A doctor has provided insights into the investigation surrounding the hantavirus outbreak on the cruise ship MV Hondius, which resulted in three deaths and 11 reported cases. The 20 British passengers who were on board have returned to the UK and are currently in isolation.
Return and Isolation of Passengers
The 20 Brits, along with a German UK resident and a Japanese passenger, were flown to Arrowe Park Hospital on the Wirral on Sunday. They will remain there for three days before being allowed to go home, after which they must isolate for 42 days. If they cannot return home, alternative accommodation will be arranged.
Doctor's Analysis of Virology Data
Dr. Ahmed, an A&E doctor with over 555,000 TikTok followers, described the virology results as "quite interesting." He explained that the data suggests the virus originated from a zoonotic source, specifically rat urine or droppings, for the first two infected patients. Furthermore, genetic sequencing of all subsequent positive cases among passengers showed identical viral genomes. This indicates that all infections on the ship stemmed from the same source, likely the same person, confirming human-to-human transmission.
Dr. Ahmed noted that while this confirms human transmission, key questions remain unanswered. It is unclear whether the virus has mutated to become more aerostable, facilitating quicker human-to-human spread, or if the ship's recycled air environment enabled such rapid and widespread transmission.
Current Status of Cases
A French woman who tested positive for hantavirus is in intensive care in stable condition at a Paris hospital. One of 18 evacuated passengers flown to the US has also tested positive but remains asymptomatic, while another had mild symptoms. A British man with hantavirus is being treated in Johannesburg, South Africa, and is reportedly improving. Another British national is isolating at home on Tristan da Cunha, a remote South Atlantic island.
WHO Update
Dr. Tedros Adhanom Ghebreyesus, Director-General of the World Health Organization, provided an update at a press briefing. He stated that nearly 150 people from 23 countries were on the ship for weeks, describing the situation as frightening and noting that some passengers faced mental breakdowns. He added that there is currently no sign of a larger outbreak, but the situation could change given the virus's long incubation period, and more cases may emerge in the coming weeks.
Ship's Status and Captain's Message
As of Monday evening, Oceanwide Expeditions reported that 27 people remain on board the MV Hondius, including 25 crew members and two medical staff. Captain Jan Dobrogowski expressed gratitude to passengers and crew in a video message, acknowledging the extreme challenges of the past weeks. He praised their patience, discipline, and kindness, and extended thoughts to those who lost their lives.
Strict infection control measures were implemented during the journey to Arrowe Park, with all individuals wearing personal protective equipment. The hospital site features self-contained flats with bedrooms, bathrooms, kitchens, and lounges. Janelle Holmes, CEO of Wirral University Teaching Hospital NHS Foundation Trust, confirmed that welfare checks will be conducted, and symptomatic passengers will be transferred to Royal Liverpool University Hospital's Tropical and Infectious Diseases Unit.
