What is the latest news about coronavirus outbreaks? Scientists at the University of California at Berkeley can tell you this.
According to one report, the scientists collected human waste samples from sewers in the San Francisco Bay Area to identify “hot spot” areas where coronavirus is most common.
The scientists told the Bay Area’s FOX 2 that evidence of coronavirus infection was often present in the waste samples, and they decided that sewer sampling would be more efficient than going door-to-door to obtain human samples people.

Team leader Kara Nelson, professor of civil and environmental engineering at UC Berkeley, told the radio: “Natural wastewater contains waste from hundreds to even millions of people in a single sample.
“So if you can collect a representative wastewater sample and analyze it, you can get a huge amount of information that you might not be able to get through individual testing,” she said. more.
Wastewater treatment agencies from three Gulf counties are supporting the project, with a fourth district expected to be involved soon, the report said.
Samples are collected at a “drainage warehouse”, where waste from multiple sewers is concentrated in a single pipe or treatment station. Scientists told FOX 2, the samples could include waste from a few thousand to several hundred thousand residents.

The DNA in the samples was then examined to determine the presence of the coronavirus, with UC Berkeley̵7;s Department of Cellular and Molecular Biology assisting in the process.
The UC Berkeley team hopes to share its methods and information with other regions of the United States to help them study infection rates in those regions, Nelson told FOX 2.
