Who Is At Risk for Histoplasmosis?
People who have lived in states in the Ohio and Mississippi River Valley are at higher risk. Many people have been exposed to the fungus that causes histoplasmosis, but few go on to develop OHS. If you know that you had histoplasmosis, watch for vision changes that could signal the symptoms of OHS.
Most people who have histoplasmosis don’t know it. Have your eyes examined for histo spots if you ever lived somewhere with high rates of histoplasmosis.
