Advances in the treatment of invasive fungal disease

by Zhuan Zhang, Gerald F. Bills, Zhiqiang An

With over 300 million severe cases and 1.5 million deaths annually, invasive fungal diseases (IFDs) are a major medical burden and source of global morbidity and mortality. The World Health Organization (WHO) recently released the first-ever fungal priority pathogens list including 19 fungal pathogens, considering the perceived public health importance. Most of the pathogenic fungi are opportunistic and cause diseases in patients under immunocompromised conditions such as HIV infection, cancer, chemotherapy, transplantation, and immune suppressive drug therapy. Worryingly, the morbidity and mortality caused by IFDs are continuously on the rise due to the limited available antifungal therapies, the emergence of drug resistance, and the increase of population that is vulnerable to IFDs. Moreover, the COVID-19 pandemic worsened IFDs as a globe health threat as it predisposes the patients to secondary life-threatening fungi. In this mini-review, we provide a perspective on the advances and strategies for combating IFDs with antifungal therapies.
