Coronavirus Coverage

Things seem to be looking up as the US crosses into year three of the COVID-19 pandemic.

Americans can now order a second set of free at-home COVID-19 rapid antigen tests from the federal government.

The rollout of the US government’s COVID-19 test-to-treat program is underway, with in-pharmacy clinics ordering shipments of COVID-19 antiviral medications, and some locations expecting to offer the service within days.

Mask mandates may be lifting in many parts of the United States, but don’t ditch your face coverings just yet.

The US Centers for Disease Control and Prevention has released a new measure for determining COVID-19 community levels.

The US Food and Drug Administration on Thursday revised the emergency use authorization for Evusheld, a monoclonal antibody against COVID-19 for immunocompromised people and those who cannot be vaccinated for medical reasons, to double the initial dose. People who’ve already received the drug should go back for an additional dose as soon as possible, the agency said.

New metrics from the US Centers for Disease Control and Prevention indicate that about 28% of people in the United States live in a county where they need to wear masks indoors, a significant drop from previous metrics that advised 99% of people in the US to keep their masks on.

Children ages 8 to 10 put out about a quarter of the aerosolized particles as adults do when breathing, speaking and singing, according to a new study.

On the heels of concerning new lab and animal experiments suggesting that BA.2 may be capable of causing more severe disease than the original Omicron strain, two new studies are helping to show how well human immunity is defending against this strain in the real world.

As the COVID-19 pandemic enters its third year, scientists are finding that the coronavirus has far-reaching effects on health beyond the acute phase of illness.

After the Omicron coronavirus variant made a record number of US children sick in January, children’s hospitals across the United States braced for what has come with every other spike in the COVID-19 pandemic: cases of a rare but dangerous condition called multisystem inflammatory syndrome in children, commonly known as MIS-C. But a number of hospitals say the expected surge in cases hasn’t showed up — at least not yet.
