Abstract

Purpose In Bangladesh there are several published papers on superficial mycoses. Deep mycoses are also recognized as an important emerging problem. Here, we estimate the annual incidence and prevalence of serious fungal infections in Bangladesh. Method Demographic data were obtained from world population reports and the data on TB and HIV extracted from the online publications on tuberculosis in Bangladesh and Asia Pacific research statistical data information resources AIDS Data HUB. All the published papers on fungal infections in Bangladesh were identified through extensive search of literature. We estimated the number of affected people from populations at risk and local epidemiological data. Results Bangladesh has a population of ~162.6 million, 31% children and only 6% over the age of 60 years. The pulmonary TB caseload reported in 2014 was 119,520, and we estimate a prevalence of 30,178 people with chronic pulmonary aspergillosis, 80% attributable to TB. An anticipated 90,262 and 119,146 patients have allergic bronchopulmonary aspergillosis or severe asthma with fungal sensitization. Only 8,000 people are estimated to be HIV-infected, of whom 2900 are not on ART with a CD4 count <350µL, Pneumocystis pneumonia and cryptococcal meningitis being rare. Superficial mycoses are very common with Trichophyton rubrum as the predominant etiological agent (80.6%). Numerous cases of mycotic keratitis have been reported from several parts of Bangladesh. Candida bloodstream infection was estimated based on a 5 per 100, 0000 rate (8,100 cases) and invasive aspergillosis based primarily on leukemia and COPD rates, at 5,166 cases. Histoplasmosis was documented in 16 cases mostly with disseminated disease and presumed in 21 with HIV infection. Conclusion This study constitutes the first attempt to estimate the burden of several types of serious fungal infections in Bangladesh.
