SARS-CoV-2, the virus that causes COVID-19, takes time to build up in the body, like many other viruses and bacteria that cause respiratory illness. Typically it takes two to three days to test ...

As new variants of COVID 19 keep appearing, many people have expressed concern over whether these variants can be detected by ...

Researchers from the Department of Biology at IISER Pune, in collaboration with teams at University of Toronto and Pontificia ...

Accurate rapid diagnostic tests for SARS-CoV-2 infection would be a useful tool to help manage the COVID-19 pandemic. Testing strategies that use rapid antigen tests to detect current infection have ...

A new SARS-CoV-2 variant, NB.1.8.1, may now account for more than one-third of all COVID-19 cases in the US, health officials say.

Explainer - Do you still have to isolate if you get Covid? Can you get free RAT tests? Here's what you need to know.

Background: Antigen rapid diagnostic tests (RDT) for SARS-CoV-2 are fast, broadly available, and inexpensive. Despite this, reliable clinical performance data from large field studies is ...

Rapid diagnostic tests (RDTs) are critical for preparedness and response against an outbreak or pandemic and have been highlighted in the 100 Days Mission, a global initiative that aims to prepare the ...

Objective To assess the diagnostic accuracy of antigen compared with reverse transcriptase (RT)-PCR testing in an asymptomatic athlete screening programme and to monitor infection in college ...

We then assessed the properties of NB.1.8.1 by virological experiments. A lentivirus-based pseudovirus assay showed that the infectivity of NB.1.8.1 was significantly higher (2·5-fold; p<0·0001) than ...
