Testing

Vaccines are finally starting to roll out, but the virus is spreading faster than ever — and killing thousands of Americans daily. 

Reducing the spread of COVID-19 over the next several months — while vaccines are being distributed — has the potential to save more than 100,000 American lives.

According to research by Johns Hopkins University, communities of color often have less access to COVID-19 testing.

CBS News correspondent Mark Strassmann spoke with Jennifer Nuzzo, a senior scholar at the Johns Hopkins Center for Health Security, about areas where people don't have access to coronavirus tests, known as testing deserts.

Johns Hopkins experts Beth Blauer and Dr. Jennifer Nuzzo on the lack of federal standards around COVID testing data. 

If you think a negative test result means you don't have coronavirus, you could be wrong. It can take days before a new infection shows up on a COVID-19 test.

Backers of a third type of coronavirus test, developed by a Nobel Prize winner using cutting-edge CRISPR technology, say it has the potential to be rapid, accurate and inexpensive.

After struggling to ramp up coronavirus testing, the U.S. can now screen several million people daily, thanks to a growing supply of rapid tests. But the boom comes with a new challenge: keeping track of the results.

A new experiment has found that a $5 rapid COVID-19 test may be nearly as effective as the slower, more complex polymerase chain reaction test.

The coronavirus pandemic may have caused tens of thousands of more deaths than previously thought, according to a report published Monday in the peer-reviewed journal JAMA.

Dr. Joshua M. Sharfstein, professor at the Johns Hopkins Bloomberg School of Public Health, coauthors a piece on the importance of isolation following a COVID-19 diagnosis.

Faster, cheaper coronavirus tests are starting to hit the market, and some experts say these technologies could give the U.S. the ability to adopt a new, more effective testing strategy.
