Pneumonia in Children

چکیده
Etiological factors vary with age, source of infection (community vs. hospital acquired pneu‐ monia) and underlying host defects (e.g immunodeficiency). Viruses are the most common etiological factors in preschool children, although in many cases more than one causative agents can be identified. There are several emerging pathogens in community acquired pneumonia in children: virulent strains of Streptococcus pneumoniae that are not present in currently available vaccines, Panton-Velentine leucocidin producing Staphylococcus aureus, human Bocaviruses and metapneumoviruses being the most important.
