Surgical Masks – How Effective Are They? (3 Key Points)

1. Moderately effective at reducing infection risk
   Surgical masks do help lower the spread of respiratory infections like flu, RSV, and COVID-19 by blocking droplets. However, they are less protective than N95/FFP2 masks because they don’t seal tightly around the face.

2. Best at blocking outgoing droplets (source control)
   Surgical masks are especially effective when worn by an infected person, as they reduce how many virus-laden droplets are released into the air when coughing, sneezing, or talking.

3. Limited protection against tiny airborne particles
   They offer weaker protection against very small aerosol particles compared to respirator masks. This means they are helpful in low-to-medium risk settings, but less reliable in crowded or poorly ventilated indoor spaces.

In short: Surgical masks are useful and scientifically proven to reduce transmission, but they provide moderate protection, while N95/FFP2 masks provide high protection.
