Signs of Dengue Fever

Basically signs of dengue fever is start with fever within 6 to 7days after a person has been bitten by an infected mosquito. Then, the temperature drops rapidly and intense sweating takes place. After about a day with normal temperature and a feeling of well-being, the temperature rises abruptly again. Rashes (small red bumps) show up on the arms, legs and the entire body simultaneously along with fever. However, rashes rarely occur on the face. The palms of the hands and soles of the feet may be swollen and bright red. that's the early signs of dengue fever.

Infection with the dengue virus may be subclinical (no apparent symptoms) or may cause illness ranging from a mild fever to a severe, even fatal condition, ie.dengue haemorrhagic fever or dengue shock syndrome.

Fever and other signs of dengue last for two to four days, followed by rapid drop in temperature (defervescence) with profuse sweating. This precedes a period with normal temperature and a sense of well-being that lasts about a day. A second rapid rise in temperature follows. A characteristic rash appears along with the fever and spreads from the extremities to cover the entire body except the face. The palms and soles may be bright red and swollen.

A flat, red rash may appear over most of the body early during the fever. A second rash, measles-like in appearance, appears later in the disease. Infected people may have increased skin sensitivity and are very uncomfortable.

The classic sign of dengue fever lasts about six to seven days, with a smaller peak of fever at the trailing end of the fever (the so-called "biphasic pattern"). Clinically, the platelet count will drop until the patient's temperature is normal.
