During a press briefing on Friday, the World Health Organization (WHO) announced a revision in the case count of the hantavirus outbreak linked to the MV Hondius cruise ship in the South Atlantic. The count has been adjusted from 11 to 10 cases after a previously reported case in the US was found to be a false positive. Dr. Stephen Kornfeld, an American doctor aboard the ship, was initially included in the outbreak count due to a PCR test that yielded a faint positive result. However, this result was later deemed inconclusive. Kornfeld had developed a minor illness in early April, shortly after the first confirmed hantavirus case on the ship, which resulted in the death of a Dutch passenger. After further testing, including repeat PCR and serology tests, Kornfeld tested negative for hantavirus, indicating he has neither an active nor a prior infection. Consequently, he has been transferred from the biocontainment unit to a quarantine unit at the Nebraska Medical Center, where he and other US passengers are being monitored.
