Wastewater Analysis can Detect New Variants of the Virus

Analyzes of wastewater may detect new variants of SARS-CoV-2 in a given area even before clinical sequencing of the virus that causes covid-19, indicates a study by the American Society for  (SAM) released on Tuesday.

“We know that there are individuals with infection and that, because they are asymptomatic, they can never be tested”, said the person in charge of the study, who applies a method of sequencing the RNA, in the San Francisco Bay area.

The researchers found that the main SARS-CoV-2 genotypes detected in wastewater were identical to those measured clinically in this region, which allows, according to the study, to understand which variants of the virus are present in the population over time.

“Knowing that SARS-CoV-2 is present in a population is the first step in helping to control the spread of the virus, but knowing which variants that are present provide very useful additional information”, defended the SAM researcher, who integrates about 30,000 scientists from various fields, including health professionals.
