What effect do Viral Hemorrhagic Fevers have on the body?

Viral Hemorrhagic Fevers (VHFs) primarily cause blood to seep from tissues and blood vessels due to damage to the vascular system, which can result in bleeding in various parts of the body. This bleeding can manifest both externally, such as through the skin or mucous membranes, and internally, leading to profound complications like organ failure and shock. The underlying mechanism often involves the virus disrupting the endothelial cells that line blood vessels, leading to increased permeability and subsequent leakage of blood components.

While high fever and rash can be associated with some types of VHFs, these symptoms are not as defining as the hemorrhagic manifestations. Respiratory distress can occur in some cases, but it is not the hallmark feature of these fevers. Neurological disorders may arise during some viral infections but are not characteristic of all VHFs. Therefore, the most accurate description of the effects of Viral Hemorrhagic Fevers on the body is the significant bleeding due to vascular disruption, making the statement about blood seeping from tissues and blood vessels the correct choice.
