Viral hemorrhagic fevers (hem-uh-RAJ-ik) are infectious diseases that can cause serious and potentially fatal diseases. They can damage the walls of tiny blood vessels, cause them to leak and affect the blood’s ability to clot. The resulting internal bleeding is usually not fatal, but it can be a disease.

Some viral hemorrhagic fevers include:
- Dengue fever
- Yellow fever
The signs and symptoms of viral hemorrhagic fever vary depending on the illness. In general, the first signs and symptoms can include:
- Tiredness, weakness or generally feeling unwell
- Muscle, bone or joint pain
- Nausea and vomiting
Viral hemorrhagic fever spreads through contact with infected animals or insects. The viruses that cause viral hemorrhagic fever live in a wide variety of animal and insect hosts. The hosts usually include mosquitoes, ticks, rodents or bats.
Some viral hemorrhagic fevers can also spread from person to person.
How is it transmitted?
Some viral hemorrhagic fevers are transmitted through mosquito or tick bites. Others spread through contact with infected body fluids such as blood, saliva, or semen. Some varieties can be inhaled from infected rat feces or urine.
If you travel to an area where a particular hemorrhagic fever is common, you may be infected there but not develop symptoms until you return. Depending on the type of virus, it can take two to 21 days for symptoms to develop. Lassa fever Treatment in Hyderabad
