Ebola-Like Virus in Iowa: Investigation Underway As Lassa Fever Proves Fatal for Local Man

JOHNSON COUNTY, IA – An Iowa resident returning from a recent trip to West Africa has died from Lassa fever, a rare viral disease with symptoms similar to Ebola. The middle-aged patient, who arrived back in early October, died while receiving treatment in isolation at the University of Iowa Health Care Medical Center.
State and federal health officials, including the Centers for Disease Control and Prevention (CDC), are investigating the case and conducting final lab tests to confirm the diagnosis. Lassa fever cases in the U.S. are exceedingly rare, with only eight previously recorded infections since the 1960s.
A Rare Case with Limited Risk to the Public
Public health officials have confirmed that the patient’s exposure to Lassa fever likely occurred during their travels in West Africa, where the virus is more prevalent. The CDC has assured that there is an extremely low risk of transmission to the public, as the individual did not exhibit symptoms during their travels, greatly reducing the likelihood of spread to fellow passengers or the local community.
Iowa’s Department of Health and Human Services has collaborated with the CDC to monitor people who had close contact with the patient in Iowa. These individuals will be monitored for three weeks, given the virus’s incubation period of 2 to 21 days.
Understanding Lassa Fever: Transmission and Symptoms
Lassa fever is endemic to certain regions of West Africa and is primarily transmitted through exposure to the urine or feces of infected rodents, specifically the West African multimammate rat. These rodents often come into contact with human food supplies, creating a risk for transmission. In rare cases, human-to-human spread occurs, usually through direct contact with bodily fluids, especially among caregivers or family members of infected patients.
The disease presents with a range of symptoms, from mild cases involving fever, weakness, and nausea to severe cases with bleeding, low blood pressure, and even fluid buildup in the lungs. Hearing loss is a noted complication in about a quarter of survivors, though hearing usually improves over time. Treatment includes the antiviral drug ribavirin, which is most effective when administered early in the infection.
Past U.S. Cases and the Limited Risk of Spread
Lassa fever cases in the U.S. are almost exclusively associated with travel to West African regions. The most recent cases before this one occurred in 2016 and 2015, with a 33-year-old nurse contracting the virus while treating an infected patient abroad, and a 55-year-old man succumbing to the illness after working in West Africa. Experts reassure the public that while the virus poses a serious health threat in endemic areas, the risk of domestic outbreaks remains low due to the absence of multimammate rats in the U.S.
Dr. David Hamer, a global health specialist, has noted that human transmission, while possible, has remained rare in the U.S., given the country’s limited exposure to the disease. However, health officials continue to keep a watchful eye on cases like these, mindful of the virus’s potential, albeit low, for spreading within healthcare settings or among close contacts.
The Importance of Vigilance for Travelers
For those traveling to West Africa, public health agencies recommend precautions to reduce the risk of Lassa fever and similar diseases. Avoiding contact with rodents and adhering to safe food storage practices can help travelers minimize exposure. Meanwhile, the CDC is advising healthcare workers and others in contact with the patient to remain vigilant in monitoring their health.
Lassa fever may be rare, but each case underscores the importance of swift response and global awareness in controlling infectious diseases. As the CDC continues its investigation, officials hope to learn from this tragic event and further strengthen public health measures for all travelers.
