Epidemiological study of measles in slum areas of Kolkata.

OBJECTIVE: An epidemiological study on measles was conducted among the under five children in slum areas of Kolkata to assess the incidence of measles. METHODS: 20 cluster sampling technique was followed and in each cluster 250 under five children were covered. Paramedical workers identified children of the target of age group who had history of measles in past one year and the medical officer confirmed the diagnosis following standard case definition. RESULTS: Incidence of measles was found as 5.76%. Incidence was equal in both the sex groups, but found more among infants. The incidence of measles gradually declined with the increase of age strengthening the view in favor of early immunization. Amongst the measles cases only 19.7% were immunized with measles vaccine. 100% of measles cases gave history of rash, 98.9% had history of fever, 82.8% reported that the rash started from face and progressed downwards to abdomen and leg. Cough, redness of eye and discoloration of skin were reported by 97.5%, 83.8% and 65.2% measles cases respectively. Only 16.9% and 8.6% children received Vitamin A oil before and after the illness respectively. 49% gave history of exposure to measles cases and 46.6% cases had measles within 2 weeks incubation period. CONCLUSION: The study highlighted the necessity of timely measles vaccine coverage, additional dose at a higher age and Vitamin A supplementation through IEC activities.

Intensified pulse polio immunisation coverage in slums of a metropolitan city: an appraisal.

A study was conducted by house-to-house visit during 2nd and 3rd round of IPPI in Nov and Dec 2000 in two slums adjacent to Medical College Kolkata. Total houses visited in these two rounds were 2836 and 611 children were immunised at home. Mothers of 503 children (who did not receive IPPI dose at booth on NIDs) were interviewed. For rest 104 children, mothers were not available during the time of visit. The result showed that infants were the largest group (30.6%) to receive vaccine at home. Majority (84.1%) was permanent residents of the locality. Only 4.2% were Bengali-speaking Hindus while most other were Hindi or Urdu speaking Muslims. "Health workers will bring vaccine at door steps" was the reason of non-attendance at booth by 30.2% parents. No routine immunisation was received by 14.9% children. The source of information regarding IPPI was, 45.4% from medical students, 28.5% from health workers, 15.1% from TV, 5.6% from relatives and neighbours, 3.6% from miking and 1.8% from newspapers respectively.
