Lassa Fever: A Hidden Threat in West Africa

A lesser-known but potentially deadly virus lurks in West Africa. Here's what you need to know about Lassa fever.
Lassa fever, a viral hemorrhagic fever, has been plaguing West Africa for decades, yet it remains relatively unknown outside the region. Caused by the Lassa virus, this disease takes its name from the town in Nigeria where it was first identified in 1969.
Like many other viral hemorrhagic fevers, Lassa fever is primarily spread through contact with infected rodents. These agile creatures, often found in homes and granaries, shed the virus in their urine and feces. If humans come into contact with these contaminated substances, they risk contracting the virus.
The symptoms of Lassa fever can vary depending on the severity of the infection. In mild cases, people may experience flu-like symptoms such as fever, headache, and muscle pain. However, in more severe cases, the virus can lead to internal bleeding, organ failure, and even death.
Transmission of Lassa fever from human to human also occurs, posing a significant risk for healthcare workers and family members caring for infected individuals. The virus can be passed on through bodily fluids such as blood, vomit, or feces.
The prevention of Lassa fever primarily focuses on rodent control and maintaining good hygiene. Keeping homes and food storage areas clean and free from rodents is essential. Hand washing, using disinfectants, and avoiding contact with potential sources of infection are also recommended.
Although Lassa fever may not be as well-known as other viral hemorrhagic fevers, its impact on the health and lives of people in West Africa is significant. Raising awareness about the disease, implementing preventive measures, and ensuring timely diagnosis and treatment are crucial steps towards combating this hidden threat.
