Table 2– Clinical characteristics of rhinovirus prolonged, re-infection, mono-infections and co-pathogen infections

	Rhinovirus infection			Mono-infection	Co-pathogen	*p-value versus* prolonged infection**		*p-value versus* re-infection**
	Prolonged	Re-infection	p-value			Mono-infection	Co-pathogen	Mono-infection	Co-pathogen
Patients n	6	11		210	123
Duration of illness days	25 (21–35)	18 (13–30)	0.62	21 (15–31)	21 (14–30)	0.43	0.50	0.43	0.58
Maximal symptom score^#	2 (2–3)	3 (2–5)	1.00	2 (1–3)	2 (2–3)	0.58	0.74	0.06	0.15
Duration of symptom score ≥2 days	4 (2–7)	6 (2–10)	0.63	4 (2–7)	4 (2–6)	0.87	0.97	0.59	0.60

Data are presented as median (interquartile range), unless otherwise stated. Clinical characteristics for rhinovirus mono-infections and co-pathogens were estimated for subjects with a follow-up sample negative for all tested pathogens. Mann–Whitney U-test was used to obtain p-values. ^#: patient diary symptom score scale: 0: normal/not affected, 1: very little problem, 2: slight problem, 3: moderately bad, 4: bad, 5: very bad, 6: as bad as it could be.
