Ninety-three (4.8%) of the 1,926 nasopharyngeal aspirates obtained from patients of all age-groups were positive for HBoV. Our detection rate is similar to that stated in other reports [2, 3, 8] . Generally, HBoV is detected in fewer than 8% of respiratory specimens [1, [8] [9] [10] [11] [12] [13] ; however, higher detection rates ranging from 10.3% to 19% have been reported [5, 14, 15] .
