However, the details from Esper et al.'s study-the seasonal distribution, the percentage of positive samples, the associated respiratory syndromes, and the numbers of infected children at various ages, for example-were heavily influenced by both the particular population that was investigated and the clinical setting, so it is essentially impossible to draw conclusions on the epidemiology, pathogenicity, and relative importance of HCoV-NH in relation to other respiratory viruses.
