We understand that a high risk contact in Ascension has developed symptoms consistent with hantavirus. Initial testing for hantavirus was negative, from samples shipped to the United Kingdom, but further investigations are ongoing.
We also understand that a family member of this contact travelled to St Helena on Sunday 10 May 2026. This family member is not suspected to have been infected with hantavirus but has been asked to enter isolation as a precaution until the full testing results and details of the situation are confirmed. There is currently no indication of any additional risk to the wider population in St Helena as a result of this development.
This individual is part of a group of medical personnel on Ascension Island who had close contact with a confirmed case and had already been assessed as higher risk. As a precaution, plans are in place for their relocation. These arrangements are being kept under review to ensure they can respond to any change in clinical circumstances.
