droplet infection
noun
An infection transmitted from one individual to another by droplets of moisture expelled from the upper respiratory tract through sneezing or coughing.
Droplet transmission occurs when bacteria or viruses travel on relatively large respiratory droplets that people sneeze, cough, drip, or exhale. They travel only short distances before settling, usually less than 3 feet. These droplets are loaded with infectious particles.
They can be spread directly if people are close enough to each other. More often, though, fomites are involved. The droplets land on hands, toys, tables, mats, or other surfaces, where they sometimes remain infectious for hours. Hands that come in contact with these surfaces (doorknobs, telephones, pens, etc.) become contagious. When the infectious hand touches the nose or eyes, the infection is able to enter the new person.
Many common infections can spread by droplet transmission in at least some cases, including: Common cold, Diphtheria, Fifth disease (erythema infectiosum), Influenza, Meningitis, Mycoplasma, Mumps, Pertussis (whooping cough), Plague, Rubella, Strep (strep throat, scarlet fever, pneumonia).
