The Ward With the Water Drums
Ward 7 of a coastal panchayat in Alappuzha has 1,240 households. Piped water is supplied for about 45 minutes every alternate day. Many families store water in open plastic drums and cement tanks; a survey found 38% of households with at least one open container. Over three weeks, 14 confirmed dengue cases were reported, including 5 children under 12. The nearest PHC is 6 km away. The panchayat has done one fogging round and distributed a leaflet in Malayalam. Residents say fogging 'kills the mosquitoes' and do not empty containers. There is also solid waste dumped along a canal, and 22% of households have no toilet. The ASHA worker has 10 days and a small budget of ₹5,000 to organise an extension campaign before the next health inspection.
1. Identify the key environmental and behavioural factors maintaining the dengue risk in Ward 7. Which two should the campaign address first, and why?
Read the worked answer
Environmental factors: intermittent piped supply forces household storage; 38% of households have open containers; solid waste along the canal provides additional breeding sites; 22% without toilets creates a separate sanitation and health burden.
Behavioural factors: the belief that fogging alone 'kills the mosquitoes'; failure to empty and scrub containers; low risk perception; possibly storing more water than needed.
Prioritise two: (1) open stored-water containers, and (2) the fogging misconception. Aedes aegypti, the main dengue vector, breeds in clean water in domestic containers. Fogging kills adult mosquitoes temporarily and does not remove larvae or eggs, so it creates false security. Source reduction by covering, scrubbing and weekly emptying is the sustainable intervention. Waste along the canal is also important, but it is secondary for dengue compared with domestic containers. The missing toilets are a serious sanitation issue, but they should not displace the container campaign in a 10-day dengue response.
2. Design a 10-day campaign with a clear message, two channels, and a community activity. Explain how you would involve local institutions and how you would measure success.

Message: 'Once a week, empty, scrub and dry every water container; keep stored water covered.' The Malayalam version should be short enough for wall painting and household cards.
Channels: (1) household visits by ASHA/volunteers with a simple checklist; (2) ward WhatsApp group, local announcements and a school assembly. Add a street play at the market junction.
10-day plan: Days 1–2: baseline check of 100 households and mapping of containers; meet the ward member, Kudumbashree and school head. Day 3: launch with a school assembly and announcement. Days 4–8: house visits, demonstrations of scrubbing and covering, and distribution of stickers. Day 9: community 'Dry Day' clean-up of the canal waste and a container-emptying drive. Day 10: repeat the 100-household check and give feedback at the ward meeting.
Institutions: Kudumbashree neighbourhood groups for household reach, schools for children as messengers, local clubs and religious leaders for legitimacy, and the ward member for logistics and follow-up.
Success measures: percentage of sampled households with open containers before and after; number of containers emptied or covered; presence of larvae in a sample of 20 containers; reported cases in the next three weeks; attendance at the clean-up. Budget: about ₹1,500 printing, ₹1,000 scrubbers/gloves, ₹1,000 refreshments for volunteers, ₹1,500 contingency.
3. A resident says, 'We have no choice-water comes only every other day, so we must keep drums open.' How should the extension worker respond without blaming the family? Give a practical, low-cost solution and a negotiation step with the panchayat.

Response: acknowledge the real constraint first: 'You are right that the supply is unreliable, and storing water is necessary. The risk is not storage itself; it is open storage.' This avoids blaming the family and keeps the conversation on solutions.
Practical low-cost solution: use a tight lid or tie a fine cloth/mosquito net over the drum; draw water with a ladle or tap rather than dipping hands and cups; scrub the inner walls weekly and dry the container in sunlight; store only two days' need where possible; keep cement tanks covered and check for gaps.
Negotiation with the panchayat: take the survey data and a written request to the ward meeting. Ask for a fixed supply schedule, repair of leaks, and a covered community storage tank. Propose that the ward fund a lid distribution or a drum-covering demonstration. Present the dengue cases and the 38% open-container figure as a shared problem, not an accusation.
Follow-up: report back to residents within a week and repeat the container check. The worker's role is to make the safe option feasible, not to demand behaviour change while ignoring the water supply.
