Treatment
Typical treatment of severe disease first involves treatment with amphotericin B, followed by oral itraconazole.Liposomal preparations of amphotericin B are more effective than deoxycholate preparations. [en.wikipedia.org]

Treatment options are not yet well codified. But medical treatment is the first alternative and may include surgery or contention with brace. Amphotericin B, ketoconazole and itraconazole are the most used molecules. [scirp.org]
Both patients with cutaneous disease responded to treatment, although one was lost to follow-up. [ncbi.nlm.nih.gov]
Prognosis
Disseminated disease has a grave prognosis, especially if the liver and spleen are involved. Amphotericin B, itraconazole or fluconazole are the drugs of choice [6, 36, 1690, 2302]. [drfungus.org]
It is worth considering this pathology at least for three reasons: it usually mimicks a malignant jaw tumor; it may constitute a migrant pathology; and prognosis is commonly favorable with amphotericin B treatment. [ncbi.nlm.nih.gov]
What is the prognosis of histoplasmosis? People with mild symptoms of histoplasmosis usually resolve the disease on their own without treatment. In more severe cases, the prognosis is good for those who receive appropriate treatment. [medicinenet.com]

Etiology
Care must be taken to ensure that B. dermatitidis is not confused with the etiologic agent of histoplasmosis duboisii since they both occur in Africa. [drfungus.org]
The natural reservoir of the etiological agent has only been recently discovered in a bat cave in Nigeria. The status of asymptomatic infection is not certain. [ncbi.nlm.nih.gov]

Prevention
There is no vaccine or preventive medication against Histoplasmosis. Information last updated: December 11, 2017 [iamat.org]
How Can One Prevent Histoplasmosis? There is no vaccine to prevent histoplasmosis. The CDC recommends people "avoid areas with accumulations of bird or bat droppings, especially if you have a weakened immune system. [emedicinehealth.com]
Management of African histoplasmosis encountered many problems because of the availability of amphotericin B and cost of the biochemical tests in order to prevent major side effects in case of failure of oral antimycotic drug. [link.springer.com]
Prevention[edit] Washing one's hands, a form of hygiene, is an effective way to prevent the spread of infectious disease.[36] Techniques like hand washing, wearing gowns, and wearing face masks can help prevent infections from being passed from one person [en.wikipedia.org]
