Overview

Pharyngitis is contagious, so anyone in close proximity to someone with the illness, is at risk. Social situations with prolonged close interpersonal contact are associated with a higher incidence of the disease, such as in schools, dormitories, or military barracks. Droplet spread has been postulated as the method of transmission, and outbreaks have been associated with contaminated food and water, but fomites are not thought to play a role. The degree of contagion is probably related.[1]
