Histoplasmosis, n = 357 Coccidioidomycosis, n = 345 Blastomycosis, n = 74
Midwest 6.1 (5.3–7.1) 2.0 (1.5–2.6) 1.1 (0.7–1.5)
Northeast 1.1 (0.7–1.7) 0.5 (0.3–0.9) 0.05 (0.01–0.30)

0.1 (0.03–0.50)
All of United States 3.4 (3.0–3.7) 3.2 (2.9–3.6) 0.7 (0.6–0.9)

*Random national sample of 5% of Medicare beneficiaries with claims during 1999–2008; selected for cohort were those who were age >65 years at start of follow-up, had full Medicare coverage (parts A and B, not in a Medicare Advantage plan) for at least 13 consecutive months; lived in the 50 US states or Washington, DC; and did not have claims for any endemic mycosis during a 12-month period before the start of follow-up. Mean age of those with mycoses was 75.7 years.
