Early child health in Lahore, Pakistan: VI. Morbidity.

Morbidity patterns were studied according to the age, area of living, sex and season among 1476 monthly followed infants born during 1984-1987 in four socio-economically different areas in Lahore, Pakistan. Infections were responsible for 87.0% of the morbidity during the first two years of life. The overall monthly based morbidity was 77.0% between birth and 24 months of age; diarrhoeal diseases 30.3%, upper and lower acute respiratory tract infections (ARI) 22.4%, skin and eye infections 6.7% and skin rash 6.2%. The vaccine-preventable diseases were only 0.5% of the total. Anaemia and rickets were rare (2.0%), but commonly seen among the nutritional deficiencies. Diarrhoea, tetanus, septicaemia, ARI and infections of the skin and eyes were reported more during earlier ages and from the three poorer areas of living. Diarrhoeal diseases, respiratory tract, skin and eye infections, in particular, followed clear seasonal patterns, while scabies prevailed throughout the year. The presence of these many preventable infections and illnesses implies that proper planning of interventions must be forthcoming.
