Jornal Do Brasilia - US health agency loosens Covid mask guidelines

"We're in a stronger place today as a nation with more tools to protect ourselves and our communities from Covid-19," said Rochelle Walensky, director of the Centers for Disease Control and Prevention (CDC) in a call with reporters.

The changes involve the metrics used to determine whether people should mask up.

Under current guidance, this is pegged to case rates -- with 95 percent of the country considered areas of high or substantial transmission, and thus covered by mask advisories.

The new metrics also include Covid hospitalizations and local hospital capacity, to create a new measure known as "Covid-19 community level."

Residents can look up on the CDC website whether their area is green, yellow or orange on a national map.

More 70 percent of the population live in areas that aren't advised to mask up according to the new framework, including schools in the green or yellow areas.

The revised guidelines don't however apply to transport systems. A federal rule on that will be reviewed in mid-March when it is set to expire.

The United States is coming out of its latest Covid wave, driven by the Omicron variant, which while highly transmissible, leads to less severe outcomes among people who were vaccinated or had a prior infection.

In recent weeks, the administration of President Joe Biden has increased its rhetoric around normalization as the pandemic transitions to a new endemic phase.

Both Republican and Democrat-led states and cities have already taken the lead, either dropping their mandates or setting imminent timelines for doing do.
