Incidence of endemic mycoses among cohort of Medicare beneficiaries, by region, United States, 1999–2008*
| 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) |
| South | 3.5 (3.0–4.1) | 0.6 (0.4–0.9) | 1.0 (0.8–1.4) |
| West |
1.1 (0.7–1.7) |
15.2 (13.4–17.2) |
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.
