People may choose to mask at any time. To reduce the risk of being infected with COVID-19 variants and possibly spreading it to others, The Centers for Disease Control and Prevention (CDC) recommends that people with symptoms, a positive test, exposure to someone with COVID-19 or at high risk for severe illness should wear a well-fitted, high quality mask. Options include:

  • N95 or KN95 masks – shown to provide the highest levels of protection.
  • A disposable mask under a cloth mask - also offers increased effectiveness.
  • A cloth mask with at least two layers of tightly woven fabric.
