A mumps outbreak in Los Angeles County and surrounding areas has sickened more than 40 people, according a health alert from Los Angeles County Department of Public Health.
A majority of cases have occurred among men who have sex with men. However, some women and heterosexual men have also been infected with the virus.
"Most transmissions appear to have occurred at large venues such as athletic clubs, bars, theaters and nightclubs," said the LAC DPH in the health alert. "The majority of cases have had no documentation of complete vaccination; however, some cases were fully vaccinated."
The mumps can cause fever and painful, swollen salivary glands, among other symptoms. It is a highly transmissible virus contracted via person-to-person contact. Two doses of the measles-mumps-rubella vaccine are 88 percent effective at preventing mumps, according to the CDC.
