The UK Health Security Agency (UKHSA) has advised anyone who has had direct or household contact with a confirmed case to isolate for 21 days.
Contacts have also been issued guidance to provide details for contact tracing, cease travelling and avoid contact with immunosuppressed people, pregnant women, and children under 12.
Dr Susan Hopkins from the UKHSA confirmed that the agency has detected cases which have no contact with anyone who has visited West Africa, where the disease is endemic.
