These viruses are transmitted to humans by the Aedes aegypti mosquito, a domestic, day-biting mosquito that refers to feed on humans.
Dengue fever is known for having a variety of symptoms all of which happen after a sudden high fever.
The fever ranges from 38.8°C to 40.5°C and it may last for two to seven days.
Undifferentiated fever, accompanied by a rash, is an outcome of dengue infection more common among infants and young children.
Older children and adults are more likely to suffer the classical symptoms of dengue fever include:
*severe headache
*backache
*joint pain
*nausea and vomiting
*mild sore throat
*eye pain
*full body rash, including face, hands and feet
*general weakness
Dengue fever may be confused with Colorado tick fever, typhus, yellow fever, or other hemorrhagic fevers. In dengue fever, leukopenia usually present by the second day of fever.
By the fourth day or fifth day, white blood cells have dropped to 2000-4000/FL, with only 2-40% granulocyte.
The bleeding complications that sometimes accompany classical dengue during epidemics are differentiated clinically from those of dengue hemorrhagic fever.
