Insights

Cytomegalovirus mononucleosis can cause fever of unknown origin in new fathers. This diagnosis should be considered in fathers of young children presenting with prolonged fever.

Area of Science:

  • Infectious Diseases
  • Virology
  • Pediatrics

Background:

  • Pyrexia of unknown origin (FUO) presents a diagnostic challenge.
  • Cytomegalovirus (CMV) is a common virus that can cause various clinical syndromes.

Observation:

  • A 35-year-old man, nine months postpartum, presented with prolonged fever.
  • Extensive investigations were required to determine the cause of his fever.

Findings:

  • The patient was diagnosed with cytomegalovirus mononucleosis.
  • This diagnosis was established after a comprehensive workup for FUO.

Implications:

  • Cytomegalovirus mononucleosis should be included in the differential diagnosis for FUO in new fathers.
  • Early consideration of CMV mononucleosis can expedite diagnosis and management in this specific demographic.
