Infectious Diseases Experts: Keep Masking Up

The Infectious Diseases Society of America agrees with the Centers for Disease Control and Prevention’s recommendation that everyone wear well-fitting, high-quality masks in indoor public settings when COVID-19 community levels are high. IDSA recommends masks also be worn on public transportation systems, although the federal mask mandate has been lifted.

IDSA further emphasizes that the authority to implement community mitigation measures, such as mask requirements, during a public health emergency must rest with public health authorities like CDC and state and local health officials.

Factors the public should consider when deciding whether to wear a mask include personal health risk, community COVID-19 levels and the guidance of public health officials. Wearing a mask indoors in public settings offers protections both for you and those you encounter.

Many people in our communities remain at risk for severe disease from COVID-19. Children under 5 still cannot get vaccinated. While vaccination significantly lowers everyone’s risk of severe disease, people with weakened immune systems, chronic diseases or those who are older still have some risk even when vaccinated.  

The nation’s infectious diseases experts and most public health officials still encourage people to wear masks in certain settings. As the pandemic continues to evolve, the public should be prepared for updated guidance. Listen to the experts before you put your masks away.
