Yesterday, the Centers for Disease Control and Prevention (CDC) issued a travel notice regarding an increased number of cases of Lassa fever.
According to the Nigerian Ministry of Health, there are over 800 suspected cases as of April 13th and over 80 deaths. Seven deaths have been reported among health care workers.
Lassa fever is a viral illness spread by rats and people are infected through direct content with droppings or urine, or by touching objects or consuming contaminated food. Lassa fever is also spread by person-to-person contact through blood, tissue, or bodily fluids.
The symptoms include fever, chest pain, sore throat, back pain, coughing, abdominal pain, vomiting, diarrhea, and bleeding from the mouth or nose. People with Lassa fever also experience hearing loss, tremors, swelling of the face and eyelids and swelling of the brain. When Lassa fever is contracted by a pregnant woman, the symptoms may include bleeding and miscarriage.
The Nigerian government is responding to the outbreak by focusing on disease investigation, patient treatment, and in conducting awareness campaigns among populations who are affected.
Travelers can protect themselves from Lassa fever by following some precautions:
- avoid contact with rats and rat droppings
- store food in rat-proof containers
