“Viral hemorrhagic (hem-uh-RAJ-ik) fevers are infectious diseases that can be life-threatening. They can damage the walls of tiny blood vessels, making them leak. And they can keep the blood from clotting.

Some viral hemorrhagic fevers include:

• Crimean-Congo.
• Dengue.
• Ebola.
• Hantavirus.
• Lassa.
• Marburg.
• Yellow fever.

These diseases most often happen in tropical areas, such as Central Africa. In the United States, most people who get them have traveled to one of those areas.”
