Mumps virus or epidemic parotitis is characterised by a non-purulent, firstly unilateral and later mostly bilateral swelling of the parotid gland. It proceeds in 60per cent of the patients asymptomatic. After 12-26 days of incubation, both fever and pain uni- or bilateral on facial areas occur. Characteristic is a protruding ear lobe as the result of the considerable swelling of the parotic gland. The oral manifestation is a reddened, oedematous papilla parotidea with clear, serous saliva. The virus is generally self-limiting and does not need any medical intervention except symptomatic treatment. Complications are male infertility through oophoritis, meningoencephalitis, pancreatitis or orchitis.
