Mortality due to Respiratory Syncytial Virus. Burden and Risk Factors.

Rationale: Respiratory syncytial virus (RSV) is the most frequent cause of hospitalization and an important cause of death in infants in the developing world. The relative contribution of social, biologic, and clinical risk factors to RSV mortality in low-income regions is unclear.

Objectives: To determine the burden and risk factors for mortality due to RSV in a low-income population of 84,840 infants.

Macronutrients during pregnancy and life-threatening respiratory syncytial virus infections in children.

Rationale: Respiratory syncytial virus (RSV) is an important cause of hospitalization and death in infants worldwide. Most RSV deaths occur in developing countries, where burden and risk factors for life-threatening illness are unclear.

Objectives: We defined the burden of life-threatening (O(2) saturation [O(2) sat] ≤ 87%) and fatal RSV infection, and characterized risk factors for life-threatening disease in hospitalized children.
