DESIGN Epidemic investigation, population-based skin test survey, and case-control study. SETTING Ventura County,(More)
Surveillance for coccidioidomycosis (CM) and a case-control study for risk factors among adults were conducted in Kern County, California. From January 1995 through December 1996, 905 cases of CM were identified, for an annual incidence of 86 cases per 100,000 population. A total of 380 adults were enrolled in the case-control study: 77 had severe pulmonary(More)

OBJECTIVE To summarize investigations of sprout-associated outbreaks. DESIGN Matched case-control studies. SETTING California. PATIENTS Outbreak-associated patients and matched population(More)
Coccidioidomycosis, a mild flulike illness in approximately 40% of infected persons, progresses to severe pulmonary or disseminated disease in 1% to 10% of symptomatic cases. We examined host genetic influences on disease severity among class II HLA loci and the ABO blood group. Participants included African-American, Caucasian, and Hispanic persons with(More)
