"Allander and colleagues at the Karolinska Institutet in Stockholm, Sweden, first cloned the coding sequence of this new member of the family of Parvoviridae in 2005 from pooled nasopharyngeal aspirates (NPA, collection of aspirated fluid from the back of the nasal cavity).^[3] They used a novel technique called molecular virus screening, based on random cloning and bioinformatical analysis. This technique has led to the discovery of new viruses such as polyomavirus KI (Karolinska Institute)^[4] and WU (Washington University),^[5] which are closely related to each other and have been isolated from respiratory secretions.

"Several groups of scientists have since then found that HBoV is the fourth most common virus in respiratory samples,^[6][7] behind rhinoviruses, respiratory syncytial virus and adenoviruses.^[8]

"The name bocavirus is derived from bovine and canine, referring to the two known hosts for the founder members of this genus; bovine parvovirus which infects cattle, and minute virus of canines which infects dogs.^[9] " (Wikipedia article on Human bocavirus, accessed 5-2020).
