Investigation Launched in UK After Imported Lassa Fever Case

The UK Health Security Agency is investigating a Lassa fever case imported from Nigeria. An affected individual traveled while symptomatic and was later diagnosed after returning to Nigeria. The public risk is considered very low, as Lassa fever does not spread easily among people. Health officials are reaching out to potential contacts to ensure proper care is provided.

Health officials in the United Kingdom are currently investigating a potential outbreak of Lassa fever following the confirmation of a case linked to recent travel from Nigeria to England. The UK Health Security Agency (UKHSA) reported the case under international notification protocols, indicating that the affected individual traveled while displaying symptoms of the virus.

Upon returning to Nigeria, the individual was officially diagnosed with Lassa fever. In response, the UKHSA is actively working to identify and contact individuals who may have interacted with the infected person during their stay in the UK. Despite the situation, the overall risk to the public remains classified as “very low”, as Lassa fever does not transmit easily between humans.

Lassa fever is endemic to several regions in West Africa, particularly Guinea, Liberia, Nigeria, and Sierra Leone. The virus is primarily carried by the Mastomys rodent and is typically contracted through consumption of contaminated food, inhalation of the virus, or contact with rodent droppings. In less common instances, the virus may spread through bodily fluids such as blood or saliva.

Most individuals infected with the virus experience mild symptoms, including fever, weakness, headache, and sore throat. Serious manifestations can involve bleeding, difficulty breathing, and abdominal pain. Dr. Meera Chand, deputy director at UKHSA, emphasized that the agency’s health protection teams are urgently reaching out to those who may have been in contact with the traveler to ensure they have access to medical care, if necessary. Symptoms generally arise within one to three weeks following exposure to the virus.

In conclusion, the UK faces a potential Lassa fever case linked to recent travel from Nigeria. While health officials are taking precautionary measures to identify contacts, the risk of widespread transmission is considered low. Continued vigilance and public health coordination remain essential in managing this situation.
