Is COVID-19 on airplane air filters?

...

With this support, the researchers will specifically look for evidence of pathogens, including SARS-CoV-2, on used filters collected from airplanes. If viruses can be found on filters, then filters from could be used as a new way to track when and where viruses enter the country. Rather than testing travelers individually, it might be possible to monitor entire flights with one test...

New study suggests two paths toward 'super immunity' to COVID-19

New laboratory research from Oregon Health & Science University reveals more than one path toward robust immunity from COVID-19.

A new study finds that two forms of immunity— following vaccination or natural followed by vaccination—provide roughly equal levels of enhanced immune protection.

Researchers gain new insights into antibody response against viral COVID variants

In the journal Science, researchers from Deutsches Zentrum für Neurodegenerative Erkrankungen (DZNE) and Charité–Universitätsmedizin Berlin present new findings on the immune response against the coronavirus SARS-CoV-2.

Their study is based on investigations of antibodies elicited by infection with the Beta variant of the virus.

Rapid COVID tests: Their accuracy and efforts to improve them

 

Why rapid COVID tests aren't more accurate and how scientists hope to improve them

How much should you trust the results of a rapid antigen test? That's a question many people are asking these days amid recent research and anecdotes suggesting these tests may be less sensitive to omicron. Researchers are working fast to figure out what's going on and how to improve the tests.

That includes people like Dr. Wilbur Lam, a professor of pediatrics and biomedical engineering at Emory University and one of the lead investigators assessing COVID-19 diagnostic tests for the federal government. His research team began evaluating rapid antigen tests against live samples of the omicron variant last December in the lab, and in early assessments, he says, some tests failed to detect the coronavirus "at a concentration that we would have expected them to catch it if it were another variant."

That finding prompted the Food and Drug Administration to update its online guidance in late December to note that, while rapid antigen tests do detect the omicron variant, "they may have reduced sensitivity."
