The Iowa Department of Health and Human Services confirmed on Monday the tragic death of a middle-aged resident from Lassa fever. The individual, who had recently returned from a trip to West Africa, is believed to have contracted the virus during their travels.
What is Lassa Fever?
Lassa fever is a viral disease primarily found in West Africa, where it is spread through contact with the urine or droppings of infected rodents. While common in West Africa, Lassa fever is extremely rare in the United States. In fact, the U.S. has only recorded eight travel-associated cases in the past 55 years, according to the Iowa health department.
The U.S. Centers for Disease Control and Prevention (CDC) is currently working to confirm the diagnosis. Despite the confirmed case, the CDC has stated that the risk to the general public remains very low, as Lassa fever is not easily spread between people.
Impact of Lassa Fever
Lassa fever affects between 100,000 and 300,000 individuals annually in West Africa, with approximately 5,000 deaths each year. While the disease can cause severe illness, it is usually spread through direct contact with infected rodent excretions rather than person-to-person transmission.
A Rare Case in the United States
This tragic case serves as a reminder of the potential health risks associated with international travel, especially to regions where certain diseases are more prevalent. However, with only a handful of cases in the U.S. over several decades, Lassa fever remains a very rare occurrence in the country.
