Taxonomy and global prevalence of four viral groups (seasonal coronaviruses, rhinoviruses, adenoviruses and bocaviruses) in individuals with respiratory tract infections (RTIs).

Virus	Family	Genome	Subtypes	Global prevalence in RTIs %
Seasonal coronavirus (sCoV)	Coronaviridae	ss(+)RNA	229E-CoV, NL63-CoV, OC43-CoV, HKU1-CoV	0.5–18.4
Rhinovirus	Picornaviridae	ss(+)RNA	3 species (A–C), >100 serotypes	13–59
Human adenovirus (HAdV)	Adenoviridae	dsDNA	7 species (A–G), >80 genotypes	1–36
Human bocavirus (HBoV)	Parvoviridae	linear ssDNA	HBoV 1–4	1–56.8

ss, single stranded; ds, double stranded; (+), positive sense; CoV, coronavirus; sCoV, seasonal coronavirus; HAdV, human adenovirus; HBoV, human bocavirus.
