National Deworming Day: How India Built a Day to Treat Millions
Published · By Gaurav Phogat
National Deworming Day is India’s twice-yearly drive, on 10 February and 10 August, to give albendazole tablets to children and adolescents through schools and anganwadi centres. The campaign created the day in 2015 and scaled from 140 million children to national coverage within a year. The lesson: when the action is simple and the delivery system already exists, a fixed date can move an entire country.
About National Deworming Day
National Deworming Day (NDD) is held on 10 February and 10 August each year, with mop-up days for children who miss the main day. The Ministry of Health and Family Welfare launched it in 2015; the first NDD was held on 10 February 2015. It covers children and adolescents aged 1 to 19, in school or not. The Ministries of Health, Education, and Women and Child Development run it together: teachers and anganwadi workers give albendazole tablets, with ASHA outreach for children outside school. The ask of families is simple: make sure every child takes the tablet on the day, or on the mop-up day.

The problem it had to solve
The WHO estimated that 241 million Indian children aged 1 to 14 were at risk of parasitic worm infection. Treatment is cheap and simple, but reaching every child in a country of India’s size is not. The communication problem was just as real: parents had to trust a tablet given at school to a healthy-looking child, and teachers had to see it as part of their job.
The idea in one line
One tablet, one day, every child: use the places children already gather.
How it worked
- Use existing infrastructure. Tablets go through schools and pre-schools, with the education department preparing schools and anganwadi workers covering younger children.
- A clear school protocol. Schools had to arrange clean drinking water, spoons to crush tablets, a cool ventilated room and the contact details of the nearest health centre.
- A safety net. Mop-up sessions reach children who were absent on the main day.
- Independent checking. An independent agency monitored whether protocols were followed and whether school-reported numbers were accurate.
- A large, trained workforce. For the February 2016 round, over 900,000 education and health workers gave tablets across 561 districts, about 8 crore children aged 1 to 5 and 19 crore aged 6 to 19 were targeted, and 137 districts already covered by a lymphatic filariasis drug programme were left out to avoid duplication.
- Rapid scale-up. From a first group of states in 2015, it went to all states and union territories in 2016, and to a twice-yearly schedule.
Results
Reach grew fast. About 140 million children were treated in 2015 and about 270 million targeted in 2016 in 536 districts, per the Centre for Public Impact. In 2017, 25.6 crore children were treated in the February round and 22.8 crore in the August round, and the February 2018 round aimed for more than 32.2 crore. These are coverage figures, much of it based on school reporting. They show delivery at scale, not health outcomes.
What makes it stand out
- The behaviour ask is tiny. One tablet, once every six months, is about as simple as a health action gets.
- The day is the distribution plan. The date is not decoration; it synchronises teachers, health workers and supplies across the country.
- Trusted messengers. Teachers and anganwadi workers carry more weight with parents than any advert.
- Built-in repetition. Two fixed dates a year turn a campaign into a routine families expect.
Criticism and limits
Two issues stand out. First, safety fears. In February 2016, 236 children in five states reported mild adverse effects such as nausea and giddiness and were observed in hospital before being discharged without serious complications. The health minister had to publicly reassure parents. Any mass campaign needs a rapid-response plan for this kind of news, because one worried headline can undo months of trust. Second, the evidence debate. A Cochrane review found “substantial evidence of no benefit in terms of haemoglobin, cognition, school performance, and mortality” from mass deworming programmes, while other researchers disagree; the argument became known as the “worm wars”. Coverage data also depend heavily on school self-reporting, which is why independent checks matter.
Would it pass in India today?
NDD is a government programme, so the NMC rules on medical practitioners’ advertising are not the frame. For a hospital supporting it, the work is health education on a national day, allowed under clause 8.2 of the NMC 2026 guidelines. Photos of identifiable children taking tablets should not be used to promote the hospital (clause 8.1(v)), and any data captured about children needs verifiable parental consent under the DPDP Act. Medical claims about benefits must match official guidance, in line with ASCI’s rules against misleading claims.
What an Indian hospital can borrow for National Deworming Day
- Low (under Rs 1 lakh): myth-busting for parents. Channel: WhatsApp forwards and Instagram reels in local languages, a week before 10 February and 10 August. A paediatrician explains, in their own name, what the tablet is, why the mop-up day exists and which mild effects to expect, using official guidance. Compliance: health education under clause 8.2 of the NMC 2026 guidelines; label any AI-generated explainer visuals (clause 7.2).
- Mid (Rs 1 to 10 lakh): school partnership kits. Channel: schools near the hospital, plus a simple landing page. Provide teachers with printed reminders and a contact number for the nearest health centre, echoing the official school protocol. Compliance: no hospital promotion to children; keep the kit educational and unbranded beyond a small credit; no superlative claims (clause 8.1(iii)).
- High (above Rs 10 lakh): a rumour-response desk. Channel: a press and social media monitoring setup with district health officials during each round. If adverse-event rumours spread, paediatricians give calm, factual updates to local media. Compliance: factual public communication fits clauses 8.2 and 8.3; never share identifiable child details, and follow DPDP rules on children’s data.
