CDC releases new details on rare Lassa fever case in Iowa
Case highlights the importance of being vigilant against imported infectious diseases
The Centers for Disease Control and Prevention (CDC) has released more information about the case of Lassa fever that was identified in Iowa earlier this month. The patient, a resident of Nigeria, is currently being treated in isolation at a hospital in Nebraska. This is the first case of Lassa fever to be diagnosed in the United States in more than a decade.
What is Lassa fever?
Lassa fever is a viral hemorrhagic fever that is endemic to West Africa. The virus is transmitted to humans through contact with the urine or feces of infected rodents. Symptoms of Lassa fever can range from mild to severe and include fever, headache, muscle aches, nausea, vomiting, and diarrhea. In severe cases, Lassa fever can lead to organ failure and death.
How is Lassa fever treated?
There is no specific treatment for Lassa fever. Treatment is supportive and includes measures to prevent dehydration and electrolyte imbalance. Ribavirin, an antiviral medication, may be used to treat severe cases of Lassa fever. However, the effectiveness of ribavirin is not well-established.
What is the risk of Lassa fever in the United States?
The risk of Lassa fever in the United States is very low. However, the CDC recommends that healthcare providers be aware of the symptoms of Lassa fever and take precautions to prevent infection. Healthcare providers should also be aware of the potential for Lassa fever in patients who have recently traveled to West Africa.
What is the CDC doing to respond to the Lassa fever case in Iowa?
The CDC is working with state and local health officials to investigate the case of Lassa fever in Iowa. The CDC is also providing guidance to healthcare providers and the public on how to prevent and treat Lassa fever. The CDC is also working with international partners to strengthen surveillance and response efforts for Lassa fever in West Africa.
What can you do to protect yourself from Lassa fever?
There are a number of things you can do to protect yourself from Lassa fever, including:
- Avoiding contact with rodents and their urine and feces
- Washing your hands frequently with soap and water
- Eating only cooked food
- Drinking only clean water
- Seeking medical attention if you develop symptoms of Lassa fever
