Viral hemorrhagic fever


Viral hemorrhagic fevers are infectious diseases that interfere with the blood's ability to clot. They damage blood vessels, causing internal bleeding. Examples include dengue and yellow fevers.

These diseases spread by contact with infected animals, people, or insects. Avoiding mosquitoes and rodents can help prevent infection.
