A rare case of histoplasma and cryptococcus coinfection in an apparently immunocompetent child

Journal of Dr. NTR University of Health Sciences
Histoplasma capsulatum and Cryptococcus neoformans fungal infections are mainly found in immunocompromised individuals, especially in patients with HIV/AIDS. However, histoplasma-cryptococcus coinfection in immunocompetent hosts is very rare. This rarity
