Prior to the emergence of the omicron variant, frequent testing using RATs was known to be a better strategy than infrequent testing using PCR tests. RATs detect infection early, which allows for ...

First discovered a year ago in South Africa, the SARS-CoV-2 variant later dubbed "omicron" spread across the globe at incredible speed. It is still unclear exactly how, when and where this virus ...

In a recent study posted to the bioRxiv* preprint server, researchers performed deep mutational scanning (DMS) for the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) Omicron variant of ...

Speed is everything in the race against COVID-19’s Omicron variant, the fastest version of the virus we’ve seen to date. Its dizzying rise to dominance in the United States threatens to overwhelm our ...

The BA.2.75 sublineage of the B.1.1.529 (omicron) variant of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) may escape neutralizing antibodies. The BA.2.75 sublineage (primarily the BA.2 ...

You’ve tested negative for COVID using a rapid antigen test (RAT), but are a close contact of a positive family member and have symptoms. So you might be wondering if you’re really COVID-negative or ...

A new publication from Opto-Electronic Advances, 10.29026/oea.2023.220201 discusses deep-ultraviolet photonics for the disinfection of SARS-CoV-2 and its variants (Delta and Omicron) in the cryogenic ...

The protection conferred by natural immunity, vaccination, and both against symptomatic severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection with the BA.1 or BA.2 sublineages of the ...

Researchers from Osaka University compare the sensitivity of RATs and PCR tests for the Omicron variant of COVID-19 Osaka, Japan - Testing plays a crucial role in humanity’s strategy to mitigate the ...
