Which type travels through saliva or mucous and can be spread by sneezing?

• A. Direct
• B. Droplet
• C. Indirect
• D. Airborne

Answer: (B)

The main idea is how respiratory infections spread through droplets produced when someone sneezes, coughs, or talks. Droplet transmission happens when larger respiratory droplets contain pathogens in saliva or mucus and travel short distances. Sneezing can propel these droplets quickly, and they often land on nearby people’s eyes, noses, or mouths, or on surfaces that others touch. Because the droplets are relatively heavy, they don’t linger in the air for long and typically don’t travel far, unlike airborne particles that can stay suspended and travel longer distances. This is different from indirect transmission via contaminated objects or from direct contact, which involve different pathways. So, the mechanism described—traveling through saliva or mucous and spreading by sneezing—fits droplet transmission.
