The estimated burden of fungal diseases in Mali.

Mali is a developing country facing several health challenges with a high rate of tuberculosis (TB) and a moderate HIV infection burden. Little is known or done about fungal diseases, yet they represent a significant public health problem in certain populations. The aim of this study was to estimate the national burden of fungal disease, and summarize data, diagnostic and treatment gaps. We used national demographics and PubMed searches to retrieve articles on published data on these infections and at-risk populations (pulmonary TB, HIV/AIDS patients, patients receiving critical care etc.) in Mali. The estimated Malian population was 21,251,000 in 2020 (UN), of which 45% were children <14 years. Among HIV patients, we estimate an annual incidence of 611 cryptococcosis, 1393 Pneumocystis pneumonia, 180 histoplasmosis and >5,700 esophageal candidiasis and some microsporidiosis cases. Our prevalence estimates for tinea capitis are 2.3 million, for recurrent vulvovaginal candidiasis 272,460, ∼60,000 fungal asthma and 7,290 cases of chronic pulmonary aspergillosis (often mistaken for TB). Less common acute fungal infections are probably invasive aspergillosis (n=1230), fungal keratitis (n=2820), candidaemia (>1,060) and mucormycosis (n=43). Histoplasmin was found in 6% in general population. A few cases of mycetoma are described in Mali. Many WHO Essential medicines and Diagnostics are not available in Mali. This shows a marked disparity in documented and estimated cases of fungal diseases in Mali. These infections are underestimated due to the lack of accurate diagnosis tools and lack of support for fungal diseases diagnosis and management.
