BACKGROUND: Evidence suggests geographic expansion in histoplasmosis, a fungal infection caused by Histoplasma spp. Establishing historical and modern population immunity to histoplasmosis is needed to contextualize future trends and ensure that providers give it diagnostic consideration.
METHODS: To summarize what is known regarding the distribution of histoplasmosis globally, we conducted a systematic review of studies reporting prevalence of lifetime or recent exposure to Histoplasma spp, assessed via skin or serological tests, respectively.
RESULTS: We included 224 studies, including 171 skin test surveys and 44 serological surveys, spanning 66 countries and all 6 World Health Organization regions. Prevalence of infection exceeded 10% in studies from the Americas, Southeast Asia, and Africa, with substantial variation across population subgroups. Most studies used nonrepresentative sampling.
CONCLUSIONS: Histoplasmosis likely exists along a global gradient. Surveillance and research efforts must shift to address its broad distribution and ensure timely diagnosis and treatment, especially in areas not traditionally considered endemic.
