Novel Coronavirus was detected in wastewater from Paris, France

On August 8, it was reported that novel Coronavirus showed signs of rebirth in a sample of wastewater from Paris recently tested by researchers.
At the same time, novel Coronavirus infection rates have increased in some provinces in ile-de-France region, where Paris is located, but it is too early to judge a rebound from the epidemic.

According to the report, the researchers tested 12 samples of wastewater collected from June 22-25, among which 6 samples tested positive for traces of novel Coronavirus.
The researchers repeated the tests a week later, and the results were the same.

In mid-to-late April, a trace of novel Coronavirus was found in a non-drinking water system used to clean streets and water parks in Paris. Traces of novel Coronavirus were found in 4 of the 27 sampling points. Subsequently, the Municipal government of Paris shut down part of the water supply system.
Novel Coronavirus was not detected in the sampling conducted in mid-May, which is basically consistent with the trend of epidemic situation in France.

After the coVID-19 outbreak in France, local researchers continuously monitored the content of novel Coronavirus in the wastewater. By analyzing the samples collected from March 5 to April 23, the researchers found that the level of novel Coronavirus detected in the wastewater was correlated with the number of confirmed coVID-19 cases.

In a bulletin issued on 7 July, the French Academy of Medical Sciences recommended systematic monitoring of wastewater to better understand novel Coronavirus transmission.
