There is a mumps outbreak in New York with 16 people at New York State University infected, 8 of who are on the swim team. Additionally, one of the university students was in cahoots with a high schooler, who came down with the illness, and now high schools in the area fear outbreaks themselves.
Mumps is a paramyxovirus with no treatment. A two-part vaccine gives protection to many people who receive it. It has direct transmission, and is highly contagious. The virus has an incubation period of 16-18 days, and symptoms include fever, headache, fatigue, and swollen salivary glands. For now, people should avoid sharing glasses and utensils in at-risk areas, and the swim team should probably be told to get a little… less close to one another.
