An 87-year-old man with COVID-19 developed a rare and severe fungal infection in his airways caused by Aspergillus fumigatus.

Despite starting antifungal medications, his condition rapidly worsened leading to organ failure and death. This case highlights how COVID-19 can leave patients vulnerable to serious secondary fungal infections that require immediate recognition and treatment.

A woman developed a serious respiratory condition called allergic bronchopulmonary mycosis caused by Cordyceps farinosa, a fungus that normally infects insect larvae. She worked in a laboratory breeding mice in a mountainous area and developed persistent cough and congestion. Doctors identified the fungus using DNA testing and treated her by removing the fungal material from her airways and removing her from the workplace, which led to complete recovery.
