Mumps, also known as PAROTITIS, is an infectious disease caused by the mumps virus. It is characterized by swelling of the salivary glands, fever, headache, and muscle aches. In some cases, it can lead to complications such as meningitis, encephalitis, and deafness. The disease is spread through contact with saliva or respiratory secretions from an infected person. Vaccination is the best way to prevent mumps.
