What is the Philippine Department of Health's (DOH) intervention for Dengue fever, considering equity lens PROGRESS (Place of residence, Race/ethnicity, Occupation, Gender, Religion, Education, Socioeconomic status, and Social capital)?

Philippine Department of Health Dengue Interventions Through an Equity Lens (PROGRESS Framework)

The Philippine Department of Health has implemented community-based dengue vector control programs that combine environmental management, social mobilization, and biological control methods, but these interventions face significant equity challenges across the PROGRESS dimensions—particularly affecting informal settler communities who lack continuous piped water supply, have limited health literacy, and experience barriers to sustained behavior change. 1

Overview of Philippine Dengue Control Strategies

The Philippines employs an integrated vector management approach that includes:

• Larval source reduction through household water container management, targeting the primary breeding sites of Aedes aegypti in residential areas 2, 1
• Biological control using Bacillus thuringiensis israelensis (VectoBac DT/Culinex Tab tablets) in water containers, which maintains 100% larval mortality for 18-30 days in sun-exposed containers and 30-36 days in shaded containers 2
• Community mobilization delivered through local health workers (Barangay Health Workers/BHWs) and dengue control personnel 1
• Malaria early warning systems that have been adapted for dengue outbreak preparedness 3

Equity Analysis Using PROGRESS Framework

Place of Residence

Urban informal settlements face the most severe dengue burden and intervention barriers. 1

• Metropolitan Manila communities are socially and economically diverse, with city governments struggling to provide basic services like continuously available piped water supply 1
• Informal settler communities (Village B in studies) show markedly different intervention uptake compared to gated communities (Village A), with water storage practices driven by necessity rather than choice 1
• Cemeteries show predominance of Aedes albopictus, while residential areas harbor Aedes aegypti as the principal container breeder, requiring location-specific strategies 4
• Discarded tires have the highest infestation rate (69.4%), concentrated in lower-income neighborhoods with inadequate waste management 2

Race/Ethnicity

The available evidence does not specifically address ethnic disparities within the Philippines, though indigenous populations and minorities typically experience the highest degree of socio-economic marginalization and are therefore most vulnerable to vector-borne diseases. 3

Occupation

Occupational patterns create differential dengue exposure risks. 3

• Women face increased risk based on housekeeping roles in the domestic habitat where Aedes vector densities are highest and stable year-round 3
• Men may have increased risk based on outdoor occupations, though Aedes aegypti is primarily a domestic vector in Philippine urban settings 4
• Indoor resting collections show low Aedes aegypti populations during the dry season (February-May) and higher populations during rainy season (June-September), affecting outdoor workers differently 4

Gender

Gender roles significantly influence dengue prevention practices and intervention success. 3

• Women's domestic responsibilities place them at higher risk in households where flower vases (the most common indoor larval habitat) and water storage containers are maintained 2, 4
• Community-based interventions rely heavily on household-level behavior change, which disproportionately depends on women's labor and compliance 1

Religion

The evidence does not provide specific data on religious factors affecting dengue interventions in the Philippines, though religion is recognized as a dimension influencing vulnerability to vector-borne diseases. 3

Education

Health literacy gaps severely limit intervention effectiveness. 5

• Only 68.7% of surveyed Filipinos were aware that dengue is transmitted by mosquitoes, and merely 4.3% knew that a virus causes the disease 2
• Meta-analysis of 15 Philippine dengue studies (2000-2020) revealed poor mean scores for knowledge (68.89), attitude (49.86), and preventive practice (64.69) 5
• Worryingly, 95% of respondents showed negative attitudes toward dengue prevention, claiming prevention was not possible and that enacting preventive practices was not their responsibility 5
• Television and radio were the main sources of dengue information (50-95% of respondents), indicating reliance on mass media rather than direct health education 5

Socioeconomic Status

Poverty creates the most profound barriers to dengue prevention and control. 3, 6, 1

• Informal settler communities lack continuous piped water supply, necessitating water storage in containers that become Aedes breeding sites—a poverty-driven risk factor 1
• Low socioeconomic status translates into limited political access, reducing availability of key resources and opportunities for effective vector control 3
• Metal or glass containers were the most common outdoor larval habitats, reflecting material constraints in lower-income households 4
• The World Health Organization notes that validated prevention and control tools exist but lack sufficient political will and funding for scale-up in developing regions like the Philippines 6

Social Capital

Community organization and trust determine intervention sustainability. 3, 1

• Behavioral change frameworks reveal that the social nature of urban communities is often overlooked when dengue control programs introduce new interventions 1
• The Cuban experience demonstrates that scaling-up community empowerment approaches faces resistance from top-down organizational structures, with insufficient dissemination to decision-makers and misinterpretation of empowerment principles 3
• Sustained government investment and support are essential to provide oversight, capacity building, and guidance to local residents and grassroots NGOs attempting to maintain activities over time 3
• Multi-sectoral collaboration between ministries, nonprofit groups, schools, and health centers is necessary but challenging to establish and maintain 3

Critical Gaps and Recommendations

Enhanced surveillance and early warning systems must integrate socioeconomic factors alongside climate data. 3

• Predictive models and early warning systems should integrate climate and meteorological factors with socioeconomic variations, land use changes, urbanization, and population growth to accurately predict disease emergence 3
• Only 50% of 101 surveyed countries had developed national health and climate change strategies, with merely 9% reporting funds to fully implement their plans 3

Community participation requires structural changes, not just education. 3

• The Asian Development Bank and WHO Western Pacific Region demonstration project (2009-2011) using guppy fish distribution combined with environmental control and social mobilization reduced larval infestation from 40% to 3%, but required sustained multi-sectoral collaboration 3
• Integrated vector management requires strong community participation and support from multiple actors including community-based groups, NGOs, research institutes, and different government departments 3

Common Pitfalls to Avoid

• Do not assume health education alone will change behavior when structural barriers like lack of piped water supply force communities to store water in containers 1
• Do not implement one-size-fits-all interventions without understanding site specificities, social-ecological context, local livelihoods, and political nuances 3
• Do not neglect the importance of sustained government investment in maintaining biological control distribution systems and community mobilization efforts 3
• Do not overlook the organizational resistance within existing dengue control programs when attempting to introduce participatory, empowerment-based approaches 3
• Do not rely solely on biomedical tools without addressing the social determinants of health including water access, housing quality, waste management, and poverty 3, 6
