Parotitis, more commonly known as “mumps”, is a contagious viral disease that affects one or both parotid glands (major salivary glands) situated behind the ascending rami of the mandible. It is caused by the mumps virus and typically affects children and teenagers, although it may also cause infections in sensitive adults. In general, the disease produces lifetime immunity, and it may be prevented by the administration of the combined MMR vaccine. Mumps may affect other glands in the body, the central nervous system and the testicles. The most frequent complications are meningitis and testicular inflammation which may lead to infertility. This inflammation of the testicle is also known as mumps orchitis. It is not very frequent, affecting 1 per million inhabitants per year among the general population. […]
