In the News

Less than two weeks ago, just one locality in Maryland was colored orange on the U.S. Centers for Disease Control and Prevention’s map — signifying “substantial” coronavirus spread. None were red, which would mean the level of transmission is high. As of Tuesday, all but two counties were in the substantial or high transmission zone.

The CDC's advice for keeping your child protected from this highly contagious version of the coronavirus now and this fall: Mask up in schools and other crowded venues. And make sure everyone age 12 and older in the family gets a COVID-19 shot.  

Schools are reopening just as the rise of the more contagious Delta variant shifts the fight against Covid-19. Masks are back on top of the policy agenda. And confusion reigns.

The Centers for Disease Control and Prevention is advising even vaccinated people to return to mask-wearing in indoor public spaces located in areas with higher rates of coronavirus infections.

 As the Delta variant sweeps the world, researchers are tracking how well vaccines protect against it — and getting different answers.

SARS-CoV-2, the virus that causes COVID, is special in one way, though: more than any other pathogen, it has provided the public at large with lessons in immunology—and terms such as “breakthrough infections” and “herd immunity” have gained a broad familiarity.

The WHO says people who are fully immunized should hold off on getting a third shot while so many people in the world are still waiting for their first. More than 80% of all COVID vaccines given so far have been administered in upper-income nations.

Classrooms are opening their doors to a different pandemic. Here is how to think about risk.

Throughout the pandemic, scientists have been learning more about SARS-CoV-2, the virus that causes COVID. But there are still big questions, like how long the virus can survive in your body.

Experts are warning that the greatest threat to the pandemic recovery in the United States are the large swaths of Americans who remain unvaccinated

In May it seemed as if the pandemic were being beaten back. But in the past two weeks, COVID-19 cases have increased 171%. The death rate is up 19% over the week before. Breakthrough infections are making the news, hitting sports teams and politicians.

Companies are beginning to bring employees back to the office after more than a year of remote work. But as COVID-19 vaccination rates slow and the Delta variant spreads, a return to work may mean adjusting to a new normal.
