Genetic characteristics of human coronavirus HKU1 in mainland China during 2018.

ABSTRACT: Human coronavirus HKU1 (HCoV-HKU1) is a pathogen that causes acute respiratory tract infections in children and circulates worldwide. To investigate the molecular characteristics and genetic diversity of HCoV-HKU1 in China, a molecular epidemiological analysis based on complete genome sequences was performed. A total of 68 endemic-HCoV-positive samples were identified from 1358 enrolled patients during 2018, including four HCoV-229E, nine HCoV-OC43, 24 HCoV-NL63, and 31 HCoV-HKU1. The detection rate of endemic HCoVs was 5.01% during 2018, while for HCoV-HKU1, it was 2.28%. Eight complete genomic sequences of HCoV-HKU1 were obtained and compared to 41 reference genome sequences corresponding to genotypes A, B, and C, obtained from the GenBank databank. Of the eight HKU1 sequences, four belo
