Measles, immunisation and disease: rapid epidemiological assessment in two trans-Yamuna villages of Delhi.

A community investigation was conducted in 2 villages of east Delhi, having 15,000 population. Ten per cent households were selected from both the villages by systematic random sampling and all the under 3-year children in selected households were included in the study. A total of 126 under 3-year children from 360 households were investigated. Total children immunised against measles were 86. Most of the 86 immunised children were vaccinated between 9 and 11 completed months. Of the 80 children aged 12 months or above, 12(15%) were unimmunised. Main reason behind non-immunisation was parental apathy. Of the total 126 surviving under 3-year children, 12(9.52%) had a history of probable measles. Two of these children had already measles before they could be eligible for measles vaccination as per the current schedule.
