Nigeria faces an ongoing battle with Lassa fever,a viral hemorrhagic illness endemic to West Africa. Recent reports indicate a concerning rise in cases and fatalities, underscoring the persistent public health challenge.
Lassa Fever Claims Life of Physician
The Nigeria Center for Disease Control and Prevention (NCDC) confirmed the death of a 31-year-old physician due to Lassa fever. The physician had recently returned from the United Kingdom.
according to a public advisory released on Sunday, the NCDC stated, “On March 5, 2025, the Nigeria Centre for Disease Control and Prevention was notified of a confirmed case of Lassa fever by the Ondo State Ministry of Health. The patient, a 31-year-old physician, was managed at a private health facility in Ondo State after returning from a trip abroad (UK).”
The timeline of events is as follows: “The patient departed Nigeria on 19/02/2025 and returned on 27/02/2025. Samples were taken late on friday, 28/02/2025, on suspicion of Lassa fever, but the patient unluckily passed away in the early hours of Saturday, 01/03/2025.”
Further investigation revealed, “Laboratory investigation confirmed the result as Lassa fever-positive through PCR testing on Tuesday, 04/03/2025. The patient was reported to have visited his fiancée in Edo State, as well as family and friends, before travelling.”
Rising Case Numbers and Geographic Distribution
as of March 2, 2025, the cumulative number of Lassa fever cases has reached 535 out of 2,728 suspected cases, with 98 deaths recorded across 14 states in Nigeria.
The NCDC reports that “as of epi-week 9 (February 24, to March 2, 2025), a total of 2,728 suspected cases, 535 confirmed cases, and 98 deaths have been recorded across 14 states in nigeria, with a case fatality rate of 18.3 per cent.”
The most affected states include:
- Ondo (31 per cent)
- Bauchi (24 per cent)
- edo (17 per cent)
- Taraba (16 per cent)
- Ebonyi (3 per cent)
These five states account for 91% of confirmed cases. Furthermore, ten local government areas contribute to 68% of confirmed cases:
- Owo
- Akure south
- Etsako West
- Kirfi
- Akoko South-West
- Bali
- Esan North-East
- Bauchi
- Toro
- Jalingo
Understanding Lassa Fever
Lassa fever is an acute viral haemorrhagic fever caused by the Lassa virus. The primary reservoir for the virus is the multimammate rat (also known as the African rat), although other rodents can also carry the virus.
Transmission occurs through:
- Direct contact with the urine, faeces, saliva, or blood of infected rodents.
- Ingestion of food or drinks contaminated with the bodily fluids of infected rats.
- Contact with contaminated objects, household items, or surfaces.
- Person-to-person transmission through contact with the bodily fluids of an infected person, notably in healthcare settings with inadequate infection prevention and control practices.
Lassa fever cases occur year-round, with peak transmission periods typically from October to May.
Symptoms and Prevention
Initial symptoms of Lassa fever resemble other common febrile illnesses, such as malaria. These include headache, general body weakness, cough, nausea, vomiting, diarrhoea, muscle pains, chest pain, and sore throat. In severe cases,bleeding from the ears,eyes,nose,mouth,and other body openings may occur.
The NCDC emphasizes that “Early detection, diagnosis, and treatment significantly improve patient survival rates. Prompt reporting of symptoms ensures timely intervention, thereby increasing the chances of survival.”
Control Measures and International Coordination
The Ondo State Ministry of Health has intensified control measures, including contact tracing and listing all individuals who had contact with the confirmed case, to strengthen both national and international coordination efforts.
The NCDC has mobilized all necessary in-country structures to ensure proper monitoring of contacts. Port Health Services are tracing in-flight contacts to bolster surveillance at points of entry, and data has been shared with relevant authorities in line with the International Health Regulations (2005). Contact tracing efforts are also ongoing in the UK.

Frequently asked questions about lassa Fever in Nigeria
What is Lassa fever and why is it a concern in Nigeria?
lassa fever is an acute viral hemorrhagic fever caused by the Lassa virus. It is indeed endemic to West Africa, notably Nigeria, where it poses a notable public health challenge due to its high transmission rate during peak seasons and potential for severe illness and death. The multimammate rat is the primary carrier, leading to human infection through contaminated food, water, and direct contact.
What are the early signs and symptoms of Lassa fever?
The early symptoms of lassa fever are frequently enough non-specific and can mimic those of other common illnesses like malaria, making early diagnosis challenging. these symptoms include:
- Headache
- General body weakness
- Cough
- Nausea
- Vomiting
- Diarrhoea
- Muscle pains
- Chest pain
- Sore throat
How is Lassa fever transmitted?
Lassa fever is primarily transmitted to humans through contact with infected multimammate rats. Specific routes of transmission include:
- Direct contact with the urine, faeces, saliva, or blood of infected rodents.
- Ingestion of food or drinks contaminated with the bodily fluids of infected rats.
- Contact with contaminated objects, household items, or surfaces.
- Person-to-person transmission through contact with the bodily fluids of an infected person, particularly in healthcare settings with inadequate infection control practices.
Which regions or states in Nigeria are most affected by the current lassa fever outbreak?
As of March 2, 2025 (epi-week 9), the most affected states in Nigeria are:
- Ondo (31%)
- Bauchi (24%)
- Edo (17%)
- Taraba (16%)
- Ebonyi (3%)
These five states account for 91% of confirmed Lassa fever cases in Nigeria.
What is the case fatality rate of Lassa fever in Nigeria?
As of March 2, 2025, the case fatality rate (CFR) for Lassa fever in Nigeria is 18.3%.This means that approximately 18 out of every 100 confirmed cases result in death. [Source: NCDC data]
What control measures are being implemented to manage the Lassa fever outbreak in Nigeria?
The NCDC and state ministries of health are implementing several control measures to manage the Lassa fever outbreak,including:
- Contact tracing: identifying and monitoring individuals who have had contact with confirmed cases.
- Laboratory testing: Enhancing diagnostic capacity to confirm suspected cases promptly.
- Risk interaction: Educating the public about Lassa fever prevention and control measures.
- Infection prevention and control (IPC): Improving IPC practices in healthcare settings to prevent person-to-person transmission.
- Rodent control: Implementing measures to reduce the population of multimammate rats in communities.
- International coordination: Collaborating with international organizations and health agencies to share data and coordinate control efforts.
How can Lassa fever be prevented?
lassa fever prevention focuses on minimizing contact with infected rodents and practicing good hygiene.Key prevention measures include:
- Storing food in rodent-proof containers.
- Maintaining a clean household to discourage rodent infestation.
- Disposing of garbage properly.
- Avoiding contact with blood and bodily fluids while caring for sick individuals.
- Implementing strict infection prevention and control measures in healthcare settings.
What is the treatment for Lassa fever?
The primary treatment for Lassa fever is the antiviral drug ribavirin. Early administration of ribavirin is most effective. Supportive care, including fluid management and treatment of secondary infections, is also crucial for managing severe cases.
What is the role of the NCDC in controlling the Lassa fever outbreak?
The Nigeria Centre for Disease Control and Prevention (NCDC) plays a central role in coordinating and implementing measures to control the Lassa fever outbreak. The NCDC’s responsibilities include:
- Surveillance and data collection
- Laboratory diagnosis
- Coordination of response activities
- Risk communication and public education
- Technical assistance to states
- International collaboration
Sharing data in line with the International Health Regulations (2005) is crucial for several reasons:
- Global Health Security: Lassa fever has the potential to spread beyond national borders, which ensures a coordinated global response to prevent and control the disease effectively.
- Early Warning: Timely sharing of data allows other countries to prepare for potential introductions of Lassa fever, especially if they have travelers or close ties with affected regions in Nigeria.
- Compliance: Adhering to the IHR (2005) is a legal obligation for signatory countries, including Nigeria. Following these regulations demonstrates a commitment to international health security and cooperation.
