Is Wearing Masks Still Necessary?

Wearing masks is still necessary in certain situations, especially if you're at high risk of getting severe COVID-19 or if there's a high level of transmission in your community ¹. This includes people who are not up to date on their COVID-19 vaccine, have chronic health conditions, or are moderately to severely immunocompromised ¹.

*When to Wear a Mask:*

- _High-Risk Individuals_: Wear a mask in indoor public spaces, especially if you have a weakened immune system, chronic health conditions, or are older ¹.

- _High-Transmission Areas_: Wear a mask in public indoor spaces, regardless of vaccination status ¹.

- _Traveling_: Consider wearing a mask on public transportation, especially if you're at high risk ².

- _Poor Ventilation_: Wear a mask in indoor spaces with poor ventilation ².

*Choosing the Right Mask:*

- _N95 Respirators_: Offer the best protection, with 95% filtration efficiency ² ¹.

- _KN95 Masks_: Provide good protection, with 95% filtration efficiency, but may have a less snug fit ² ¹.

- _Surgical Masks_: Offer less protection than N95s and KN95s, but still block large droplets ².

Remember, wearing a mask is still a good idea if it makes you feel more comfortable, even if you're not at high risk ¹. Always follow local guidelines and take other prevention measures, like getting vaccinated and washing your hands frequently.
