With migrant settlements, construction labour camps and brick kiln clusters emerging as priority zones, Mysuru district has identified 1,396 high-risk areas ahead of the four-day Pulse Polio immunisation campaign scheduled from June 28 to July 1, even as authorities have stepped up efforts to ensure no child below five years is left out.

District Health and Family Welfare Officer Kumaraswamy P.C., who chaired the district task force coordination committee meeting on the National Pulse Polio Programme here on Monday, said that special surveillance would be maintained in vulnerable pockets and 51 mobile teams deployed for outreach activities.

The campaign will target children aged 0-5 years across the district, including those who have previously received polio drops. A total of 1,641 vaccination booths will be opened on June 28, and parents have been urged to bring all eligible children for immunisation.

Health workers will subsequently undertake door-to-door visits from June 29 to July 1 to identify children who miss the booth-based drive and administer the vaccine.

The officials said 7,78,059 households and 2,19,521 children in the 0-5 age group have been mapped for the campaign. The district will deploy 6,772 vaccinators and 328 supervisors.

Reproductive and Child Health Officer Siraj Ahmed said India has remained free of polio cases since 2011 and was declared polio-free by the World Health Organisation in 2014. However, continued reporting of cases in neighbouring countries such as Pakistan and Afghanistan has necessitated sustained surveillance and preventive immunisation efforts.

Transit booths will also be opened at key tourist destinations, including Mysore palace, Mysuru zoo and Chamundi Hill, on June 28 to cover children travelling with families.

During the 2025 Pulse Polio campaign, the district vaccinated 2,33,484 children against a target of 2,22,084, recording 105.13 per cent coverage. The officials called for coordinated action involving the departments of Women and Child Development, Education, Transport, Police and voluntary organisations to ensure the campaign’s success.
