Background: It is of utmost importance to monitor any change in the epidemiology of fungal diseases that may arise from a change in the number of the at-risk population or the availability of local data.
Objective: We sought to update the 2015 publication on the incidence and prevalence of serious fungal diseases in Uganda.
Methods: Using the Leading International Fungal Education methodology, we reviewed published data on fungal diseases and drivers of fungal diseases in Uganda. Regional or global data were used where there were no Ugandan data.
Results: With a population of ~45 million, we estimate the annual burden of serious fungal diseases at 4,099,357 cases (about 9%). We estimated the burden of candidiasis as follows: recurrent Candida vaginitis (656,340 cases), oral candidiasis (29,057 cases), and esophageal candidiasis (74,686 cases) in HIV-infected people. Cryptococcal meningitis annual incidence is estimated at 5553 cases, Pneumocystis pneumonia at 4604 cases in adults and 2100 cases in children. For aspergillosis syndromes, invasive aspergillosis annual incidence (3607 cases), chronic pulmonary aspergillosis (26,765 annual cases and 63,574 5-year-period prevalent cases), and prevalence of allergic bronchopulmonary aspergillosis at 75,931 cases, and severe asthma with fungal sensitization at 100,228 cases. Tinea capitis is common with 3,047,989 prevalent cases. For other mycoses, we estimate the annual incidence of histoplasmosis to be 646 cases and mucormycosis at 9 cases.
Conclusion: Serious fungal diseases affect nearly 9% of Ugandans every year. Tuberculosis and HIV remain the most important predisposition to acute fungal infection necessitating accelerated preventive, diagnostic, and therapeutic interventions for the management of these diseases.

How common are serious fungal infections in Uganda? Why was the study done? This study was conducted to provide an updated understanding of the occurrence and impact of serious fungal diseases in Uganda. The aim was to monitor changes in the epidemiology of fungal diseases related to shifts in the at-risk population or the availability of local data. What did the researchers do? Utilizing the Leading International Fungal Education methodology, the research team systematically reviewed published data on fungal diseases in Uganda. In instances where Ugandan data was unavailable, regional, or global data were incorporated. This method allowed for a thorough examination of the incidence and prevalence of various serious fungal diseases, considering the local context. What did the researchers find? With a population of approximately 45 million, the study estimated that nearly 9% of Ugandans, totalling around 4,099,357 individuals, are affected by serious fungal diseases annually. Notable findings include the prevalence of recurrent Candida vaginitis, oral candidiasis, and oesophageal candidiasis in HIV-infected individuals. Cryptococcal meningitis and Pneumocystis pneumonia were identified as significant contributors, along with various aspergillosis syndromes and widespread cases of tinea capitis. What do the findings mean? These findings underscore the substantial impact of serious fungal diseases on the health of almost 9% of the Ugandan population each year. Recognizing tuberculosis and HIV as major predisposing factors, the study calls for urgent interventions to prevent, diagnose, and treat these diseases effectively. The identified targets, including improved access to essential antifungal medications, training of health care workers on fungal diseases, and increasing access to essential diagnostics. These interventions can significantly contribute to improving public health outcomes in Uganda.
