Detection rate of different viruses or virus subtypes in children with CAP. CAP: community-acquired pneumonia; RSV: respiratory syncytial virus; HEV/HRV: human enterovirus/human rhinovirus; HPIVs: human parainfluenza viruses (including HPIV1–4); HBoV: human bocavirus; HMPV: human metapneumovirus; HAdV: human adenovirus; Flu A: influenza A virus (including 2009 pandemic H1N1 influenza A virus, H3 subtype influenza A virus); HCoVs: human coronavirus (including HCoV-229E, -OC43, -NL63 and -HKU1); Flu B: influenza B virus. The symbol “*” indicated that there was statistic difference in the detection rate between north and south China using the chi-square test or the Fisher’s exact test. A P < 0.05 was considered statistically significant.
