Summary Introduction
To explain:
Death of humans due to “nonpathogenic fungal species” due to a multistage meningitis outbreak linked to steroid injections in
Introduction:
Fungal species releases spores in soil, water, and air. They germinate to produce hyphae and mycelium which are thread like structures. These penetrate into hosts like humans. This takes place during the process of breathing when a person inhales spores. These spores reach lungs and cause infection.
