Dengue fever and dengue hemorrhagic fever (also known as break-bone fever) are acute febrile diseases which may be severe and potentially deadly if not treated immediately. Disease transmission is through the Aedes Aegypti mosquito. Presently, there are four different viruses known to cause dengue hemorrhagic fever to humans.

The dengue patient may experience irritation, restlessness, sweating, severe headache, muscle and joint pains, fever, petechial rash, and ecchymosis.

There is still no known cure or vaccine for dengue. Treatments available are increase fluid intake and administration of IV fluids and electrolytes to correct electrolyte imbalances and dehydration, oxygen therapy to treat abnormal low blood oxygen, and transfusion of fresh blood or platelets to correct the bleeding problems. Rest is important for dengue patients. For severe headache and joint and muscle pains, Acetaminophen and codeine may be given. Aspirin and non-steroidal anti-inflammatory drugs should be avoided to avoid bleeding problems.
