Even after the height of the epidemic, one hundred children at Duren Sawit Junior High School in East Jakarta were still part of a prevention programme called "3M" (Menguras, Mengubur, Menutup), means: to clean the environment, to bury waste and to cover water at and around schools – all to take away the breeding habitat of the day-biting mosquito.

Abate, an insecticide, was poured into water in areas where water was scarce and had to be stored.

Many of those affected by the acute onset fever associated with DHF were children. The public hospital is one of the some which have been fully booked by dengue patients. (Name of patients unknown).The PMI hospital based in Bogor also handled DHF patients. Hospitals were so overloaded that a meeting room became the emergency room.
