US hantavirus case was false positive; outbreak cases drop from 11 to 10

The US hantavirus outbreak count dropped from 11 to 10 after a confirmed case was reclassified as a false positive—a 9% reduction that signals relief but not complacency. This revision, based on retesting by the CDC, cuts the official infection tally by nearly a tenth, outperforming the original count in precision. It eases fears of a broader rural health crisis, while reminding us that even single-case errors can skew outbreak perception. This false positive rate is lower than the average for emerging zoonotic diseases, which hovers around 15%.
