Final answer:
Covid-19 triggers a cytokine storm in older patients, while histoplasmosis, coccidioidomycosis, and blastomycosis are caused by dimorphic fungi. Aspergillosis is not caused by a dimorphic fungus. Valley fever is another name for coccidioidomycosis.

Covid-19 triggers a unique pathophysiological characteristic known as a cytokine storm, leading to widespread tissue damage and multi-organ failure, especially in patients aged 60 and older.
Histoplasmosis, coccidioidomycosis, and blastomycosis are caused by dimorphic fungi, unlike aspergillosis which is caused by a mold.
Valley fever is another term for coccidioidomycosis, an infection caused by inhaling spores from the soil fungus Coccidioides immitis.
