TL;DR: Estimating causes of pneumonia in young African and Asian children, using novel analytical methods applied to clinical and microbiological findings, estimated that viruses accounted for 61·4% (95% credible interval [CrI] 57·3–65·6) of causes, whereas bacteria accounted for 27·3% (23·3-31·6).

TL;DR: Upper airway pneumococcal colonization density among children hospitalized with World Health Organization–defined pneumonia was associated with microbiologically confirmed pneumococCal pneumonia (MCPP) and the optimal colonization density threshold was ≥7 log10 copies/mL.

TL;DR: Elevated CRP was positively associated with confirmed bacterial pneumonia and negatively associated with RSV pneumonia in PERCH, suggesting CRP may be useful for distinguishing bacterial from RSV-associated pneumonia, although its role in discriminating against other respiratory viral- associated pneumonia needs further study.
