Prevention is Primary!Prevention is Primary!

Widespread Disease• Some 50 million cases of dengue

infection every year, and the disease is now endemic in more than 100 countries (South-east Asia and the Western Pacific are most seriously affected)

The Rise in Dengue Cases

Previous Observations• Dengue fever (DF) and dengue haemorrhagic

fever (DHF) are endemic in all regions of the Philippines, with epidemics occurring every 3-4 years.

• The area with the highest morbidity and mortality are urban centres such as Metro Manila, Cebu, Davao, etc.

• Dengue occurs throughout the year, with rates increasing one-to-two months after the onset of the rainy season in June.

• The largest number of cases recorded in recent years was in 1998 when a nationwide dengue epidemic was declared, with a total of 36 162 cases and 514 deaths reported.

• In 2001, after two years with low incidence of dengue, another outbreak occurred with 25 216 cases and 177 deaths. Since 2001, the annual number of cases has remained high.

• All four dengue virus serotypes are present in the Philippines, although DEN 1, DEN 2 and DEN 3 are predominant.

• Children under 15 years account for about 75% of all cases, and the majority of the fatal cases occur among children below the age of nine. Males and females are equally affected.

Surveillance and response

• Dengue is a notifiable disease in the Philippines, and cases and deaths are reported from hospitals through a sentinel reporting system known as the National Epidemic Sentinel Surveillance System.

• A very small proportion of the reported cases are laboratory confirmed. Until 2004, the surveillance system reported only total number of dengue cases and deaths from hospitals.

• However, as of 2005, standardized surveillance case definitions for DF and DHF have been implemented nationwide, and DF and DHS/DSS cases are now reported separately.

• The National Dengue Prevention and Control Programme (NDPCP) under the Infectious Disease Office of the Department of Health emphasizes mosquito control using larval source reduction, through community participation. However, insecticide fogging for adult control is still frequently used.

Surveillance and response

Community mobilization• The national dengue control programme has a

supervisory role due to the devolution of health services, and provides training and education through different approaches.

• The Department of Health has produced a number of training materials, but limited funds to print sufficient copies of this for the needs of the country.

• According to many public health professionals, the understanding of the general population about dengue is quite good, but it is difficult to overcome the inertia as regards to solid waste disposal.

• One fundamental factor in this is that the national capital region with a population of more than 12 million and a sharp division into a number of municipalities has not been able to establish an adequate public waste disposal system.

• Other municipalities in the country have been able to provide better leadership for dengue control. In the capital region, the most effective community organization for dengue control is led by Rotary Clubs, which have involved a large number of nongovernmental organizations.
