Can Mumps Cause Injury and Death?

white man thinking

Complications and death from mumps infections are rare.  Complications include inflammation of the testicles in males, which can, in rare cases, result in atrophied testicles and lead to sterility. 

Aseptic meningitis may also develop as a complication of mumps.  Rarely, mumps may also cause pancreatitis,  encephalitis,    oophoritis (inflamed ovaries),  hearing loss,    mastitis,    myocarditis,    thyroiditis,  nephritis,    arthritis,    diabetes,  and thrombocytopenic purpura.  Spontaneous abortions (miscarriage) in pregnant women infected with mumps have also been reported .

No mumps related deaths have been reported in recent years. 

IMPORTANT NOTE: NVIC encourages you to become fully informed about Mumps and the Mumps vaccine by reading all sections in the Table of Contents, which contain many links and resources such as the manufacturer product information inserts, and to speak with one or more trusted health care professionals before making a vaccination decision for yourself or your child.
