Long-tailed pygmy rice rat at the heart of new hantavirus theories

The long-tailed pygmy rice rat has emerged as the linchpin in investigations of the recent Andes virus outbreak that sickened dozens aboard the MV Hondius cruise liner.

Long-tailed pygmy rice rat: the Andes virus reservoir

Scientists from Reuters and the Pan‑American Health Organization confirm the rodent carries the pathogen with a ↓ 12% drop in regional rodent‑borne cases since 2022, yet the virus surged aboard the ship, infecting ↑ 3 crew members within 48 hours. Understanding this host‑pathogen link could reshape public‑health protocols, says an epidemiologist.

“The discovery forces us to rethink quarantine measures for maritime travel,”

notes a senior official at the AP News bureau. Meanwhile, researchers are mapping the rat’s habitat across the Andes, hoping to curb future spillovers.
