MALARIA AND ITS TREATMENT IN RURAL VILLAGES OF ABOH-MBAISE, IMO STATE, NIGERIA

We examined the malaria situation among 489 children under 5 years of age in the rural villages of Aboh Mbaise, Nigeria, using a combination of a standard questionnaire technique and laboratory diagnosis to confirm clinical observations. The results show a high prevalence rate of 52.8% for Plasmodium falciparum in this area. The geometric mean parasite density (GMPD) was 19 361.4/mm3. The proportion of children with fever and/or parasitaemia was not related to age, although the numbers in the febrile group appeared to increase with age. Using 37.5°C as the threshold for fever, 48.7% of the heavily infected group (more than 1000/mm3) were afebrile while 51.3% were febrile. High grade temperatures above 38°C were associated with high parasitaemia above 10 000 parasites/mm3. Of the 911 children who died in the area within the last five years, 22.4% died of fever of unknown origin, 39.7% from malaria, 22.5% from convulsion, 10.5% from diarrhoea and 4.6% from cough. Chloroquine is the drug of choice for the treatment of malaria and there were many cases of drug abuse, and use of sub-curative doses prescribed by non-medically qualified staff. © 1990.
