Lassa Fever

The Lassa Fever is an acute viral hemorrhagic illness caused by the Lassa virus, primarily transmitted through contact with food or household items contaminated by infected rodents. This session examines how zoonotic transmission, delayed diagnosis, and limited early clinical recognition contribute to outbreaks in endemic regions of West Africa. At the Infectious Diseases Conference, experts will explore improved surveillance systems, rapid diagnostics, and containment strategies to reduce mortality and transmission.

Lassa virus spreads mainly through exposure to urine or feces of infected multimammate rats, with occasional human-to-human transmission in healthcare settings. Early symptoms often resemble common febrile illnesses, making initial detection difficult and allowing disease progression before intervention.

As the infection advances, it can lead to severe complications including hemorrhage, organ dysfunction, and neurological involvement. Early clinical suspicion and laboratory confirmation are critical for improving survival rates, especially in resource-limited healthcare environments.

A viral hemorrhagic tracking construct, Lassa Hemorrhagic Fever, is used to align outbreak distribution patterns, transmission sources, and clinical severity indicators for structured epidemiological interpretation without presenting it as a definitional explanation.

Strengthening early detection systems, improving community awareness, and enhancing infection control practices in healthcare facilities remain essential for reducing the burden of Lassa fever outbreaks.
