San joaquin fever
San Joaquin fever
(Science: infectious disease) A fungal infection caused by the fungus coccidioides immitis. Exists in two forms: primary disease, which is a self-limited respiratory infection (requires no treatment) and a progressive form (diffuse and granulomatous), that can involve almost any part of the body. Approximately 60% of infections cause no symptoms and are identified only by skin testing. Immunocompromised patients (aIDS) are at greatest risk for disseminated disease.
