Within the past three weeks, half of the states that instituted mask mandates in response to the ongoing COVID-19 pandemic have lifted that requirement.

Rhode Island and Delaware ended mask-or-vaccine provisions for indoor spaces on Feb. 11, one day after New York ended its latest mask mandate.

«We’re in a much better place than we were several weeks ago in the middle of the omicron surge of COVID-19 cases and hospitalizations,» Governor John Carney, a Democrat, said in a statement.

Those states were followed by California and Connecticut, which lifted their indoor masking requirements on Tuesday.

The highly transmissible omicron variant prompted some states and cities to reinstitute mask mandates during the winter holiday season, but as infections and hospitalizations drop sharply, those requirements are quickly ending.

Which states are ending mask mandates?

New York ended its mask mandates for everyone on Feb. 10, though cities, counties and individual businesses can still enforce mask-or-vaccine requirements, but it’s no longer required by state law.

Nevada Gov. Steve Sisolak lifted the state’s mask requirement the same day.

«Masks are still a great tool we have to slow the spread of the virus,» Sisolak said in a statement. «The state will no longer require masks in public places, but employers and organizations, including school districts, may set their own policies, and I encourage them to work with their employees and communities to ensure that policies are in place.»

Delaware Gov. John Carney lifted the state’s universal mask mandate on Feb. 11, the same day Rhode Island also announced an immediate end to mask-or-vaccine requirements for indoor spaces.

What is the federal mask mandate?

In December, due to concerns around the more virulent omicron variant, the Biden administration extended its mask mandate for those traveling by trains, buses and airplanes. Originally intended to expire on Jan. 18, the measure is now set to end March 18.

The Biden administration has not said yet if it plans to extend the federal mask mandate further.

What does the CDC recommend about masking?

The CDC still encourages everyone age 2 years and older, vaccinated or unvaccinated, to continue wearing masks when in public indoor spaces, especially if in a high COVID-19 transmission area.

But the agency is expected to loosen its indoor masking guidelines as early as next week, reportedly switching to a benchmark that looks ath the level of severe disease and hospitalizations in a given community, rather than a blanket nationwide directive.

The CDC originally stated in May 2021 that vaccinated people did not need to wear masks anywhere, but reversed course in July when the delta variant of COVID-19 led to higher numbers of infections, hospitalizations and deaths.

People outdoors generally do not need to wear masks, the agency says, unless they are in extended close contact with other people.

What is the World Health Organization’s position on masks?

The World Health Organization’s current guidance is that wearing a well-fitting mask that covers the nose and mouth is recommended indoors in areas with poor ventilation or where social distancing cannot be maintained, «irrespective of vaccination status or history of prior infection.»
