The UK Health Security Agency has confirmed that nine asymptomatic individuals from Saint Helena and Ascension Island are expected to arrive in the United Kingdom as part of the government’s continuing response to the hantavirus outbreak linked to the expedition cruise ship MV Hondius.
The passengers are being repatriated as a precautionary measure and will complete their self-isolation in the UK, where they can be monitored closely by the National Health Service High Consequence Infectious Diseases network. On arrival, they will be transferred to Arrowe Park Hospital, a facility with extensive experience in managing infectious disease incidents and supporting individuals requiring specialist observation.
According to Dr Meera Chand, the UKHSA is working alongside the Foreign, Commonwealth and Development Office, the NHS and authorities in the UK Overseas Territories to ensure that all affected individuals receive appropriate medical checks, guidance and support throughout their isolation period. She said the agency remains committed to safeguarding both the passengers involved and the wider public.
The current response follows several days of coordinated action by UK health authorities. Earlier updates confirmed that a medic from Ascension Island who developed symptoms was separately evacuated to the High Consequence Infectious Diseases unit at Guy’s and St Thomas’ NHS Foundation Trust for specialist assessment. Although the individual has not been confirmed as a hantavirus case, officials said the transfer was undertaken as a highly precautionary measure because severe cases can deteriorate rapidly and require intensive care.
Health officials continue to stress that the risk to the general public remains very low. All individuals being transported to the UK are undergoing medical checks before travel to ensure they are asymptomatic, and strict infection prevention and control procedures are being maintained throughout the repatriation process.
The outbreak first came to international attention after several passengers aboard the MV Hondius were identified as confirmed or suspected cases of hantavirus. The vessel had visited a number of remote locations, including St Helena, Ascension Island and Tristan da Cunha, prompting an extensive international response involving the World Health Organization and multiple governments.
British nationals returning from the ship have been asked to isolate for up to 45 days, reflecting the virus’s potential incubation period. During this time, they receive regular testing, daily monitoring and tailored support from UKHSA health protection teams and NHS clinicians. Several individuals who initially stayed at Arrowe Park have since been permitted to complete their isolation at home after negative PCR tests and detailed public health assessments confirmed that it was safe to do so.
To strengthen the response overseas, UKHSA has also deployed a rapid response mobile laboratory to St Helena. Specialists from the UK Public Health Rapid Support Team, a partnership between UKHSA and the London School of Hygiene & Tropical Medicine, are providing on-island PCR testing and infection prevention support to local healthcare teams.
Hantaviruses are carried primarily by rodents and are transmitted through contact with infected droppings or urine. Infections in humans are rare, but some strains can cause serious illness ranging from flu-like symptoms to severe respiratory complications. Person-to-person transmission is uncommon, though it has been documented in specific strains.
For many people in the UK and across the African diaspora, especially those with family ties to British Overseas Territories and international travel routes, the incident highlights how quickly global health concerns can affect communities across borders. It also underscores the importance of coordinated public health systems and rapid government response when dealing with emerging infectious diseases.
The UK government has repeatedly emphasised that passengers, their families and local communities are being supported throughout what has been an unsettling experience. Medical teams continue to monitor everyone involved while maintaining robust measures to protect public health.
