The mumps virus is spread by contact with saliva infected with tiny droplets that spread into the air around you when you sneeze, cough, sing or talk. Mumps2 is usually manifested in a headache, fever and swelling of the salivary glands which are painful. In boys or men, a painful swelling of the testicles is also possible, called orchitis3. This disease can cause complications including deafness or meningitis. Fortunately, an effective vaccine is available, usually in combination with the vaccine against rubella and measles viruses (MMR vaccine).
