These samples were tested for 18 pathogens using quantitative chain reaction (qPCR). The VP1 gene were amplified and sequenced from HBoV-positive samples. The viral genetic characterization was analyzed by comparing the HBoV1 sequences with reference sequences.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Of the 1,153 samples, the detection rate of HBoV positive was 6.85%, primarily detected in May 2023. The majority of HBoV positive cases were found in children under 5 years old. Clinical manifestations in HBoV-positive patients predominantly were fever and cough, with a clinical diagnosis of lower respiratory tract infection. Other viruses were also detected in 20% of HBoV-positive samples. All HBoV sequences identified in this study belonged to HBoV1, with the Ib sublineage being the predominant strain circulating in Yucheng during March\u2013June 2023.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>After the implementation of the optimized COVID-19 prevention and control strategy in December 2022, HBoV infection was prevalent in Yucheng, Henan in May-June 2023, mainly among children younger than 5 years old, especially those under 2 years old. The Ib sublineage of HBoV was the dominant circulating strain in Yucheng, Henan during March\u2013June
