rare elsewhere that he thinks came from animals, possibly rodents.

How to stop it?

Scientists are most concerned that current or future variants might establish and multiply widely in the main species. “It’s possible that the virus has been circulating in multiple animals,” said Suresh Kuchipudi, a virology expert at Penn State University. If left unmonitored, the virus could catch people “completely off guard,” he said. “.

Experts say the only way to stop the virus from spreading back and forth between animals and humans is to address major issues such as habitat destruction and illegal wildlife sales. “We’re encroaching on animal habitat in unprecedented ways,” Arliota said. “Unfortunately, I think the spread of events from wildlife to humans is increasing in frequency and scope.”

In response to the threat, the United Nations’ Food and Agriculture Organization, the World Organization for Animal Health and the World Health Organization are urging countries to prioritize animal surveillance of the coronavirus.

Indonesia prepares to turn Covid-19 pandemic into endemic

On the 28th, Indonesian Health Minister Budi Gunadi Sadikin said at an online press conference that the new crown pneumonia epidemic in Indonesia is under control, and Indonesia is ready to turn the new crown epidemic into an endemic epidemic.

Minister Budi said, “Thank God, Indonesia is ready to turn the Covid-19 pandemic into an endemic”. Several indicators show that the situation of the new crown in Indonesia has improved, including a decline in the number of confirmed cases and deaths in a single day across the country. In addition, the bed occupancy rate of COVID-19 hospitals across the country is already lower than 10%, and the COVID-19 positive rate is also lower than 5%, showing that Indonesia is well prepared to respond to the epidemic.

Minister Budi also commended the dedication and hard work of all health workers who are at the forefront of the fight against Covid-19. “The contribution of health workers in all regions has been remarkable,” he said.

On the other hand, in response to the termination of former Health Minister Terawan Agus Putranto as a member of the Indonesian Institute of Doctors (IDI), Minister Budi responded that he hoped the issue would be resolved soon. Coordination among health workers is important to address health issues.

Budi noted that the Ministry of Health will initiate and assist the mediation process between the Indonesian Doctors Association and its members to have good communication and create a favorable situation. In addition, he said, Indonesia still has some “homework” in the health sector, including alleviating stunting, dealing with infectious diseases such as malaria, and minimizing diseases such as diabetes and high blood pressure.

Congress adopts ‘ostrich policy’ as America is heading for the next pandemic

The American independent news website “Truthout” issued an article on the 27th that although the new crown epidemic is still ongoing, the US Congress has determined that the epidemic has ended. This “ostrich policy” of burying its head in the sand is pushing America into the next pandemic.

The article pointed out that the number of new crown cases across the United States has declined, mask orders have been widely relaxed, telecommuting has continued to decline, and almost all members of Congress are pushing for the repeal of masks on planes and other public transportation regulations. But with the spread of the Omicron virus subspecies BA2, Fauci, director of the National Institute of Allergy and Infectious Diseases, expects that the number of new crown cases in the United States will increase.

In this case, Congress vetoes plans to increase government spending on the pandemic, especially for the poor and the uninsured, with potentially disastrous results. With Republicans, Democrats, and even some public health officials insisting on putting the outbreak behind them and allowing people’s lives to return to “normal,” it remains to be seen whether the U.S. has escaped the effects of the outbreak.

Some in the U.S. are pushing for “living with the virus,” but they tend to ignore the risks to those who are immunocompromised and ineligible for vaccinations. For the millions of Americans with chronic illnesses, disabilities or other health problems who may not meet the CDC’s definition of immunocompromised, they are at higher risk. Also, with the emergency appropriations bill stuck in Congress, the U.S. will no longer be able to pay for coronavirus testing and treatment for the uninsured. In this case, uninsured people face imminent disaster if they contract Covid-19 or need a booster shot. Some uninsured people may forgo opportunities for timely medical care due to concerns about medical bills, further contributing to the spread of the virus in the community.

The disaster doesn’t stop there. U.S. government officials have said that if Congress does not approve funding for the new crown epidemic, the United States will not be able to provide enough vaccine boosters and related treatments to the population. All in all, this means that the U.S. is not ready for future variants of the new coronavirus, different types of epidemics, or even the current state of the spread of the epidemic in the United States.

As “Atlantic Monthly” contributor Ed Yong said, the current epidemic prevention measures in the United States “are no longer sufficient” to deal with the task at hand. “These measures need to be strengthened, not weakened further. The premise of abandoning the epidemic prevention measures is that the United States does not need to deal with another large surge in new crown cases.” However, he added that the United States is now heading for the next pandemic.

Instead of passing agencies and enduring programs to address current, short-term and long-term needs, Congress has buried its head in the sand. The current reduction of funds for the epidemic is precisely the “greed for small gains and big losses”. In a medical maxim, an ounce of prevention is worth a pound of cure. Instead of using this period of relatively low levels of community transmission to bolster defenses against the virus, Congress is rolling the dice and betting that the worst of the pandemic is over.

The pandemic has shown that public spending at the federal level in the United States can generate enormous public benefits. Unfortunately, Congress appears to be back in austerity-based hawkish thinking. That means U.S. public health will be at risk in the months ahead, let alone decades into the future.

What is the purpose of viruses?

From the 15th century to the mid-19th century, the virus was the patron saint of the African continent. In the past 400 years, European colonists only occupied 10.8% of the land in Africa, and only occupied some strongholds along the coast of Africa and offshore islands.

The climate in Africa is dominated by tropical rain forests and tropical deserts. It is not only a paradise for wild animals but also a paradise for microorganisms.

In terms of known viruses (smallpox, Lassa, dengue, HIV, Ebola, etc.), almost all of the world’s top viruses come from Africa.

The virus is the “invisible killer” of the American continent.

When Columbus discovered the Americas in 1492, there were about 30 million natives in the Americas at this time.

By the end of the 16th century, there were only 1 million Native Americans left!

Because the viruses carried by European colonists (mainly smallpox) brought disaster to the Native Americans.

500 years later, in the First World War (July 28, 1914 – November 11, 1918), in March 1918, American soldiers went to the European front. cold”.

Influenza swept across the European continent and the world at an alarming rate.

In the US, 548,000 people died from the flu. In the UK, 215,000 people died from the flu. In France, 166,000 people died from the flu. In Germany, 225,000 people died from the flu. Because of the flu, the warring sides were forced to end the war.

The new coronavirus is still affecting the world. Why can’t we eradicate the virus?

Because of the stagnation of physics, our understanding of the microscopic world is very pale. If we can’t make breakthroughs in the understanding of the microscopic world, we may never be able to eliminate the virus in the human body.

Therefore, we must have awe of nature, and we must learn to live in harmony with nature and wild animals. If this harmonious relationship is broken, there will be severe punishment.

Three World Plague Pandemics in Human History

Speaking of plagues, many people think of various infectious diseases in history, such as smallpox.

It is understood that about 60% of the world’s population has suffered from the threat of smallpox, and a quarter of the infected people lost their lives, and the survivors will inevitably leave various “sequelae”.

Even the ancient emperors were not immune to the infection of smallpox, such as Emperor Kangxi, Emperor Shunzhi, and Emperor Tongzhi we mentioned earlier. Mazi, who died directly from smallpox. The catastrophic history that smallpox brought to human beings may be much longer than the plague. It is said that the scars left by smallpox were found on the mummies of ancient Egyptian pharaohs.

Back in ancient times, smallpox was even used as a secret weapon, and the Aztec empire was wiped out by infection and epidemics.

In addition to smallpox, the plague is also one of the most serious plagues in human history.

01 History of the Black Death
In 1947, the French writer Albert Camus wrote a novel about the plague disaster. Today, this novel is often mentioned by everyone for the same reason, that is, the novel depicts the plague under the plague. All kinds of life are too similar to the society we are facing today under the epidemic.

writer albert camus

About the plague, everyone is well-known, it should be another name, the Black Death. Back in the Middle Ages, the epidemic killed more than 25 million people across Europe. From 1348 to the third year, this serious epidemic centered on Europe gradually spread to many parts of the world, and caused the death of nearly half of the people in Europe. After that, this infectious disease was prevalent in Europe for nearly two hundred years.

This is enough to see how much harm the plague caused to humans.

Of course, not only in Europe, but also in my country, the plague has caused heavy damage to the people. There is a poem written by Shi Daonan, a poet in Zhaozhou: “The rat died in the east, and the rat died in the west. When people see dead rats, they are like tigers. When the rats die within a few days, people die like tearing down a block.

People die during the day, don’t ask the number, the sun is bleak and cloudy, three people walk, before ten steps, two people die suddenly and cross the road… “Dead Rat Walk”. “

This summary is also enough to see how scared people at that time were when they saw mice, especially dead mice.

Because of the death caused by the plague, it is enough to make people panic and retreat.

In 2011, a group of scientists came to London and openly dug up a cemetery where the dead were buried between 1348 and 1351, took away the unrotting teeth of the deceased buried in the ground, and used modern technology in the laboratory. DNA sequence comparisons of the strains were performed.

And the deceased whose cemetery was opened is the patient who died during the Black Death pandemic. The results of the study, however, found that the DNA of the 600-year-old strain obtained from the dead in the cemetery was different from the DNA of all known strains.

For this reason, experts believe that the plague bacillus that year died out at a certain historical stage in history. It is not difficult to understand why after the Black Death swept across Europe and caused heavy damage to human beings, there has never been such a strong and severe plague disease.

However, how did the plague spread and how did it have such a huge impact on humans?

Regarding this issue, many people’s understanding is that it was passed from mice to humans. However, it is said that the plague is not directly transmitted to humans by rats, and the rats are not the source of the plague, but the marmot is the real source of the plague.

Marmots, also called marmots, are rodents that live mostly in burrows. The human plague in the foci of marmots is usually infected by direct contact with infected animals, especially when hunting, stripping and eating marmots.

02 Epidemic history of plague
Plague is an ancient infectious disease. There have been three world plague pandemics in human history, and these three pandemics have had a very serious impact on the development of human civilization and society.

The first pandemic occurred in the 6th century AD, about 527 to 565. This time, the plague pandemic spread to almost all the famous countries in the world, and the death toll was about (up to) 100 million people. The plague pandemic this time directly led to the decline of the Eastern Roman Empire.

The second pandemic occurred in the 14th century AD, probably between 1347 and 1350. Its scope is also very wide, covering Europe and Asia and the north coast of Africa, and Europe is the most extensive. This epidemic is known as the Black Death in Europe.

The third pandemic occurred at the end of the 19th century and until the middle of the 20th century, it affected more than 60 countries and regions, including Asia, Europe, America, Africa and other places.

As a deadly infectious disease, plague has also been used as a “biological weapon”. Back then, when one after another corpses fell from the sky, the residents of the port city of Kaffa on the Black Sea never imagined that the disaster for them and the whole of Europe would begin.

In 1347, the city of Kafa (now the Ukrainian city of Feodosia) could not be conquered for a long time. The Mongols, who were used to using biological warfare as a weapon, decided to throw the corpses infected with the plague (Black Death) into the city as a way to use them as a weapon. plague to overwhelm the enemy. As a result, just as the Mongols wished, the plague quickly spread in the city of Kafa, causing a large number of deaths.

After that, the escaped people brought the virus to Italy, and finally to Spain, France, the United Kingdom and other places. Eventually, the plague swept across Europe, killing more than 20 million people and reducing the European population by more than one-third.

Plague, war and famine are known as the “three major killers” of tragedies in human history. They not only brought panic and chaos to society and the country, but also brought catastrophic blows to human beings, causing death or even extinction. .

03 The disaster brought to mankind by the plague
Generally speaking, the epidemic of infectious diseases is generally “beginning and ending”. It will be affected by factors such as population in different regions, population density, environmental climate, etc. In a long or short period of time, it will disappear after a period of epidemic. . However, the damage caused by the plague to human beings cannot be cured by time.

As early as in ancient times, plagues caused far more harm to people than in modern times. In that era when the medical level was still relatively backward, once infected with the plague, the possibility of its survival was very small. Because there is no cure, the sick person is almost equivalent to being sentenced to death, waiting for death to come.

“Records of the Three Kingdoms Wu Shu – Master Wu Biography” records: “The public (Cao Cao) burned the rest of the ships to retire. The soldiers were famined and most of the dead were killed.” It can be seen that the harm caused by the plague to people at that time was how much. In 209 AD, “The Chronicles of the Three Kingdoms Wei Shu Wu Di Ji” also recorded: “Since it has been a while, the army has been marching, or encountering epidemics. The officials and officials died and did not return, the family was grieving, and the people were displaced.”

Here, it directly highlights the great harm caused by the plague to human beings.

The plague brought not only immediate death to human beings, but also endless pain and chaos.

Back then, Europeans were devastated by the Black Death, suffering unbearably. Because the death toll was too fast and too many, many could not be accurately counted. After the outbreak of the Black Death in Europe, many people went to the church to pray, but people found that even praying to God was of no avail.

For this reason, people have turned their attention to cats and dogs. The traditional idea in Europe is that once bad things happen, the pets in the home are very likely to become the spokespersons of the devil, and for this reason, people will attack these cats and dogs and kill them. However, when the cats and dogs were almost killed, the Black Death still did not disappear.

Later, people quickly found another “disease” reason, that is, it was believed that a Jewish woman brought the Black Death from other places, so for a long time at that time, people carried out a A large-scale persecution led to the killing of countless Jews.

In China, the deaths caused by the plague are also numerous. In 1353, a great plague occurred in Huangzhou and Raozhou. At the end of the year, there was a big epidemic on Datong Road, and “most of the dead”. In the spring of 1356, a great epidemic spread in Henan. In 1357, the Great Epidemic of Changzhou.

In June 1358, Fenzhou suffered a great epidemic. “The people of the two rivers were brought into the capital by soldiers, young and old, and the dead were bedridden due to famine.” By April 1360, more than 200,000 people had been buried in the capital. Such fearful and devastating infectious diseases are not common in the world.

Politicians from many countries are infected with the new crown virus

New cases increased in the Western Pacific Region and decreased in the Eastern Mediterranean Region, the African Region, the South-East Asia Region and the Americas Region. The five countries that reported the most cases last week were South Korea, Vietnam, Germany, France and Australia.

Americas: Former U.S. Secretary of State infected with the new crown

Former US Secretary of State and former “First Lady” Hillary Clinton announced on the 22nd local time that her new crown test result was positive.

Hillary Clinton posted on social media that day that she was “feeling well” and had “mild cold symptoms.” She also expressed gratitude for the protection provided by the vaccine and urged those who have not yet been vaccinated to get the vaccine and booster shots as soon as possible.

She also said that her husband, former US President Bill Clinton, tested negative for the new crown. He will stay home until Hillary Clinton recovers.

On the same day, White House press secretary Psaki also issued a statement saying that she tested positive for the new coronavirus nucleic acid that day and would no longer travel to Europe with US President Biden. This is the second time Psaki has been diagnosed with the new crown.

Psaki said in a statement that Biden’s new crown test result was negative that day. She had two “social distance” meetings with Biden on the 21st. According to the CDC’s epidemic prevention guidelines, Biden is not a close contact.

On March 22, local time, according to data from the U.S. Centers for Disease Control and Prevention, as of March 19, cases related to the BA.2 evolutionary branch of the Omicron variant accounted for 34.9% of new cases in the United States. According to the data, the Northeast region of the United States has the highest number of related cases, with about 51.8% in the New York metropolitan area and 55% in the New England region.

Europe: The German president and his wife, the Norwegian king are infected with the new crown

On the 22nd local time, German Federal President Steinmeier and his wife Budenbender were confirmed to be infected with the new crown virus. According to a spokesman for the President’s Office, Steinmeier and Budenbender both tested positive for the rapid test and nucleic acid test results that day, and the two immediately entered a state of home isolation. “Their symptoms are currently mild,” the spokesman said. Close contacts of the two have also been notified.

According to Reuters, the Norwegian Royal Palace issued a statement on the 22nd local time that King Harald V of Norway had tested positive for the new crown virus. The palace said the 85-year-old king had mild symptoms of the virus.

The Spanish Public Health Commission approved a new strategy for monitoring cases of new crown infections on the 22nd, which stipulates that cases with positive results for the new crown virus but no symptoms or mild symptoms do not need to be quarantined. This measure will be implemented from March 28 local time. effective from today.

On the 22nd local time, the Swiss federal government held the country’s last press conference on new coronary pneumonia. Many Swiss have been infected with the new coronavirus in recent weeks, with an estimated 100,000 new infections a day, according to Patrick Mattis, a crisis management officer at the Swiss Federal Office of Public Health.

About 10% of the Swiss population currently has the virus, Mattis said. While the COVID-19 pandemic is not over yet, Switzerland will disband its epidemic expert group and expects to lift the final restrictions from April.

Asia: The cumulative number of confirmed cases in South Korea exceeds 10 million

According to statistics from the South Korean health department, as of 00:00 on the 23rd local time, in the past 24 hours, the country reported 490,881 new confirmed cases of the new crown. It was the second-highest number of new confirmed cases in a single day since its emergence in South Korea. The cumulative number of confirmed cases in South Korea also exceeded 10 million, reaching 10,427,247, which is equivalent to 1 in 5 Koreans infected with the new coronavirus.

Since South Korea reported its first confirmed case at the end of January 2020, after more than two years, the cumulative number of confirmed cases in South Korea exceeded one million on February 6, 2022. In the past 40 days, the cumulative number of confirmed cases has grown to over 10 million. Among them, over 90% of them will come from the first three months of 2022.

The recent rapid deterioration of the epidemic in South Korea has also made South Korea the country with the largest increase in the number of confirmed cases in the world. In the face of the severe epidemic prevention situation, the South Korean health department said that it is still too early to judge whether the epidemic has reached its peak, and relevant epidemic prevention measures will continue.

The Malaysian health department reported on the 22nd that there were 17,828 new confirmed cases of new coronary pneumonia in the country on the 21st, and the number of cases remained below 20,000 for the second consecutive day after the 20th.

How to reduce weight?

Every fat people want to be able to thin down, so how can scientific weight loss, reduce the body fat? We should keep in mind the six-word principle: keep your mouth shut and keep your feet open.

Alleged: 3 minutes eat 7 minutes to go through, have food union only fitness, the quantity of heat that raises the body gap, your ability is more scientific, healthy ground thin come down.

A lot of people will rebound, weight gain, the main reason or in the process of weight loss to choose the wrong method, the method is too extreme, such as: extreme dieting, weight loss too fast, lead to muscle loss, easy fat physique will patronize you.

Want to scientific weight loss, reduce the chance of weight loss, a few weight loss methods to learn:

  1. Dieting doesn’t mean dieting too much.

During weight loss, you can control your diet by avoiding junk food and eating vegetables that are high in fiber and low in calories. However, the daily intake of calories should not be less than 1200 kcal, otherwise the body will fall into famine, hypoglycemia, fatigue, amenorrhea, anorexia and other health problems, weight loss is easy to regain.

Three meals should be regular, maintain a diversified diet, meat choose low-fat chicken breast, fish, staple food can eat less rice, noodles, appropriate to eat some coarse grains, only balanced intake of carbon, fat, protein, in order to maintain the body metabolism level.

Eat eight points full, eat slowly

Usually do not eat to stretch yourself, eat slowly, because it takes time for the body to release to receive the signal of satiation, if you eat several bowls of rice in a few minutes, it is easy to overeat without realizing it, but also easy to expand the stomach capacity, resulting in body weight.

We should develop healthy eating habits, usually eat slowly, a meal for 20 minutes, eat eight full rice to stop chopsticks, so as to maintain a strong stomach power, control stomach capacity, to achieve the purpose of weight loss.

  1. Diversify your exercise

Fitness exercise can improve activity metabolism, accelerate the decomposition of fat, therefore, during weight loss, we should let ourselves move, so that the body will be better.

However, it should be noted that the exercise should not be too simple, because the body will gradually adapt to the same exercise mode for a long time, and the efficiency of fat burning will be much worse than before.

We can choose jogging, square dancing and other sports at the beginning. After 1-2 months, we will change to other sports, such as rope skipping, jumping jacks, swimming and so on, so as to improve the efficiency of fat burning. Each exercise time should not be less than half an hour, so that fat burning efficiency can be guaranteed.

Speaking of weight loss, xiaobian once also deeply troubled, later in the recommendation of a friend began to break the diet to lose weight, plus daily exercise, just from 140 pounds to 90 pounds! However, every method of weight loss, not suitable for everyone, if you insist on light food, but weight gain, that this method is not suitable for you.

It’s better to give up than to eat too much and feel miserable. Human instinct is to escape pain, so, our subconscious will resist us to reduce weight very much, the effect of reducing weight is not good naturally.

The idea is not to go completely off food, but to eat normally five days a week and then go on a low-calorie diet for two days.

Strictly speaking, a day of fasting is a day when you just skip lunch. You can have breakfast and dinner and still have a delicious meal.

If you don’t know how to start dieting, I’d like to recommend two professional guidelines for dieting: Dieting two days a Week and Dieting without Losing Weight.

No matter you are office workers, students, or the weight of large base group, small base group, can find their own light break food program, let the body open the “burning fat” fast thin mode, healthy, easy, effective thin down!

Intimate guidance, lose weight faster
Weight loss do not blindly grope, not only easy to rebound, unscientific operation is also easy to hurt the body.

And this book is like a professional teacher, providing you with a thoughtful diet of light food, so that you can get the nutrients you need, but also control the body fat, avoid eating more weight.

Male and female categories, so that they and their families can be healthy and thin
No matter you are a man or a woman, if you want to slim down and make your body healthier by fasting, you can find a solution suitable for you from this book.

The dishes are also very simple, with simple steps to match the big picture of food, and even the kitchen novice can easily get started.

If you want to take the family together to lose weight, or to help the family conditioning physique, then this book is absolutely an excellent family fat reduction health books.

Don’t like to eat salads all the time? Try enzymes and yogurt to keep your weight down while satisfying your picky mouth.

You don’t have to lose weight fast to join a light eating program, just be willing to start making changes for yourself. Transform body function, reshape eating habits, accelerate metabolism, and live a healthy life from the inside out.

Spring is the good season that reduce weight, be absent now reduce weight, the skirt of summer and cool and refreshing followed you without a chance! And weight loss is also to choose the right method, or it is a vain effort!

Make the right healthy fat loss choices now, click the link below to buy and start a new healthy life!

Israel has detected an unknown novel Coronavirus variant, suspected of being caused by recombination of two omicron variants

On 16 March, the Ministry of Health in Israel announced that two new and previously unknown novel Coronavirus variants had been detected in the country.
The cases were detected by polymerase chain reaction (PCR) tests on two passengers returning to Israel after they arrived at Ben Gurion International Airport. The Shamir Medical Center in Israel, which conducted the PCR tests, said that based on the test data, the variant was suspected to be a recombination of the ba.1 and BA.2 strains of omicron, with the characteristic variation of both strains. Relevant samples have been sent to the Israeli Ministry of Health and the Central Virus Laboratory for deep sequencing.
Those infected with the variant reportedly show symptoms such as low-grade fever, muscle pain and headaches, but do not require special treatment.
Nahman Ashe, director-general of Israel’s Health Ministry, told the media that the strain probably originated in Israel and the cases were likely infected when they left the country. Recombination of viruses is a common phenomenon and can occur when human cells are infected with two viruses at the same time, with the viruses exchanging genetic material as they multiply to produce a new virus, according to Salman Zaka, Israel’s chief COVID-19 official. At this stage, we are not concerned that it will lead to a serious situation.
According to a pre-print article published on 22 February by the National Serum Institute, part of the Danish Ministry of Health, it is possible for humans to be reinfected with the BA.1 variant of the Omicron strain for a short period of time, but this is rare. From the emergence of the Omicron strain in late November 2021 to February 2022, a total of approximately 2 million people in Denmark were infected with the strain, of which 67 were found to be infected with the BA.1 and ba.2 variants within 20-60 days of each other.
Earlier, on GitHub, a researcher reported on the GISAID International Novel Coronavirus Genome database that it had found up to 267 genome samples suspected to be recombinant variants of the Omicron ba.1 and Ba.2 strains in the UK and Ireland, and published the data on the variation. As reported by Forbes.com, suspected recombinant variants of the Omicron strain BA.1 and Ba.3 have been detected in the GISAID International Novel Coronavirus genome database, but the numbers are small, with only four samples detected in South Africa and one each in the United States and Puerto Rico as of 16 March.
It is unclear whether the unknown variant found in Israel is related to the related variant described on GitHub.

Tonga Prime Minister Sovaleni has been confirmed as infected with novel Coronavirus

Tonga’s Prime Minister Shosi Sovaleni has been confirmed to have contracted the Novel Coronavirus infection and is in quarantine at home, tongan media reported On Wednesday.

“The novel coronavirus test results were positive and the symptoms are mild,” sovaleni said in a statement issued by the Tongan Prime Minister’s office on Tuesday. “Sovaleni and his family members will be quarantined at home for 13 days in accordance with health regulations.” The prime minister’s office said Sovaleni had previously been fully vaccinated against COVID-19 and a booster vaccine. He will continue to exercise his powers as prime minister during quarantine.

In her statement, Sovalene called on Tongans to continue their vaccinations and remain vigilant for the Novel Coronavirus pandemic and to comply with quarantine measures.

In Tonga, an island nation in the South Pacific with a population of more than 100,000, about 89 percent of the target population is fully vaccinated.

The UK has become the first country to “live with the virus” and its death rate is lower than that of influenza

Novel coronavirus is now less deadly than flu in the UK, thanks to its mildness and high immunisation rate, according to the latest official figures. Before the outbreak of the highly contagious strain, the virus had a mortality rate of about 0.2 percent, according to the data. But it has since shown a sharp decline and is now stable at around 0.035% (Figure 1), the same level as influenza (blue area of Figure 1).

Mortality rates in Britain have fallen steadily, largely because of vaccination and the development of antibodies in infected people. In the context of the rapid global push to vaccinate the entire population against COVID-19, the UK government had already introduced booster shots for people aged over 50 before the omicron strain spread last year, which greatly increased the rate of antibody against COVID-19 in the UK.

In January 2021, when the government first launched the vaccination campaign, the DEATH rate in the UK was just over 1%. In July 2021, the figure fell to 0.1%; During the transmission of the Omicron variant, the mortality rate decreased approximately threefold, significantly dropping to 0.035% (Figure 2). According to the latest figures, 35 deaths per 100,000 omicron infections, compared with 40 deaths for the same number of influenza infections; Even among those 80 and older, the death rate from omicron infection dropped to 0.05%, also lower than the flu fatality rate in the same age group.

Statistical analysis shows that this is the first time since the outbreak, and the death rate of COVID-19 is “relatively lower than that of seasonal flu”, achieving a stage victory of “co-existence with COVID-19”. Previously, due to the dual impact of Brexit and the outbreak of COVID-19, the UK’s economic development suffered a heavy blow. In 2020, the UK’s economy shrank by 11.5%, making it the most severely affected economy among developed countries. It is urgent to change the status quo and put the economic development back on track. On this occasion, Britain has tried to return to normal life. The UK government is expected to lift all quarantine restrictions against COVID-19 in the coming days, including PLF and testing requirements for unvaccinated travellers. The UK is expected to take advantage of Easter to boost flight bookings and reap a wave of economic benefits from tourism.

But while optimistic, scientists warn that this positive trend could be reversed at any time in the future with the emergence of a new virus variant.
