Genotype 2 had a frequency of 2.66%, with the most widely distributed subtype being 2a at 2.11% of the patients. Its other subtypes, 2b and 2c, had frequencies of 0.17% and 0.36% respectively. The most prevalent genotype among all isolates was 3 (65.35%), with the most frequent subtype being 3a (55.15%), followed by 3b (7.18%).

The prevalence of untypeable and mixed genotypes was 21.34% and 3.53% respectively. Estimating genotypes proves to be a productive method in assisting with the duration and selection of antiviral treatment. Different HCV genotypes can exhibit variations in their response to specific antiviral treatments. Different genotypes may have distinct natural histories, including variations in disease progression and severity.

A meta-analysis was conducted to evaluate the awareness of HPV and HPV vaccines, as well as the acceptance of HPV vaccines, providing evidence-based strategies to promote HPV vaccination. Based on the databases of CNKI, Wanfang, VIP, PubMed, Embase, and Cochrane library, the literatures about the awareness of HPV and HPV vaccines, as well as the acceptance of HPV vaccines among parents of primary and junior high school students were collected from the inception to June 2023. Subgroup analysis was used to find the source of heterogeneity. Publication bias was evaluated using funnel plots and Egger's test. Fifteen literatures with 21,853 participants were included. The pooled HPV awareness, HPV vaccine awareness and acceptance rates among parents of primary and junior high school students in China were 42.90% (95% CI: 33.34%–52.47%), 28.11% (95% CI: 18.20%–43.41%), and 55.29% (95% CI: 45.85%–64.36%), respectively. The survey period and the proportion of female parents were the heterogeneity in awareness of HPV and HPV vaccines, as well as acceptance of HPV vaccines by subgroup analysis. Additionally, regional distribution emerged as another significant source of heterogeneity in HPV vaccine acceptance. The primary cause for parents' reluctance to vaccinate their children was theirs worries about the safety of the vaccines (66.21%). Though the awareness of HPV and its vaccines was low among parents of primary and junior high school students in China, the acceptance of HPV vaccines was relatively high.
