CORONAVIRUS RESEARCH HIGHLIGHTS: 1-MINUTE READS
Summer-camp outbreak infects many children
At least 250 campers and staff members tested positive for COVID-19 after attending an overnight camp in the US state of Georgia. All campers and staff were required to test negative for the virus fewer than 13 days before arrival, and campers did not mix with those sleeping in other cabins. Staff wore masks, but campers did not. “This investigation adds to the body of evidence demonstrating that children of all ages are susceptible to SARS-CoV-2 infection and, contrary to early reports, might play an important role in transmission,” write the study authors.

Immune cells found in unexposed people
T cells that are prepared to attack SARS-CoV-2 exist in some people who have never been exposed to the virus. Researchers surveyed blood samples from around 100 people for T cells that react to the SARS-CoV-2 spike protein. Reactive cells were found in 83% of people with COVID-19, as well as 35% of healthy blood donors. These cells might have been primed by past infections with related coronaviruses. We still don’t know whether these cells offer real-world protection against SARS-CoV-2.
