Understanding Lassa Virus and Its Transmission
The Lassa virus is a serious disease. It comes from the Arenaviridae family. It is spread by contact with urine or feces of infected rodents. The multimammate rat is a main carrier.
In rare cases, it can spread from person to person. This happens through direct contact with bodily fluids of someone who is sick.
Carried by Rodents, Spread Through Urine and Feces
The main way to get the Lassa virus is through urine or feces of sick rodents. People can get it by touching or eating things that are contaminated. Or by touching infected rodents or their homes.
This disease is common in West Africa. The multimammate rat lives there a lot.
Rare Human-to-Human Transmission Through Bodily Fluids
It’s rare for the Lassa virus to spread from person to person. But it can happen through blood, urine, feces, or other bodily fluids of someone who is sick. This usually happens to healthcare workers or people very close to the sick person.
The recent case of Lassa fever in Iowa shows why we need to know how it spreads. And why we must take steps to stop it from spreading further.
Symptoms and Potential Complications
Lassa fever starts with mild symptoms. These include fever, fatigue, and headache. But, it can get worse, leading to serious problems.
Severe complications can be life-threatening. They include bleeding, breathing troubles, and facial swelling. You might also feel intense pain in your chest, back, and belly. Shock is another serious symptom.
Some people might lose their hearing permanently. This happens in about 30% of cases. Pregnant women are at a high risk of miscarriage.
Mild Symptoms: Fever, Fatigue, and Headache
The first signs of Lassa fever are mild. You might feel feverish, tired, and have a headache. These symptoms are similar to other viral diseases.
Severe Complications: Bleeding, Breathing Difficulties, and Facial Swelling
