Overview

While cryptococccus and candida infections occur worldwide, other fungal infections tend to cluster in specific geographical regions.[1][2] The most common cause of fungal meningitis is Cryptococcus neoformans.[3][4][2]

Epidemiology

Cryptococcus Meningitis

  • It is the most common cause of fungal meningitis.
  • Cryptococcus meningitis occurs worldwide but it is highly prevalent in southeast Asia and southern and east Africa where the prevalence of HIV is elevated.[5]
  • It is a common opportunistic infection in patients with HIV and it is considered as an AIDS defining lesion. [6]
  • The mortality is high (10-30%).[7]
