The public are advised that the Health and Social Care Portfolio have become aware of an evolving situation regarding a severe illness, affecting several passengers on the expedition vessel MV Hondius which recently visited St Helena between 22-24 April 2026.
The suspected cause is hantavirus, which is usually spread through contact with infected rodents, but may eventually pass from person-to-person. Symptoms can include fever, extreme fatigue (feeling more tired than usual), muscle aches, stomach pain, nausea, vomiting, diarrhoea or shortness of breath. Some people may develop severe breathing difficulty requiring hospital care.
Two passengers with minor symptoms came ashore and may have had some contact with members of our local community.
While the virus can be serious, no cases of this illness have been identified in St Helena and there is no significant cause for concern on the island at this time.
Public Health is working closely with the United Kingdom Health Security Agency (UKHSA) and other international partners to assess and manage the situation. A small number of people who travelled to St Helena on the MV Hondius or had very close contact with those who were showing symptoms, are being advised by Public Health to undertake a period of self-isolation as a precaution. St Helena Government (SHG) will provide full support to those who are asked to do so. A full risk-based contact tracing process is underway to identify and notify such persons.
The risk to the wider community is low and no additional precautions are necessary at this time. However out of the abundance of caution, should you experience a significant fever (>38°C), then you should contact the hospital on tele No 22500 for advice, but please DO NOT attend in person at the first instance.

The public are thanked for their support and cooperation during this time. Further updates will be provided on a regular basis.
