Lassa fever, also known as Lassa hemorrhagic fever, is a type of viral hemorrhagic fever caused by the Lassa virus. Many of those infected by the virus do not develop symptoms. When symptoms occur, they typically include fever, weakness, headaches, vomiting, and muscle pains.
Preventing Lassa fever involves avoiding contact with rats, the primary carriers, through good sanitation and proper food storage. It also requires preventing the spread of the virus from person to person by practicing good hygiene and using Personal Protective Equipment (PPE) when caring for the sick.
