CHILD MORBIDITY PATTERNS IN 2 TROPICAL SEASONS AND ASSOCIATED MORTALITY-RATES

Cross-sectional morbidity recorded during two successive quarterly sur vey rounds and subsequent 27-months mortality were studied in a random sample of 4238 preschool children in a rural Zairian area. Analysis f ocuses on morbid patterns, i.e. any combination of the principal signs and symptoms encountered in tropical areas (oedema, marasmus, cough, fever, diarrhoea and tachypnoea). Almost half the children (45-48%) ha d signs of morbidity, a very high rate. The 3-6 month age group emerge d as particularly vulnerable with the highest prevalences of all morbi d patterns except for isolated fever. Isolated cough was more prevalen t in the dry season probably as an effect of nightly indoor woodburnin g. All other morbid patterns were significantly more prevalent in the rainy season. Diarrhoea with cough was found to constitute half of all cases of diarrhoea. The results show that with a few simple questions on major symptoms and a brief examination by paramedical health worke rs, children with an increased risk of death can be identified. The me thod can be applied at under-5 clinics. Prognosis is particularly bad in severe malnutrition, especially when associated with diarrhoea, in diarrhoea with cough, cough with fever/tachypnoea and for children who are found sick both in the rainy and the subsequent dry season.
