Testing

Johns Hopkins Center for Health Security Senior Scholar Jennifer Nuzzo discusses increased vaccinations across the United States, the role of testing in fighting COVID-19, and company vaccine mandates.

The Centers for Disease Control and Prevention this week said vaccinated people without symptoms mostly don’t need to get tested even if exposed to the virus.

Consumers will be able to buy rapid coronavirus tests without a prescription this week at three national chain retailers, an expansion that comes as the nation's vaccination effort accelerates and states relax distancing requirements and mask mandates. 

The U.S. has continued a downward trend, with a 30% decrease in the number of daily COVID-19 tests.

Testing might be more important now than ever, and new testing technology and government funding and initiatives are making getting tested faster, easier, and cheaper than it’s ever been.

With case numbers still high, coronavirus testing remains essential, experts say, but the goals and approach will change as vaccines roll out.

The U.S. needs to ramp up the use of rapid COVID-19 testing in order to curb the pandemic and prepare for reopening.

The Biden administration is trying to transform the United States’ COVID-19 testing system by regularly screening millions of Americans.

As more U.S. residents receive their COVID-19 vaccinations, testing for the virus has plummeted, dropping by a third in two months.

The number of new Covid-19 cases is dropping in the United States, but a decline in testing threatens this progress.

Widespread testing is crucial in controlling the spread of the coronavirus and squashing new outbreaks, but the amount of testing in the United States has fallen by 30 percent in recent weeks.

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