Hantavirus is not easily spread, but is global heating upping our exposure?

Argentina back in spotlight 30 years after first person-to-person transmission was documented in Patagonia

An outbreak in rural communities 30 years ago in the Patagonia area of Argentina led scientists, for the first time, to document person-to-person transmission of hantavirus, which until then had been known only to spread through contact with rodents.

Nearly a decade ago another outbreak, also in Patagonia, provided detailed evidence of inter-human transmission when an infected 68-year-old rural worker attended a birthday party in a small village. The infection spread and resulted in 11 deaths.
