Joint statements issued on 6, 8 and 9 May by UKHSA, the Department of Health and Social Care and the Foreign, Commonwealth and Development Office set out a managed response to the hantavirus outbreak on the MV Hondius. The 9 May statement said the UK government was working with international authorities ahead of the vessel's expected arrival in Tenerife on Sunday 10 May. According to the World Health Organization figures cited by the government on 9 May, eight cases were then linked to the outbreak, with six confirmed and two suspected. One previously suspected case had been ruled out after testing. Three British nationals were among the eight cases.
The British case picture had become clearer by 9 May. Two British nationals had confirmed hantavirus and were receiving hospital care, one in South Africa and one in the Netherlands. A third British national, recorded as a suspected case, had disembarked on Tristan da Cunha, where local health services were monitoring and supporting them. UKHSA and ministers also stressed that none of the other British nationals still on board was reporting symptoms at that stage. That distinction is central to the government's handling of the incident: hospital care for confirmed cases, and controlled repatriation and observation for those without symptoms.
The repatriation model described by ministers is tightly managed. The 8 and 9 May statements said all passengers and crew would undergo further medical checks before disembarkation in Tenerife. British passengers and crew not showing symptoms were then due to be escorted by UK government staff to the airport and placed on a dedicated charter flight arranged by the FCDO. The 8 May statement added that the flight would be limited to British ship passengers and crew and provided free of charge. UKHSA said infection prevention measures would apply from transfer onwards, including face masks and other personal protective equipment, with UKHSA and NHS infectious disease specialists on board to monitor passengers and respond if anyone became unwell.
On arrival in the UK, passengers were due to be moved by dedicated transport to Arrowe Park Hospital on the Wirral. The 9 May statement said returnees would enter a managed setting there for clinical assessment and testing, with public health specialists reviewing each case during an initial 72-hour period. That first assessment window determines the next step. Where living arrangements allow safe isolation, passengers may be permitted to continue isolation at home; where they do not, another suitable location is to be used. UKHSA said all British passengers and crew from the MV Hondius would be asked to isolate for up to 45 days, with monitoring and testing as required.
The wider tracing exercise had already begun before the main repatriation operation. UKHSA said follow-up was under way for people who may have been in contact with cases and had since returned to the UK or were in UK Overseas Territories. Its 6 May update also said two people who had already returned independently to the UK were isolating at home and were not reporting symptoms, while a small number of close contacts were also self-isolating as a precaution. The 8 May statement gave a fuller account of those who had left the ship earlier at St Helena. Seven British nationals had disembarked there on 24 April: two had since returned to the UK independently, four remained in St Helena, and a seventh had been traced outside the UK. The same statement said the Ministry of Defence had worked with UKHSA to send diagnostic supplies, including PCR tests, to Ascension Island on 7 May.
UKHSA's 6 May briefing also set out the medical context. Hantavirus is a group of viruses carried by rodents and spread through exposure to droppings and urine. Human infections are rare and may range from a mild flu-like illness to severe respiratory disease. UKHSA noted that most hantaviruses do not spread easily between people, although person-to-person transmission has been recorded with some strains. That helps explain the consistent public messaging across all three statements. Professor Robin May, UKHSA's Chief Scientific Officer, said established infection control measures would be used at every stage of repatriation, while Dr Meera Chand said tracing and isolation arrangements were being put in place to limit onward transmission. In each update, the government repeated that the risk to the general public remained very low.
The operational picture is one of coordinated public health and consular management. UKHSA was working with the NHS, FCDO, DHSC, WHO, the Home Office and Border Force; UKHSA's 6 May update said WHO was leading the international response and advising on the ship's onward management. The government also referred to cooperation with the cruise operator and the administrations of affected Overseas Territories, while the 8 May statement said a Rapid Deployment Team had been sent from the UK to support the arrangements in Tenerife. For officials, the episode shows how border health control, consular assistance, diagnostics and isolation capacity can be brought together in a single response when an outbreak develops outside the UK but has a direct UK link. For passengers, the practical effect was a sequenced process of screening, escorted transfer, hospital-based assessment and potentially lengthy monitored isolation once back in the UK.
