Testing runoff water near homeless encampments to detect COVID

Testing environmental water to monitor COVID-19 spread in unsheltered encampments

To better understand COVID-19's spread during the pandemic, public health officials have expanded wastewater surveillance. These efforts track SARS-CoV-2 levels and health risks among most people, but they miss people who live without shelter, a population particularly vulnerable to severe infection.

To fill this information gap, researchers reporting in Environmental Science & Technology Letters tested flood-control waterways near unsheltered encampments, finding similar transmission patterns as in the broader community and identifying previously unseen viral mutations.

Researchers develop more broadly protective coronavirus vaccine

Scientists have been searching for the optimal coronavirus vaccine since the COVID-19 pandemic started. The mRNA vaccines developed through the federal government's "Operation Warp Speed" program were a massive innovation; however, annually updating those boosters for specific SARS-CoV-2 variants is inefficient for scientists and patients.

SARS-CoV-2 is just one member of the Sarbecovirus (SARS Betacoronavirus) subfamily (others include SARS-CoV-1, which caused the 2002 SARS outbreak, as well as other viruses circulating in bats that could cause future pandemics).
