Lassa fever remains a serious public health concern, especially in parts of West Africa. Understanding what it is, how it spreads, and how to protect yourself and your loved ones can save lives.
This guide breaks it down simply what causes Lassa fever, what it can do to humans, how to prevent it, and how to care for those affected.
What Is Lassa Fever?
Lassa fever is an acute viral hemorrhagic illness caused by the Lassa virus. It is a zoonotic disease, meaning it spreads from animals to humans, and in some cases, from human to human.
The disease can range from mild symptoms to severe illness, and if not treated early, it can be life‑threatening.

Lassa fever is primarily caused by exposure to the urine or droppings of infected multimammate rats (commonly found in homes and surrounding environments).
- People can become infected through:
- Eating food contaminated with rat urine or droppings.
- Touching contaminated household items or surfaces.
- Poor food storage and hygiene practices.
Common Symptoms Include:
-Fever

Severe Cases May Lead To:
- Bleeding from the mouth, nose, eyes, or other body openings
