Hantavirus spillovers & lab lapses — MV Hondius Andes outbreak escalates globally
Key Questions
What is the current status of the Hantavirus outbreak associated with the MV Hondius?
The WHO has confirmed 11 cases and 3 deaths in the escalating outbreak. It originated from a soil spillover at an Argentina landfill involving an ornithologist, with exposures reported in California, Dutch hospitals, King County, and Scotland.
How is Hantavirus spreading in this outbreak and what is the risk level?
Transmission is primarily zoonotic with rare person-to-person spread at a 6% attack rate; factors include HVAC systems and an 18-day incubation period. CDC briefings assess overall risk as low, with 42-day monitoring for contacts and inconclusive PCR results.
What issues have been identified with Hantavirus PCR testing and lab samples?
PCR sequences have been reported to match human DNA, questioning test accuracy, and no FDA-approved kits exist. Australian labs confirmed 323 missing vials from a 2021 freezer incident with no ongoing risk.
