Are the mumps fatal

Answer 1

From eMedicine Pediatrics:

"Death due to mumps is rare; more than half of the fatalities occur in persons older than 19 years.

Mumps encephalitis occurrence ranges as high as 5 cases per 1000 reported mumps cases, and males are affected 3-5 times more frequently than females. Permanent sequelae are rare, but the reported encephalitis case-fatality rate has averaged 1.4%.

Approximately 10% of all infected patients develop a mild form of meningitis, which could be confused with bacterial meningitis. Encephalitis, transient myelitis, or polyneuritis is rare. Unilateral hearing loss is associated with mumps infection but is also rare.

Orchitis occurs in 10-20% of patients; subsequent sterility is rare. Oophoritis is quite rare and is usually a benign inflammation of the ovaries. Other rare complications include myocarditis, nephritis, Arthritis, thyroiditis, pancreatitis, thrombocytopenia purpura, mastitis, and pneumonia. These usually resolve within 2-3 weeks without sequelae."
