What's your opinion on treating histoplasmosis?

Don't (usually): Histoplasmosis is almost always a self limited disease. While we have excellent drugs to treat it, they should be reserved for people who have symptomatic disease or those with severe immune compromise (chemotherapy, hiv, , transplants or other immunosuppressive treatments). Most histo is only discovered by accident, and in those cases, treatment provides no help and can have side effects. ...Read more

Is histoplasmosis heritary?

No: Histoplasma is a dimorphic fungus that exists as a mold in the environment and a yeast in humans. Everyone in the endemic areas for the fungus is equally susceptible to be exposed but there may be different susceptibility for the symptoms and risk for spread outside the lung.
