Viral Hemorrhagic Fevers - Symptoms, Causes, and
Treatment

2
What is Viral Hemorrhagic Fevers?

Viral hemorrhagic fevers are infectious diseases
that could cause severe, life-threatening
diseases. They could damage the walls of tiny
blood vessels, making them leak, and could hamper
the blood's ability to clot. The resulting
internal bleeding is generally not
life-threatening, but the diseases could be.
Some viral hemorrhagic fevers include
Dengue
Ebola
Lassa
Marburg
Yellow fever
These diseases most commonly happen in tropical
areas. In the United States, people who get them
generally have recently traveled to one of those
areas.
There is no cure for viral hemorrhagic fevers.
There are vaccines for only some types. Unless
more vaccines are developed, the most effective
approach is prevention.

Symptoms of Viral Hemorrhagic Fevers

Signs and symptoms of viral hemorrhagic fevers
differ by disease. In general, early signs and
symptoms could include
Fever
Fatigue, weakness, or a general feeling of being
not well
Dizziness
Muscle, bone, or joint aches
Nausea and vomiting
Diarrhea

When should you see a doctor?
The best time to see a doctor is before you
travel to a developing country to make sure that
you have received any available vaccinations and
pre-travel advice for staying healthy.
If you develop signs and symptoms once you return
home, speak to a doctor, preferably one trained
in international medicine or infectious diseases.
Tell your doctor where you have traveled.
Causes
Viral hemorrhagic fevers are spread through
contact with infected animals or insects. The
viruses that cause viral hemorrhagic fevers
reside in a variety of animal and insect hosts.
Most commonly the hosts are mosquitoes, ticks,
rodents, or bats.
Some viral hemorrhagic fevers could also be
spread from person to person.
