a For this analysis, only children who had specimens tested for both bacteria and viruses were included. Variables that were tested in the model but did not reach significance: sex, clinical presentation of fever/feverish, fatigue, chills, abdominal pain, myalgia, dyspnea, examination findings on presentation: hypoxia, rhonchi, wheezing, chest indrawing, tachypnea, chest retraction; radiographic findings: single and multiple lobar infiltrate, pleural effusion; comorbid condition: chromosomal disorder; household size; interaction between age and codetection.
