Abstract
Human bocaparvoviruses (HBoVs) belong to the Parvoviridae family, being currently classified into four species (HBoV1–4). These viruses have been found in association with respiratory and gastroenteric symptoms, as well as in asymptomatic individuals. This study aimed to investigate the occurrence of HBoVs in infants under 5 months old admitted to a Neonatal Intensive Care Unit (NICU) during the COVID-19 pandemic (between March 2021 and March 2022). Clinical samples (nasopharyngeal swab, serum, stool, and urine) were screened by qPCR TaqMan. The HBoV was detected in samples of 31.6% (12/38) of participants. The most frequent alteration among the HBoV-positive neonates was the chest X-ray with interstitial infiltrate, followed by tachycardia and vomiting. Viral DNA was detected in more than one type of clinical sample in three of the participants in association with respiratory symptoms. Two participants had positive stool samples with or without enteric symptoms. HBoV intermittent and continuous positivity patterns were observed. The present study stands out for the prospective evaluation of positivity for HBoV in different types of clinical samples from a population of hospitalized infants. Our data supports circulation of HBoV in nosocomial environment during the COVID-19 pandemic.
