Advice for Travellers
Lassa fever presents a low risk to most travellers unless they are living in poor sanitary conditions with overcrowding in rural areas where the host is usually found. Lassa fever is a zoonotic viral disease transmitted via the excreta of an infected Mastomys rat. Healthcare workers are at risk if good infection control and barrier nursing methods are not maintained.
Travellers returning from affected areas who develop symptoms of fever, malaise, headache, sore throat, muscle pain, chest pain, nausea, vomiting, diarrhoea, and abdominal pain should seek medical advice.
