The best way to protect yourself and others is to use many safety tools, such as getting vaccinated and boosted, wearing a mask indoors and avoiding places where COVID-19 spreads more easily.

COVID-19 Spreads More Easily in Some Places

COVID-19 is more likely to spread in places:

  • Where people are not vaccinated

  • Where people are not wearing masks

  • Where it’s crowded and people are close to each other

  • With poor airflow, such as indoor locations

To lower your chance of getting sick, choose to spend time in places where COVID-19 is less likely to spread:

  • Places where people are fully vaccinated

  • Places where people are wearing masks

  • Places that are not crowded

  • Outdoor places

Upgrade Your Mask

Not all masks provide the same protection. Wear a mask with the best fit, protection and comfort for you. No matter which mask you choose, make sure it fits well with no gaps.


  • N95 (also best for wildfire smoke)

    • Choose a size and model that fits your face and has no gaps

    • If you wear an N95 respirator, you should not wear an additional face covering over or under the respirator, as it can interfere with the seal to the face


  • KF94

  • KN95

  • Double mask

    • Wear two masks (disposable mask underneath AND cloth mask on top)


  • Surgical mask


  • Cloth mask

    • It should fit snugly and have at least three layers

    • A cloth mask is better than no mask
