Acute respiratory infections in children: a community-based study comparing a primary health center and a pediatric unit, Republic of Guinea.
OBJECTIVE
A community-based study was carried out in the Republic of Guinea in order to evaluate the frequency of occurrence, severity of illness, risk factors and the results of planned treatment of acute respiratory infections (ARI) in children under the age of 15 years.


METHODS
The study was performed over a 1-year period in 2 distinct areas, 1 rural and 1 urban. A total of 2622 ARI were identified among children under 15 years of age. In the rural area, data were collected by primary health-care workers and by 2 physicians who were trained to supervise the study.


RESULTS
Among the rural population, 1422 ARI were identified. In the city center, Conakry, 1200 ARI were identified in one children's hospital. The child population under 5 years of age was significantly greater in the rural area (95.2%) than in the city center (83.2%) (P < 0.0001). Malnutrition affected 10.6% of all the children. There were discrepancies in symptoms and signs affecting the 2 groups but the severity scores, including children under 5 years of age, were not significantly different: including children under 5 years of age, were not significantly different: 10-11% of the children were considered to have severe disease and 6.2% required urgent referral to hospital. Upper and lower respiratory infections (URI and LRI) were equally represented (49.9% and 50.1% respectively). Distribution of each type of ARI was significantly different in the 2 groups: there were significantly more URI in the city center, especially tonsillitis. Bronchitis and bronchopneumonia occurred significantly more often in the rural area. Pneumonia and bronchopneumonia represented 9.8% of all ARI. Use of antibiotic therapy was known in 2557 patients: 1268 URI and 1289 LRI. In children with URI, 69.7% did not receive antibiotic therapy, 29.9% received 1 antibiotic and 0.03% received 2 antibiotics successively. Children from the city center received significantly more antibiotics than in the rural health center. In children with LRI, 17.8% did not receive antibiotic therapy, 81.7% received 1 antibiotic and 0.05% received 2 antibiotics successively. There was no significant difference between the 2 centers in antibiotic prescription. Clinical outcome showed that 93% of children were considered to be cured at day 7 and 99.4% at day 14. 14 children with severe pneumonia died. The infection cost (antibiotics plus other drugs prescribed as supportive care) was 0.45 US$ per child in the rural area and 9.7 US$ in the children's hospital.


CONCLUSIONS
This supervised study constitutes the first large longitudinal study concerning respiratory infections in West Africa. It demonstrates that simple guidelines are valid in order to prevent mortality and complications. Care appropriate to population requirements in term of infectious diseases can be delivered with low cost and low technology.
