What Is Lassa Fever and How Can We Prevent It?

Lassa Fever

Lassa fever is an acute viral hemorrhagic illness caused by the Lassa virus, an arenavirus that is transmitted to humans via contact with infected rodents. It is endemic in parts of West Africa, including Sierra Leone, Liberia, Nigeria, and Guinea. It is estimated that 100,000-300,000 cases occur each year, with thousands of associated deaths.

Signs and Symptoms of Lassa Fever

The incubation period of Lassa fever is between 7 and 21 days. The initial symptoms are similar to the common cold, including fever, headache, nausea, muscle pain, general malaise, and sore throat. However, these symptoms can develop into more serious and life-threatening complications, including respiratory distress, hearing loss, seizures, coma, and death.

The Role of Good Health in Preventing Lassa Fever

Good health is essential in protecting individuals from Lassa fever, as those with compromised immune systems, such as the elderly and those with underlying medical conditions, are at a higher risk of contracting the virus. It is therefore important to maintain a healthy lifestyle that includes a balanced diet and regular exercise, as well as routine check-ups with a healthcare provider. Vaccinations should also be considered for those at risk of Lassa fever.
