How fever works How does fever happen? Once endogenous pyrogens have been produced by the primary immune response‚ they must travel to the brain to actually induce fever. After their increased production by activated immune cells‚ cytokines such as IL-1‚ IL-6‚ and TNF are distributed throughout the body through the blood‚ as they are all soluble proteins. Now‚ then‚ these cytokines must have a target to signal and cause a reaction. PGE As it plays a central role in thermal regulation‚ it

dengue hemorrhagic fever‚ a rare complication characterized by high fever‚ damage to lymph and blood vessels‚ bleeding from the nose and gums‚ enlargement of the liver‚ and failure of the circulatory system. The symptoms may progress to massive bleeding‚ shock‚ and death. This is called dengue shock syndrome (DSS). People with weakened immune systems as well as those with a second or subsequent dengue infection are believed to be at greater risk for developing dengue hemorrhagic fever. Diagnosing Dengue

It may also be caused by contaminated water‚ which becomes infected from sewerage.
