An Iowa resident is dead after contracting a suspected case of Lassa fever in West Africa earlier this month, the CDC said. Here's what you need to know.
What is Lassa fever?
Lassa fever is an acute viral hemorrhagic illness caused by the Lassa virus, primarily spread by rats found in West Africa. It is potentially life-threatening and can lead to severe symptoms in infected individuals.
How is Lassa fever spread?
Lassa fever spreads through contact with the urine or droppings of contaminated rats or infected individuals' bodily fluids. It's not airborne, meaning casual contact without exposure to fluids does not pose a risk.
What are the symptoms of Lassa fever?
Symptoms typically develop one to three weeks after infection and can range from mild fever and tiredness to severe bleeding and respiratory distress. About 20% of cases lead to serious symptoms.
How is Lassa fever treated?
Patients can receive Ribavirin, an antiviral drug that is most effective when administered early in the illness. Supportive care such as hydration and symptom management is also recommended.
Tips for preventing Lassa fever
There are no vaccines available. Preventive measures include avoiding contact with rats, storing food properly, and maintaining cleanliness in areas where food is stored.
