Also called infectious or parotitis
Pathophysiology

Paramyxovirus is found in the saliva of an infected person.
-
It’s transmitted by droplets or by direct contact with the saliva of an infected person.
Causes
-
Necrosis of acinar and epithelial duct cells in the salivary glands and germinal epithelium of the seminiferous tubules
-
Perivascular and interstitial mononuclear cell infiltrating with edema, due to infection of the central nervous system (CNS) or glandular tissues (or both)
-
Virus replication in the epithelium of the upper respiratory tract, leading to viremia
