The study had been revised and made a new application.

Originally test host's to understand the tracking healthily and immune change of the dengue fever in Taiwan. Blood drawing 20 c.c for liver examination, kidney and other biochemical function, analyze host immunity adjusts and controls the gene, and the reciprocation that may be produced with the virus hepatitis, besides collected 10 c.c urine at the same time. Urine check is in order to compare acute infect and infected over three month person, the change of chemical composition.

This plan expect to collect 150 healthy, 150 dengue fever infected and 150 dengue fever bleed hot or dengue fever shock disease group's patient, goal to understand health state and immunity of follow-up adjust and control the difference of the gene and the reciprocation may produce to virus hepatitis of light disease and serious disease.

The dengue fever is an important tropical infectious disease in the south of Taiwan, cause and threaten of public health at Kaohsiung and Ping-Dong all over the years, this will cause patient's death, the default of clinical change of dengue fever, acute infect, infect influence, host immunity adjust and control, and the reciprocation of virus hepatitis, will be a very urgent in basic research.

Urine check is in order to compare acute infect and infected over three month person, the change of chemical composition. The result of study can help doctor to understand the factor of immune regulation and control of the host and health change after the dengue fever is infected with, possible reciprocation with virus hepatitis. Researchers have collect 100 dengue fever bleed hot or dengue fever shock syndrome groups of patient, it is estimated that can collect and expect the case will be counted within two years.

Inclusion Criteria:

• Clinical diagnosis of Dengue Fever

The patients who are suspicious of dengue infection.
