Mumps

Definition of Mumps: A disease caused by an infection with mumps virus. This disease commonly presents with fever, headache, fatigue, or eventually parotitis. Transmission is by contact with respiratory secretions, directly or indirectly.

ICD 11 Code For Mumps

  1D80  Mumps

1D80.0 Mumps without complication

1D80.1 Orchitis due to mumps virus

Definition of Orchitis due to mumps virus: Within a few days of infection the mumps virus can attack the testicular glands leading to abrupt onset of fever ranging from 39-41 to 41ºC, severe testicular pain, scrotal swelling and erythema. Mumps induced orchitis typically presents 1-2 weeks after parotitis. The virus’ infiltration into the testicular glands can cause parenchymal inflammation, separation of seminiferous tubules and perivascular interstitial lymphocyte infiltration. Testicular atrophy can result from a rise in intratesticular pressure. Complications include oligospermia, azoospermia, and asthenospermia, which can contribute to subfertility. Infertility is more common in patients with bilateral mumps orchitis and is estimated to occur in approximately 13% of all patients. Sterility is rarely induced by mumps orchitis.

Inclusions:

  • Mumps orchitis

1D80.2 Meningitis due to mumps virus

Definition of Meningitis due to mumps virus: A disease of the meninges, caused by an infection with mumps virus. This disease is characterised by photophobia, vomiting, fever, arthralgia, headache, stiff neck, convulsions, or seizures. This disease may also present with pale, blotchy skin or a distinctive rash. Transmission is by haematogenous spread to the meninges after inhalation of infected respiratory secretions or droplet transmission. Confirmation is by identification of mumps virus in a buccal swab or blood sample.

Inclusions:

  • mumps meningitis

1D80.3 Encephalitis due to mumps virus

Definition of Encephalitis due to mumps virus: An inflammatory process of the brain, frequently with evidence of meningeal involvement, due to infection by mumps virus. The clinical manifestations are usually acute, with fever and variable combinations of convulsions, impaired mental state, and focal deficits. The spinal fluid may show a cellular reaction and elevated protein. Diagnosis is by neuroimaging, spinal fluid analysis and culture, PCR, and serologic tests.

Inclusions:

  • Mumps encephalitis

1D81.1 Mononucleosis due to cytomegalovirus

Definition of Mononucleosis due to cytomegalovirus: A disease typically caused by an infection with cytomegalovirus. This disease commonly presents with extreme fatigue, fever, acute pharyngitis, body aches, or lymphadenopathy. Transmission is by direct contact with infected body fluids, commonly through saliva.

Definition of Cytomegaloviral hepatitis: A disease of the hepatic system, caused by an infection with human cytomegalovirus. This disease is characterised by fever, acute pharyngitis, fatigue, lymphadenopathy, or jaundice. Transmission is by direct contact with infected body fluids. Confirmation of an active infection is by identification of human cytomegalovirus in blood, saliva, urine, or other body tissue samples.
