Note: For all calculations, numbers and percentages are based on weighted averages which are also adjusted for missing data. For these reasons, manual re-calculation might show slight differences (i.e., the total sample size will vary for each category as the missings within this category will differ). ^aCases are children with symptoms of pneumonia in the past two weeks, as reported by their caregiver
