Comparison between frequencies of sole bacterial and sole viral infection among 91 children hospitalized with community-acquired pneumonia and detected aetiology, after excluding cases with co-infection

Aetiology	Severity by the World Health Organization 2000 criteria
	Non-severe (n = 24)	Severe (n = 58)	Very severe (n = 9)
Sole bacterial infection	3 (12.5)	17 (29.3)	5 (55.6)
Sole viral infection	21 (87.5)	41 (70.7)	4 (44.4)

Results in n (%)

p = 0.04 for the frequency of sole bacterial infection across three distinct severity categories among patients with sole aetiological agent infection
