What is it: Lassa fever is an acute viral illness
that occurs in West Africa. It is highly contagious and
occurs mainly in the dry season in West Africa,
particularly Guinea, Liberia, Nigeria, Sierra Leone, and
the DRC.

How do I get it: Rodents shed the virus in urine
and droppings which means that the virus can be transmitted
through direct contact with these materials, through
touching objects or eating food contaminated with these
materials, or through cuts or sores.

What happens if I get it: Symptoms of Lassa Fever
typically occur 1-3 weeks after the patient comes into
contact with the virus. These include: fever, pain behind
the chest wall, sore throat, back pain, cough, abdominal
pain, vomiting, diarrhoea and a rash. After four weeks
occur: bleeding, ascites and shock. Death occurs in 50 % of
patients.

Diagnose and treatment: the virus can be detected
in blood and urine. The anti-viral agent Ribavarin can be
used, otherwise it is a question of symptom control and
intensive care.

How can I avoid contracting Lassa fever: avoid
contact with rodents.
