Thousands of Americans take these medications
Lassa fever is spread through the feces of infected rats. Additionally, if you are in contact with an infected person's bodily fluids then you could contract the fever.
Bodily fluids of people infected with LASV can be spread through intimate physical contact or exposure to their blood or feces, etc.
Most of those diagnosed with Lassa fever have mild symptoms. However, 20% of people who contract it become extremely ill.
Approximately 100,000 to 300,000 people get Lassa fever in countries in West Africa annually. In the US, there has only been one confirmed death on October 28, 2024.
In mild cases, about one in three people who get Lassa fever has partial or complete hearing loss that may be temporary or even permanent.
For about 20% of people who have Lassa fever, symptoms are things such as chest, neck, or stomach pain, difficulty breathing, severe vomiting or diarrhea, bleeding from the mouth, nose, and eyes, seizures, and confusion.
In cases of pregnant women infected with Lassa fever, over 75% of pregnancies end in the loss of the fetus.
Lassa fever can be diagnosed by testing samples of bodily fluids such as blood or urine, or by a throat swab.
In addition to protecting yourself if you're around someone who is infected, you should also avoid contact with rodents, especially in areas where Lassa fever is prominent.
Doctors and healthcare providers will often treat Lassa fever with ribavirin, which is an antiviral medication. Also, depending on the severity of your condition, other treatments may be prescribed.
Lassa fever can look like other illnesses such as malaria, dengue, and Ebola, so it can be difficult to diagnose. Be sure to tell your doctor if you've traveled lately and might have been exposed to the virus.
It's essential to wear protective coverings when caring for someone who has or might have Lassa fever. This includes a mask, gloves, gowns, non-fogging goggles and boots.
Complications that might occur with Lassa fever include inflammation of the lining around the heart (pericarditis), fluid around the lungs (pleural effusion), infection and inflammation of organs such as the liver (hepatitis), and low platelets (thrombocytopenia).
If you are infected with Lassa virus, you should definitely isolate from others to prevent it from spreading.
In most cases, Lassa fever is mild and it can take a week or longer to feel better. Additionally, about half of people with hearing loss regain hearing within a few weeks.
You should seek out healthcare advice immediately if you begin experiencing symptoms of Lassa fever after visiting countries in West Africa.
If you're having severe symptoms such as chest, neck, or stomach pain or difficulty breathing, severe vomiting, or diarrhea be sure to go to the ER and wear protective gear. Also, alert the staff that you might have Lassa fever.
Remaining in isolation until you're cleared by a medical professional is extremely important. Otherwise, you could be contagious and risk spreading the virus.
If you are diagnosed with Lassa fever, you should ask your doctor for advice about how to prevent spreading the virus, treatment options, and what new or worsening symptoms to look out for.
