ENDEMIC HPS CONTEXT (SEPARATE FROM 2026 OUTBREAK)
Separate from the 2026 cruise ship outbreak: the U.S. sees ~30–40 endemic HPS cases annually, primarily in the Southwest from Sin Nombre virus via deer mice.
Primary vector: Deer mouse (Peromyscus maniculatus) — Southwest US
US HPS CFR: ~36% historically (Sin Nombre strain)
Prevention: N95 + rubber gloves when cleaning rodent-contaminated areas. Never dry-sweep. Wet with 10% bleach solution first.
