Signs of slowdown are everywhere after huge increases in vacation bookings, traveling and eating out earlier this year. Southwest Airlines, Airbnb and restaurants are starting to see a pullback.

Much of the blame for Brazil's coronavirus disaster lies with Jair Bolsonaro, who has enabled a domestic tragedy that now threatens the world, says analyst Robert Muggah.

In the future, different circumstances will likely determine which vaccine or booster a person receives, based on their antibodies — and which variant is common in their region.

The German chancellor defended her government's decision to extend a COVID-19 lockdown into March, as she issued a stark warning about fast-spreading new strains.

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.

They don't yet understand why the coronavirus variant called P.1 has spread so explosively there. Its set of mutations seem especially dangerous. And this week P.1 was confirmed in the U.S.

It appears to be 50% more infectious, and researchers predict the new coronavirus variant could start to dominate in the U.S. by March. The time to prepare is now, they say.

A new and more transmissible variant is threatening to overwhelm England's health care system, the prime minister said.
