What happened

A map circulating online has been used to falsely suggest that the hantavirus is spreading rapidly in Europe, but its creator says it was intended to track news coverage.

Why it matters

A map shared widely online has been used to falsely claim that the Andes strain of the hantavirus is spreading rapidly across Europe and North America.

Common ground

The pictures are screenshots of a map from HantavirusMap.com, which have spread on X and TikTok in the aftermath of a hantavirus outbreak on the cruise ship MV Hondius.

Perspective signals

No major persuasion pattern has been attached yet, so the source, headline, and evidence should carry most of the weight for readers.
