Disparities in Fungal Priority Pathogens List
In a recent article published in The Lancet Microbe, researchers scrutinized the World Health
Organization’s (WHO) fungal priority pathogens list (FPPL), revealing disparities between its
rankings and the actual fungal disease burdens. The FPPL was established in October 2022 to
address challenges in fungal disease diagnosis, treatment, and research. While acknowledging its
significance, researchers highlighted the need for a revised prioritization list that addresses
regional disparities more effectively.
Proposed Prioritization Adjustments
The study emphasizes several key fungal pathogens and their implications on global health.
Mucorales, initially categorized as high-priority pathogens, emerged as a greater threat,
particularly in regions like India during the COVID-19 pandemic. Similarly, Candida spp.
infections, despite their high mortality rates, may not be fully represented in the FPPL, especially
with emerging antifungal resistance. Histoplasmosis, caused by Histoplasma capsulatum, also
demands attention due to its broader global distribution, necessitating improved diagnostic
capacities.
Recommendations for Enhanced Prioritization
To address the limitations of the FPPL, researchers propose region-specific customization of
priorities based on WHO regions. They advocate for the prioritization of four major pathogens
globally: Cryptococcus, Aspergillus spp., Candida spp., and Pneumocystis jirovecii. Additionally,

of Coccidioides and Paracoccidioides spp. in the Americas and prioritizing Mucorales in
Southeast Asia and the Eastern Mediterranean. Furthermore, they highlight the importance of
higher prioritization for Histoplasma spp. in the Americas and Africa, as well as Talaromyces
marneffei in Southeast Asia and the Western Pacific.
Conclusion
While the FPPL represents a significant step in addressing fungal infections on a global scale, the
study underscores the need for tailored prioritization to better reflect regional disease burdens. By
advocating for adjustments in the FPPL based on geographical considerations, researchers aim to
enhance global awareness, research efforts, and ultimately, control of fungal infections. Efforts to
customize prioritization strategies are crucial steps toward mitigating the impact of fungal
diseases worldwide.
