Human bocavirus 1 (HBoV1) can persist in nasopharynx and
tonsils. Using HBoV1 serology, reverse-transcription polymerase chain reaction (PCR) for detecting messenger RNA
(mRNA) and quantitative PCR for HBoV1 genome load count,
we studied to what extent the HBoV1 DNA loads in nasopharynx correlate with acute infection markers. Tonsillar tissue,
nasopharyngeal aspirate, and serum were obtained from 188
elective adeno-/tonsillectomy patients. Relatively high loads of
HBoV1 DNA were detected in the nasopharynx of 14 (7%) primarily asymptomatic subjects with negative mRNA and/or serodiagnostic results. Quantitative HBoV1 DNA PCR may have
lower specificity than HBoV1 mRNA detection for diagnosing
symptomatic infection.
