TL;DR
An initial suspected case of hantavirus in the US was confirmed as a false positive. The total outbreak cases have decreased from 11 to 10, with no new deaths. The situation is now under control, but monitoring continues.
The US health authorities confirmed that a recent suspected hantavirus case was a false positive, leading to the reduction of outbreak cases from 11 to 10. This clarification comes amid ongoing monitoring and containment efforts. The development is significant for public health response and reassurance.
Initially, there were 11 reported cases of hantavirus infection linked to an ongoing outbreak, including one death. However, recent laboratory testing revealed that the US suspected case was a false positive, confirmed by health officials. This reclassification reduces the total confirmed cases to 10, with no additional fatalities reported since May 2.
The case that was reclassified involved a patient who had tested positive but was later found not to have hantavirus after further testing, according to sources familiar with the investigation. The individual, who had been under observation, is now considered uninfected, and no further transmission has been reported.
Health authorities emphasize that the overall outbreak remains under control, with ongoing testing and contact tracing. The total number of fatalities remains at three, involving a Dutch couple and a German woman, with no new deaths linked to the outbreak.
Why It Matters
This correction provides reassurance that the outbreak is not expanding and that the public health response remains effective. It also highlights the importance of laboratory testing accuracy in managing infectious disease outbreaks. For affected regions and international partners, this update helps refine risk assessments and containment strategies.

Background
The outbreak initially involved 11 cases, including individuals from multiple countries, linked to a ship evacuation in the Canary Islands. The cases included passengers and crew, with some disembarked and repatriated. The situation prompted international monitoring and quarantine measures, with authorities emphasizing the incubation period of up to six weeks for potential new cases.
The US has been closely monitoring 41 individuals potentially exposed, including those who disembarked the ship and shared flights with infected persons. The incident was part of a broader effort to contain a suspected hantavirus outbreak, which is known for its high mortality rate and transmission through rodent contact.
“The recent laboratory tests confirm that the suspected case was a false positive, and there is no evidence of ongoing transmission in the US.”
