President Joe Biden will reportedly announce new guidance on face masks from the Centers for Disease Control and Prevention on Tuesday, CNN reports.

Biden’s announcement will reportedly explain whether people who have been vaccinated need to wear face masks outside. However, the unnamed sources told CNN that the wording of the speech and the guidance remains unclear.

Dr. Anthony Fauci, the chief White House medical adviser on the coronavirus, told CNN that the face mask guidance could be updated soon, too.

  • He said the CDC “will be coming out with updating their guidelines of what people who are vaccinated can do and even some who are not vaccinated.”
CDC might revise its guidance on wearing masks outside

Last week, NBC News reported that the CDC was considering changing its guidelines for wearing face masks outside. And Dr. Rochelle Walensky, the director of the CDC, also said on the “Today” show that the CDC is looking at changing its rules.

  • “We’ll be looking at the outdoor masking question, but also in the context of the fact that we still have people who are dying of COVID-19,” she said, according to NBC News.

But Krystal Pollitt, a Yale School of Public Health assistant professor of epidemiology, told The Washington Post that there might not be a hard and fast rule for masks. Situations may dictate what happens.

  • “There is not necessarily a straightforward rule. A lot of it really comes down to still thinking of the level of risk of the situation around you and the people around you, especially,” she said.
