A total of 232 families living in 210 households were surveyed. The actual number of children included in the study per category (rural/urban) was 177 and 383 respectively. The overall attack rate for the entire city for the time period April 1987 - April 1988 was 7 per 100,000 and the case fatality rate was 2%. The overall attack rate of Cebu City was 7 per 100,000 population whereas the overall attack rates of its urban and rural barangays were 5 and 20 per 100,000 respectively.
Forty-one children had measles between April 1987 and April 1988. The mean age for cases in urban barangays was 3 years while for the rural barangays was 2 years. Thirty-eight (93%) cases had no history of measles immunization; 2 were vaccinated before the measles episode and 1 was vaccinated a month after contracting the illness.
The two most common reasons for non-immunization were: 1) refusal to immunize the child at the health center because he/she belonged to the wrong age for measles immunization (26%); 2) frequent illness in the child (24%) Other children in the households either had histories of measles outside of the recall period or had no measles yet. No further inquiries were asked for this group of children
