The UK Health Security Agency (UKHSA) says three cases of Lassa fever have been recorded in the country.
Lassa fever is an acute viral haemorrhagic illness caused by the Lassa virus. People usually become infected with the Lassa virus through exposure to food or household items contaminated with urine or faeces of infected rodents – present in a number of West African countries where the disease is endemic.
The virus can also be spread through infected bodily fluids.
Most people with Lassa fever will make a full recovery, however severe illness can occur in some individuals.
In a statement earlier this week, the agency had announced that two people had been diagnosed with the disease in the country.
It had said a probable case of Lassa fever was under investigation.
The agency also added that the cases were within the same family and are “linked to recent travel to West Africa”.
