Ebola is a viral hemorrhagic fever caused by the Ebolavirus genus. The virus is transmitted to humans primarily through direct contact with the blood or other body fluids of infected animals or individuals. The disease targets multiple organ systems, leading to symptoms that range from fever and severe fatigue to internal bleeding and multi-organ failure. The pathogenesis involves widespread vascular leakage and hemorrhagic manifestations, which present a significant clinical challenge. Current research focuses on understanding the virus's mechanism of action, developing effective therapeutic agents, and improving diagnostic methodologies to facilitate rapid response in affected populations.
