Hantavirus in Costa Rica

Overview

Costa Rica is in the Americas hantavirus context. There is no major endemic hantavirus strain in this curated dataset; the country may still record imported cases.

The Costa Rican pygmy rice rat (Oligoryzomys costaricensis), now recognised as the principal reservoir of Choclo orthohantavirus, is widely distributed in Costa Rica. To date Costa Rica has not reported a human hantavirus outbreak comparable to neighbouring Panama; the country is included for ecological completeness.
