Frequently Asked Questions

What exactly is Lassa fever?
Lassa fever's a sneaky virus originating from West Africa. It's spread mainly through contact with food or household items contaminated by rats. Once it gets into humans, it can cause a range of symptoms, from mild to life-threatening.
How does someone catch Lassa fever?
Catching Lassa fever usually happens through exposure to the urine or droppings of infected Mastomys rats. Less commonly, people can catch it from each other, especially in healthcare settings, through direct contact with the blood, urine, feces, or other bodily fluids of someone with the virus.
Are there any specific symptoms to watch out for?
Absolutely. Symptoms start mild, like a fever, general weakness, and headache. As it progresses, more severe symptoms can kick in, such as bleeding from the mouth, nose, vagina, or stomach. Hearing loss is a unique symptom that can occur after recovery.
