Abstract

  1. •

    Currently, HCV 6a has replaced 1b as the most prevalent subtype in blood donors in Guangdong.

  2. •

    HCV 6a was the predominant subtype in males and older donors, while 1b predominated in females and younger donors.

  3. •

    HCV 6a may expand from Guangdong to other districts of China, and is worthy of attention.

Distribution and time trends of different HCV subtypes among blood donors between 2004 and 2019 in Guangdong, China. A Circular form of the phylogenetic tree based on all 743 E1 sequences. Different subtypes are shown in different colors, as indicated on the tree. The pie chart inside the tree indicate the percentages occupied by different HCV subtypes. B Characteristics of HCV infected blood donors in Guangzhou from 2004 to 2019. C Temporal distribution of HCV genotypes in individuals of Guangdong and non-Guangdong origin over the four study periods (2004–2019). Each study period consisted of four years, and Chi-square trend test (linear-by-linear association) was used to calculate the P-value for 1b, 6a, and others (including 1a, 4a, 6e, and 6n), respectively. D Temporal distribution of HCV genotypes in male and female blood donors. E Temporal distribution of HCV genotypes in the younger age group (<40 years) and older age group (≥40 years).
