Pneumonia among young infants in rural Southeast Asia (Bohol Island, Philippines).

Objective: To develop a clinical algorithm that can be used to identify pneumonia deaths in young infants in developing countries and estimate the disease burden in this population.

Patients And Methods: Infants younger than 60 days hospitalized with signs of severe pneumonia who underwent clinical, microbiologic and radiological evaluation were the subjects. Stepwise logistic regression and subtractive iterative process were used to derive the algorithm.
