What is Lassa Fever?
Lassa fever is a viral disease found mainly in Sub-Saharan Africa. It’s caused by the Lassa virus, similar to Ebola. This illness is common in West Africa and takes 2 to 21 days to show symptoms after getting infected.
Viral Hemorrhagic Fever Endemic to West Africa
Lassa fever is a viral disease common in West Africa. Every year, 100,000 to 300,000 cases happen, leading to about 5,000 deaths. The death rate is around 1%, but it can go up to 15% for those who get very sick.
Incubation Period of 2-21 Days After Infection
The time it takes for Lassa fever to show symptoms is 2 to 21 days. During this time, the virus can spread through contact with infected fluids or by touching the multimammate rat. This rat is the main carrier of the virus in West Africa.
“Lassa fever is a serious but treatable viral hemorrhagic fever that is endemic to parts of West Africa. With prompt medical care, the overall fatality rate is about 1%, though it can be higher in severe cases.”
How is Lassa Fever Spread?
Lassa fever is a viral illness mainly spread by contact with infected rodents, like the West African multimammate rat. These rodents carry the Lassa virus and shed it through their saliva, urine, or droppings. Humans get infected by lassa fever transmission when they touch contaminated food, items, or surfaces that have come into contact with these rodents.
Lassa fever can also spread from person to person through contact with infected bodily fluids. When someone is infected, they can pass the virus to others by touching their blood, urine, feces, or other bodily fluids. But, it’s key to remember that person-to-person spread of Lassa fever usually happens after symptoms start. It’s not a highly contagious disease through casual contact.
Transmission Method | Description |
---|---|
Rodent-borne | Exposure to infected West African multimammate rats or their excretions |
Person-to-person | Direct contact with the bodily fluids of an infected individual after the onset of symptoms |
While Lassa fever is a serious illness, it’s not easily spread through casual contact. The Centers for Disease Control and Prevention (CDC) says people with Lassa fever aren’t contagious until symptoms start. This helps limit the spread of the virus.

The iowa lassa fever case highlights the need for caution when traveling to areas with viral hemorrhagic fevers. Even though the risk in Iowa is very low, health officials are keeping a close eye on the situation. They want to make sure everyone stays safe.
Symptoms of Lassa Fever
Lassa fever is a viral disease found in West Africa. It can cause symptoms from mild to severe. In the U.S., it’s rare, with only nine cases since 1969. Knowing the symptoms and severity is key.
Mild Cases: Fever, Fatigue, Headaches
About 8 out of 10 people with Lassa fever have mild symptoms. These include a slight fever, feeling tired, and headaches. These symptoms are similar to many common illnesses.
Severe Cases: Bleeding, Breathing Difficulty, Pain
But, 1 in 5 people can get a severe case. Severe symptoms include bleeding, vomiting, and trouble breathing. You might also see facial swelling and pain in the back, chest, or stomach.
The death rate for Lassa fever is around 1%. But, it can be as high as 15% for those with severe symptoms in the hospital.
The time from getting infected to showing symptoms is usually one to three weeks. Getting medical help quickly is very important. If you’ve been to West Africa and feel sick, see a doctor right away.
Treatment Options for Lassa Fever
For those with Lassa fever, quick and right treatment is key. The main treatment is the antiviral drug ribavirin. It works well against the Lassa virus. It’s best given early, as it can slow the virus and lessen symptoms.
Along with lassa fever treatment with ribavirin, supportive care is vital. This includes rehydration to keep fluids balanced and pain management to ease discomfort. These steps help the body fight the virus and make the patient feel better.
Treatment Approach | Description |
---|---|
Ribavirin Antiviral Therapy | An antiviral medication that has shown effectiveness in treating Lassa fever when administered early in the course of the illness. |
Supportive Care | Includes measures such as rehydration and pain management to support the body’s natural healing process and alleviate symptoms. |
Spotting Lassa fever early and treating it quickly is critical. The disease can get worse fast. With a mix of lassa fever treatment with ribavirin and supportive care, doctors can boost recovery chances for those with this serious illness.
Low Risk to Fellow Travelers
The Iowa resident who recently passed away from Lassa fever was not sick during their travel. This greatly lowers the lassa fever travel risk to others on the plane. State officials say the asymptomatic patient was at an incredibly low transmission risk to others.
Lassa fever is a rare viral disease found in West Africa. It’s very rare for it to spread to the U.S. In the last 55 years, there have been only eight cases linked to travel in the U.S.
Patient Not Sick During Travel
The main reason for the low risk is that the Iowa resident was not sick on the flight. Lassa fever can take 2-21 days to show symptoms. Since the patient was asymptomatic during the flight, the chance of spreading the virus was very low.
The Centers for Disease Control and Prevention (CDC) say the risk to others on the plane is “extremely low.” The virus mainly spreads through contact with infected rodents or their bodily fluids. Person-to-person spread usually requires direct contact with someone’s blood or secretions when they are showing symptoms.
Rare Travel-Associated Cases in the U.S.
Lassa fever is a rare viral hemorrhagic fever found mainly in West Africa. In the United States, cases are very rare. Over 55 years, there have been only eight known cases of travel-related Lassa fever in the U.S.
This disease is not common in the U.S. All previous cases were in people who had traveled to West Africa. The Centers for Disease Control and Prevention (CDC) have recorded only 2,048 cases of travel-associated malaria in the U.S. as of 2019. This shows how rare such travel-related diseases are in the country.
Even though these outbreaks are concerning, the risk of spreading viral hemorrhagic fever in the U.S. is very low. The recent case in Iowa shows that health officials believe the chance of Lassa fever spreading here is very small.
In the rare cases where Lassa fever has been found in the U.S., it has been stopped from spreading. This shows how good public health monitoring and the U.S. medical system are at handling such travel-related diseases.
Monitoring and Investigation Underway
The Iowa Department of Health and Human Services is teaming up with the Centers for Disease Control and Prevention (CDC) and local health groups. They are looking into the Lassa fever case. They are also following public health protocols and checking for anyone who might have been close to the patient.
The CDC says the Iowa person who died had been to West Africa recently. Lassa fever is rare, with a 1% death rate, but it can be severe. About 80% of people don’t show symptoms, but 1 in 5 can get very sick, affecting organs like the liver and kidneys.
The investigation into this Lassa fever case is still going on. Authorities are taking steps to stop the virus from spreading. They are watching the situation closely and looking for anyone who might have been in contact with the patient.
Lassa fever is not common in the U.S., with only 8 cases in 55 years. But the CDC and local health teams are working hard to keep everyone safe. They are monitoring the situation and taking steps to protect the community.
Conclusion
The death of an Iowan from Lassa fever after traveling to West Africa is a wake-up call. It shows how vital it is to be alert and ready for rare diseases. Lassa fever is rare in the U.S., with only nine cases linked to travel in 55 years.
Health officials in Iowa and the U.S. are watching closely and taking steps to prevent more cases. Lassa fever is not usually deadly, with a 1% fatality rate. It spreads mainly through contact with infected rodents in West Africa. Quick treatment with Ribavirin is key to beating the disease.
As our world gets smaller, we must stay ready for diseases like Lassa fever. By researching, educating the public, and working together, we can keep our communities safe. This effort will help protect health and safety in the U.S. and worldwide.
