Lassa fever is a viral illness that is common in parts of West Africa, including Nigeria. It is caused by the Lassa virus, which is transmitted to humans through contact with food or household items contaminated by infected rodent urine or feces, specifically the Multimammate rat. In some cases, the virus can also spread between humans through direct contact with an infected person’s bodily fluids. Understanding the symptoms of Lassa fever and how it spreads can help you recognize the illness early and seek prompt medical attention.
Causes of Lassa Fever
Lassa fever is primarily caused by the Lassa virus, which is transmitted to humans through exposure to infected Mastomys rats. These rats are commonly found in parts of West Africa, and their urine or droppings can contaminate food, water, or surfaces. While the virus is mainly spread by rodents, it can also spread between humans through contact with bodily fluids such as blood, urine, or saliva of an infected person.
The risk of Lassa fever is higher in rural areas where these rodents are common, especially in homes where food is not properly stored or hygiene practices are poor. People working in healthcare facilities are also at risk if they come into contact with infected patients without proper protective measures.
Symptoms of Lassa Fever
Lassa fever symptoms can vary greatly, ranging from mild to severe, and in some cases, it can be fatal. In many cases, people infected with the Lassa virus may not show any symptoms at all, or they may experience mild symptoms that resemble the flu. However, in more severe cases, Lassa fever can cause life-threatening complications.
Here are the common symptoms of Lassa fever:
- Fever: One of the first signs of Lassa fever is a high fever that can last several days.
- Headache: Persistent headaches are common and can be severe.
- Sore throat: Some individuals may experience a sore or scratchy throat, which may make swallowing difficult.
- Muscle pain: General muscle aches and joint pains are common symptoms of Lassa fever.
- Nausea and vomiting: Gastrointestinal symptoms like nausea, vomiting, and abdominal pain may occur.
- Weakness: Extreme fatigue and weakness are often reported by those infected.
- Cough: A persistent cough may develop, especially in more advanced cases.
- Chest pain: Some individuals may experience pain or discomfort in their chest, which can worsen as the illness progresses.
- Hearing loss: In some severe cases, temporary or permanent hearing loss may occur, even after the fever subsides.
- Bleeding: In a small percentage of cases, individuals with Lassa fever may experience bleeding from the mouth, nose, eyes, or other body parts. This is a sign of a severe infection and requires immediate medical attention.
Complications of Lassa Fever
Lassa fever can lead to serious health complications, especially if left untreated. These complications may include:
- Organ failure: In severe cases, Lassa fever can cause damage to the liver, kidneys, or spleen, leading to organ failure.
- Severe bleeding: Although rare, some individuals may experience severe internal or external bleeding.
- Neurological problems: Lassa fever can affect the nervous system, leading to confusion, disorientation, or seizures.
Without prompt treatment, Lassa fever can be fatal, particularly for pregnant women and individuals with weakened immune systems. Approximately 1% of those infected with Lassa fever die from the illness, but early detection and treatment can significantly improve the chances of recovery.

It is important to seek medical care as soon as possible, especially if you have been exposed to the virus or are showing symptoms. The earlier the treatment is started, the better the outcome.
Preventing Lassa Fever
Preventing Lassa fever involves reducing contact with the rodents that carry the virus. Here are some key prevention tips:
- Store food properly: Keep food in rodent-proof containers and maintain clean living areas to reduce the risk of contamination by rodents.
- Good hygiene: Wash your hands regularly with soap and water, especially before eating or after handling food.
- Rodent control: Use proper pest control methods to keep rodents out of homes and workplaces.
- Avoid contact with infected individuals: If you are caring for someone with Lassa fever, take precautions to avoid contact with their bodily fluids, and ensure that you are using protective equipment like gloves and masks.
