Investigation Launched in UK Following Lassa Fever Case from Nigeria

The UK Health Security Agency is investigating a confirmed case of Lassa fever from an individual traveling from Nigeria. The overall risk to the public is very low, though efforts are underway to trace contacts. Lassa fever primarily spreads through rodents and has mild to severe symptoms, requiring prompt medical attention if exposure occurs.

Health officials in the United Kingdom are currently investigating a potential outbreak of Lassa fever, after identifying an infected individual who traveled to England from Nigeria. The UK Health Security Agency (UKHSA) reported that the individual was unwell with Lassa fever during their journey and subsequently returned to Nigeria for diagnosis. In response, the UKHSA is actively working to trace contacts that the affected person had while in the UK.

Despite the confirmed case, the risk of widespread transmission is considered to be very low, as Lassa fever does not spread easily between individuals. The virus is endemic in several West African nations, including Guinea, Liberia, Nigeria, and Sierra Leone, and is primarily transmitted to humans through contact with the Mastomys rodent or contaminated food and surfaces. Furthermore, human transmission may occur through bodily fluids such as blood, saliva, urine, or semen, albeit rarely.

Many cases of Lassa fever result in mild symptoms, such as fever, weakness, headache, and sore throat, and patients typically recover. In contrast, more severe symptoms can include bleeding, breathing difficulties, vomiting, and facial swelling. Dr. Meera Chand, deputy director at UKHSA, confirmed that health protection teams are urgently contacting individuals exposed to the infected person to facilitate appropriate medical care and testing if symptoms arise. Symptoms generally manifest within one to three weeks following exposure to the virus.

In summary, the UK is alerting the public about a potential case of Lassa fever following an individual’s recent travel from Nigeria. Although the virus is serious, the likelihood of person-to-person transmission is minimal, and health authorities are taking proactive measures to ensure public safety. Continued monitoring and communication will be essential in managing this situation effectively.
