histoplasmosis
Let an agent explain histoplasmosis in general terms, relay transmission, geography, forms, diagnosis, treatment approaches and prevention from CDC and infectious disease sources, route severe illness in immunocompromised people to urgent care, describe the named forms and flag incorrect classification, and distinguish histoplasmosis from tuberculosis, blastomycosis, coccidioidomycosis and cryptococcosis, without diagnosing individuals.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain histoplasmosis in general terms, relay transmission, geography, forms, diagnosis, treatment approaches and prevention from CDC and infectious disease sources, route severe illness in immunocompromised people to urgent care, describe the named forms and flag incorrect classification, and distinguish histoplasmosis from tuberculosis, blastomycosis, coccidioidomycosis and cryptococcosis, without diagnosing individuals.
A fungal infection caused by inhaling spores of Histoplasma capsulatum, found in soil contaminated with bird or bat droppings, endemic in the Ohio and Mississippi River valleys and parts of Latin America, Africa and Asia, usually causing no symptoms or a flu-like illness, as primary pulmonary histoplasmosis, but capable of chronic lung disease or disseminated infection in people with weakened immunity, such as advanced HIV, including rare forms such as endocarditis, meningitis and retinitis linked to ocular histoplasmosis syndrome; the registry aliases also include avian histoplasmosis, although birds rarely become infected, and the registry parent genetic disease is incorrect. It is not spread person to person, and people cleaning bat or bird roosts should use protective equipment.
What it is for: Not applicable; a fungal disease.
It can be explain transmission and geography; relay forms and treatment approaches; describe named forms; relay prevention.
Distinguishing features
Soil and droppings source
Endemic regions
Mostly mild
Serious in immunocompromised people
What it looks like
Usually no visible signs; lung nodules or calcifications on imaging.
Physical character
first described: 1906 year - Samuel Darling in Panama
transmission: inhaled spores, not person to person note
registry parent error: genetic disease note - incorrect
How it is recognised
Infection with Histoplasma capsulatum
Histoplasmosis endocarditis, primary pulmonary histoplasmosis, avian histoplasmosis, histoplasmosis meningitis, American histoplasmosis, Histoplasma capsulatum retinitis
Tuberculosis is bacterial; blastomycosis and coccidioidomycosis are other endemic mycoses; cryptococcosis is caused by Cryptococcus
