Viral hemorrhagic diseases are severe illnesses caused by specific viruses that lead to bleeding and organ failure. These diseases can be transmitted through direct contact with infected bodily fluids, contaminated surfaces, or vectors like mosquitoes. Common examples include Ebola, Marburg, and Dengue fever. Symptoms often include fever, fatigue, and bleeding from various body parts. The severity of these diseases can vary, with some leading to high mortality rates. Prevention strategies focus on avoiding contact with infected individuals and improving sanitation practices to reduce the risk of outbreaks.
