[Acute respiratory infections in pediatric hospital at Bobo-Dioulasso (Burkina Faso)]. / Les infections respiratoires aiguës en milieu hospitalier pédiatrique de Bobo-Dioulasso (Burkina Faso).

BACKGROUND: Acute lower respiratory tract infections are the primary cause of morbidity in developing countries. POPULATION AND METHODS: Six hundred and sixty seven children (379 boys, 288 girls, aged 0-30 months) admitted for lower respiratory tract infections from January 1990 to March 1991 were included in the study. Immediate medical history was collected from the mother. The weight, height, temperature and clinical manifestations, plus the results of chest X-rays, parasitologic and bacteriological examination of stools, and blood smear for malaria were recorded for each patient. Sero-immunologic study for HIV infection of 473 of the patients aged 12-36 months and their mothers also took part in a sero-immunological study for HIV infection. RESULTS: Lower respiratory tract infections were the second major cause of admission (16.8%) after malaria (28.7%). Infections peaked between 6 and 11 months of age (29.5%). The main diseases were pneumonia and bronchial pneumonia (54%) followed by bronchiolitis (21.7%). Almost half the patients were admitted during the hot, dry season. Two hundred and eighty seven patients (43.4%) were referred only after they had been suffering from the disease for 3 to 9 days, partly explaining the high level of mortality. One hundred and twenty one patients (20.9%) died; the main cause of death was staphylococcal pneumonia (57.9%), followed by pneumonia and bronchial pneumonia (29.3%). Some criteria for severity could be identified, based on pulmonary signs and symptoms and associated manifestations (dehydration, malnutrition, convulsions, anemia). Twenty two patients were positive for HIV-1 infection. CONCLUSIONS: This study confirms that acute lower respiratory tract infections remain a public health problem. Early diagnosis and treatment are necessary to reduce mortality.

Mass measles vaccination in urban Burkina Faso, 1998.

OBJECTIVE: To assess the impact of the National Immunization Days (NIDs) on measles vaccine coverage in Burkina Faso in 1998. METHODS: During the week after the campaign, in which measles vaccine was offered to children aged 9-59 months in six cities regardless of vaccination history, a cluster survey was conducted in Ouagadougou and Bobo Dioulasso, the country's two largest cities. Interviewers visited the parents of 1267 children aged up to 59 months and examined vaccination cards. We analysed the data using cluster sample methodology for the 1041 children who were aged 9-59 months. FINDINGS: A total of 604 (57%) children had received routine measles vaccination prior to the campaign, and 823 (79%) were vaccinated during the NIDs. Among those who had previously had a routine vaccination, 484 (81%) were revaccinated during the NIDs. Among those not previously vaccinated, 339 (78%) received one dose during the NIDs. After the campaign, 943 (91%) children had received at least one dose of measles vaccine. Better socioeconomic status was associated with a higher chance of having been vaccinated routinely, but it was not associated with NID coverage. CONCLUSION: The mass campaign enabled a substantial increase in measles vaccine coverage to be made because it reached a high proportion of children who were difficult to reach through routine methods.
