Although Mycoplasma pneumoniae is an atypical bacterium, it was grouped with viral pathogens in this study due to the shared PCR-based detection methodology. HRV (Human Rhinovirus), HBov (Human Bocavirus), MP(Mycoplasma Pneumonia), HPIV (Human Parainfluenza Virus), HCOV (Human Coronavirus), INFA (Influenza A), HMPV (Human Metapneumovirus)
