Gov. Gavin Newsom announced the plan on Friday as part of an effort to accelerate in-person learning across the state.

Scientists are evaluating domestic COVID-19 variants to see whether they pose a new threat, as public health experts warn the U.S. needs better surveillance to spot mutations and slow their spread.

The Biden administration is promising 61 million rapid at-home tests by the summer. But critics say that's too few and way too late.

The Biden administration must do more to identify and track three fast-spreading mutations of the COVID-19 virus, researchers say. Clearer CDC guidelines for masks and reopening would help too.

All three coronavirus variants that appear to spread faster have now been found in the United States, raising concerns they could spark a new deadly surge and outrun treatments and vaccines.

As feared, the coronavirus varant first discovered in South Africa has been detected in the United States for the first time.

The Biden Administration is taking a far more aggressive, nationally coordinated approach to the pandemic. We hear more about how it plans to support vaccination efforts.

Daily numbers of new cases are finally starting to wane, and hospitalizations are down slightly. But health care systems are still overburdened and another resurgence remains a threat.

The deaths caused by the pandemic appear to be shortening overall life expectancy in the U.S. by 1.13 years, which would be the largest single decline in at least 40 years.

Mask-wearing hit an all-time high, but other COVID-19 precautions are less common now than last spring, a survey finds. Experts worry we're ill-prepared for the spread of more infectious new variants.

The pandemic has never been this bad in the U.S. There is not enough data yet to say whether the holidays accelerated the coronavirus surge, but many experts believe that the case.

Experts argue that pushing out more COVID-19 vaccine doses to states sooner may be a good idea, even if it means there's a chance some people's second dose gets delayed.

President-elect Biden plans to release almost all available doses of COVID-19 vaccines, stepping away from the Trump administration policy to hold back about half of the supplies for booster shots.

Critics say the vaccine rollout suffers from the same problems that have plagued the response to the pandemic for testing and other responses: lack of aggressive and coordinated federal leadership.

The U.S. conducts nearly 2 million coronavirus tests daily. A new analysis shows millions more are needed to protect the most vulnerable. Use our tool to see how your state is doing.

A CDC panel recommends that people over 75 and front-line essential workers should be prioritized as the next group to be vaccinated against the coronavirus.

Epidemiologists are still puzzling over how much of an impact Thanksgiving had on the pandemic in the U.S. Meanwhile, infections, hospitalizations and deaths are still surging as Christmas approaches.

The Food and Drug Administration on Tuesday authorized the test. It will cost about $30 and be available by January, according the Australian company that makes it, Ellume.

The new tests produce results completely at home within 15 minutes. Experts say they could be a 'game-changer' in helping people find out quickly if they need to isolate.

As the first patient to receive an experimental treatment that relied on the gene-editing technique CRISPR continues to do well 17 months later, more patients seem to be benefiting, too.
