Table 1.
HCV epidemiological data and previously published research.
Epidemiological and virological data from both Phetchabun and Khon Kaen were combined. The HCV seroprevalence age distribution was analyzed for both sets of data including the national survey of HCV seroprevalence in 2014 which served as a HCV burden representative in the country [4].

Phetchabun demographic and HCV seroprevalence of the samples (age between 18–30 years) recruited in 2017.

HCV seroprevalence in different age groups.
HCV seroprevalence in individuals aged 18–64 years in Phetchabun (red color), Khon Kaen (green color) and Thailand (purple color). Data were categorized into 5-year or 2-year interval. The line and bar graphs show HCV seropositivity and individual sample numbers in each age group, respectively. Khon Kaen and the national survey data were derived from previous studies [4,5].

Univariate and multivariate analyses of potential risk factors associated with HCV seroprevalence in Phetchabun.
Fig 2.
HCV seroprevalence in different birth cohorts.
The bar charts show HCV seroprevalence in birth cohorts born in 1951–1999 in (A) Phetchabun, (B) Khon Kaen Province and (C) the national survey. The area behind the bar chart represents the sample number in each birth year.

Fertility and birth rates of Thai population born in 1951–1999 and HCV related historical timeline transmission in Thailand.
(A) The bar and line graph respectively show the birth rate per 1000 population and birth fertility rate per woman during 1951–1999 in Thailand. These data are derived from the World Bank database [10,11]. (B) The bar charts show historical timeline and socioeconomic events that may be related to HCV prevalence and transmission in Thailand.
