Abstract

To assess the impact on health of the cyclone and tidal wave that struck the southern coast of Bangladesh on the evening of 29 April 1991, a team of health professionals visited cyclone affected areas from 4-27 June, 1991. Team members met with health workers and officials of the Government of Bangladesh and with staff from non-governmental organizations, and conducted field surveys in two severely affected areas. Mortality among the 135 households surveyed (pre-cyclone population 1, 123) was 14 per cent. At highest risk of deaths were children of less than 10 years (26 per cent mortality) and women of more than 40 (31 per cent mortality). Almost all deaths occurred as a result of drowning from the tidal wave that accompanied the cyclone. Although 95 per cent of the population surveyed had received warning of the cyclone four or more hours before it struck, the 300 existing cyclone shelters had capacity for only 450,000 of the 5,000,000 people affected by the cyclone. Deaths following the cyclone were few. Diarrhea caused by Vibrio cholerae and Shigella dysenteria type 1, both of which are endemic in Bangladesh, occurred in the post-cyclone period. Reports by the national Diarrhea Surveillance System of large increases in diarrheal incidence following the cyclone were difficult to assess because of inconsistencies in pre- and post-cyclone reporting methods. No increase in other infectious diseases was identified. Although water availability had been a major concern following the cyclone, the tubewell system was functioning well in the area that was surveyed. Distribution of relief assistance by the Government of Bangladesh and by non-governmental organizations was good, with 95 per cent of families surveyed receiving food aid within five days of the cyclone. The major health effect of this cyclone was acute deaths due to drowning. Preventing deaths during future cyclones will require increasing accessible shelter.
