Household responses to malaria and their costs: a study from rural Sri Lanka.

ABSTRACT

A study of the cost of malaria at the household level, community perceptions, preventive measures and illness behaviour linked to the disease was undertaken in 5 villages in the dry zone of Sri Lanka. The surveyed community had a high knowledge of malaria, although side effects of antimalarial drugs were often confused with symptoms of the disease. The community sought prompt diagnosis and treatment at 'western-type' facilities, with 84% making use of government facilities as their first choice and 16% preferring private facilities. The preventive measures used were burning coils (54% of families) and special leaves (69% of families), and 93% of the families had their houses sprayed with insecticides. Average direct expenditure on a single malaria episode was $3 US, with some families spending more than 10% of the annual household net income per episode. The highest expenditure was on special diets for the sick person, to neutralize the perceived heating effect of the disease and its treatment.

ABSTRACT

PIP Knowledge of community perceptions of malaria, treatment-seeking behaviors, and the household costs of illness is essential to the planning of sustainable malaria control interventions. These factors were investigated in household surveys conducted in 5 villages in Sri Lanka's dry zone in February 1995. 95% of the 216 families interviewed regarded malaria as their main health problem, followed by diarrhea and eye diseases. Malaria was ranked as the third most important community concern, following lack of water for cultivation and poverty. Overall knowledge of malaria's causes, symptoms, and treatment was high, although the side effects of antimalarial drugs were often confused with symptoms of the disease. Reported for the 3-month period preceding the survey were 178 episodes of malaria involving 160 families. Home treatment with paracetamol was the first step taken in 85% of cases; however, all families sought prompt treatment from Western-type facilities, especially government hospitals (48%) and mobile clinics (30%). No families consulted indigenous or ayurvedic physicians, despite their availability in the area. This utilization of prompt, effective treatment is presumed to reflect high knowledge about malaria, the perceived seriousness of the disease, and good transport facilities in the area. The total direct expenditure on a single episode of malaria averaged US $3; the median net annual income was $258. Special foods for malaria patients aimed at neutralizing the perceived heating effect of malaria and antimalarial drugs (e.g., sodas, oranges) were the most costly item. Adults lost an average of 7.8 days of work per episode and those accompanying them to health facilities lost 2.9 days. Preventive measures used by families included bed nets (23%), mosquito coils (54%), and insecticides (93%).
