lab findings:
• WBC count may be normal and reduction in granulocytes is normal
• paired acute and convalescent serum antibody studies
• elevated serum amylase
• virus isolation from throat, CSF, and urine

course and prognosis

The associated microorganism, a paramyxovirus, is spread by droplet infection or direct contact with materials contaminated with infected saliva. It usually resolves in two weeks.

Orchitis occurs in 20% of postpubertal males and is usually unilateral; testicular atrophy may ensue. Other complications include: meningoencephalitis; pancreatitis; prostatitis; nephritis; myocarditis; mastitis; polyarthritis.
