Scientists in the United States identify the spread of coronavirus by analyzing wastewater

This method helps to detect early signals of the COVID-19 outbreak, WSJ notes.

American experts are increasingly using a method that allows them to detect the spread of a new coronavirus in the country’s cities by studying wastewater. This is stated in an article by The Wall Street Journal.

As noted in the article, the Federal Centers for Disease Control and Prevention (CDC) The US has allocated about $ 33 million to 31 research centers for “testing wastewater in the coming months.” “This method involves taking water samples from the city sewer system and their subsequent examination for the presence of the virus. This allows you to get an idea of the extent of the spread of infection, as well as to understand whether the number of infected people is growing or decreasing.

The publication says that this method can be especially useful in a situation when people do not want to do tests for coronavirus infection because they believe that the danger associated with the pandemic has already largely passed. It also helps to “detect early signals of the COVID-19 outbreak”. The article clarifies that the coronavirus can be detected in body fluids even before the symptoms of infection appear.

According to the publication, this method was used earlier this month in the city of Davis (California), whose population is about 68 thousand people. This allowed us to establish that the number of cases of coronavirus infection is probably increasing in a number of its areas. Later, ads were placed in three districts of the city, urging residents to pass tests for infection.

The method was used in the United States, in particular, in student dormitories, prisons, and other places where many people live at the same time. “In some cases, the authorities went further to individual testing,” the publication says.

According to Johns Hopkins University, more than 34.4 million cases of coronavirus infection were detected in the United States, more than 610 thousand people died. The country ranks first in the world in both indicators.
