You are a doctor working in sierra leone. a patient presents with fever, vomiting, bleeding and a brain infection. which would be best to diagnose?

I would diagnose the patient with lassa fever. Lassa fever is an acute viral illness which lasts for 4 weeks. It occurs mostly in west Africa and Sierra leone is found in west Africa. Some of it's symptoms are fever, nausea or vomiting, headache and diarrhea. In severe cases bleeding will occur.
