Yellow fungus is a fatal disease because it starts internally and it's important for a person to seek medical treatment as soon as he/she notices any symptoms.
The treatment for yellow fungus is the amphotericin b injection, which is an anti-fungal drug.
Poor hygiene mostly causes the yellow fungus infection and getting rid of old food and faeces helps in containing its spread. Too much humidity can also cause the infection as it promotes the proliferation of bacteria and fungus. The humidity can remain between 30% and 40%.
