Which term describes particles of liquids sprayed from the nose or mouth when a person sneezes, coughs, sings, talks, or laughs?

Droplets are the particles of liquid expelled from the nose or mouth during sneezing, coughing, singing, talking, or laughing. They are relatively large and travel only short distances before gravity pulls them to surfaces or they deposit on nearby people. That’s why infection prevention emphasizes barriers and distance to block these larger particles from reaching eyes, nose, or mouth. In contrast, aerosols are much smaller particles that can stay suspended in the air longer and travel farther, which requires different control measures like ventilation. Spatter refers to large liquid splashes that contaminate surfaces, not the general respiratory particles themselves, and germs are microorganisms, not the physical particles expelled.
