For 213 million people, the number affected by serious fungal diseases infections in Ghana, South Africa, Ethiopia and Taiwan has been unknown, until today. At the Gulf Conference on Clinical Microbiology and Infectious Diseases in Dubai posters showed the remarkably high numbers afflicted, especially in Africa, an estimated 4%, 7% 9% and 2% respectively. The data from Taiwan compared the National Health Insurance database and estimates based on patients at risk, as for other countries.

Burden of fungal disease posters:

 

In Africa, tinea capitis dominates the overall fungal burden with an estimated 8.6 million affected in only these 3 countries, and very few in Taiwan. Globally, it is thought that about 200 million children have tinea capitis.

The very large number of pulmonary TB cases in South Africa and Ghana (322,000 (60% in HIV) and 44,000 (22% in HIV) in 2017) leads to a very large number of cases of chronic pulmonary aspergillosis (CPA). In South Africa an estimated 99,350 cases of CPA are present (175/100,000), the highest prevalence in the world, and more than in Russia (126/100,000), Nigeria, the Philippines (78/100,000), Pakistan (70/100,000) and Vietnam (61/100,000). In Ghana, there are an estimated 12,620 CPA cases (44/100,000) a similar prevalence to Uganda (46/100,000) and Bangladesh (41/100,000).

Cryptococcal meningitis and Pneumocystis pneumonia (PCP) in AIDS are also relatively common in these countries, and in South Africa, the majority of PCP cases were in children. Ethiopia probably has more cases of cryptococcal meningitis than South Africa or Ghana, but its population is almost twice the size of South Africa.

Only in Ghana could an estimate of fungal keratitis annual incidence be made: 810 cases, likely an underestimate. In Taiwan, 8.2% of microbial keratitis cases are caused by fungi, but there is no overall number.

These four country estimates bring to 79 the number of countries with a country burden estimate, 57 of which are published (Iran in press).  Abstracts are all posted on LIFE news: http://www.life-worldwide.org/media-centre/news and published papers on the Aspergillus Website and on GAFFI: https://gaffi.org/media/academic-papers/
