Epidemic Investigations of Enteric and Dengue Fever in an Urban Resettlement Area in Dasmariñas, Cavite II. Dengue Studies

An epidemic of typhoid fever occurred in the Bagong Bayan resettlement area in Dasmarinas, Cavite in November 1984 to April 1985. Investigators initially suspected a simultaneous outbreak of dengue fever because several persons were hospitalized with dengue infection 3 months earlier. Of 44 specimens tested only 1 had high IgM ELISA titers indicative of recent dengue infection. The rest of the data did not provide sufficient evidence to conclude that a concurrent dengue outbreak was occurring. However, high IgG ELISA titers in the same specimens confirmed past clinical observations that dengue fever is endemic in the area.
