Infectious diseases can be transmitted to humans, or between humans and animals, by airborne viruses and bacteria, known as infectious aerosols. Current protective measures that individuals can take to avoid inhaling such aerosols are either marginally effective (personal face masks) or impractical (self-contained breathing apparatuses).
