Abstract

Introduction.  Hepatitis C virus (HCV) infection is an infection that may lead to cirrhosis and hepatocellular carcinoma. Most patients with HCV infection are asymptomatic. The previous study conducted in age group of 30-64 years and in two provinces. Additionally, most surveillance studies conducted in a point period; not longitudinally. This study aimed to evaluate HCV infection rate in all age groups in the northeastern, Thailand in a longitudinal fashion.

Methods. This was a surveillance study conducted in 20 provinces of northeastern, Thailand. The study period was between July 2010 and November 2019. During the surveillance, demographic data of participants were collected. HCV screening test was performed in each participant by using a rapid point-of-care assay. Rates of HCV infection in each province and in overall were calculated.

Results. During the surveillance period, there were 31,855 subjects who participated the project. Of those, 1,285 subjects (4.037%) were tested positive for HCV infection (Table 1). The HBV infection rate was highest in 2011 (8.98%): ranges 1.28 to 9.59%. The age group of over 50 years had 690 subjects with HCV infection (5.45%) out of 12,660 subjected tested in this age group. There was significant different among age groups (p < 0.001) and difference of age over 30 years and sex (p 0.043).

Conclusions: This longitudinal surveillance showed that HCV infection rates in northeastern, Thailand were varied across the provinces with the highest rate of 9.59%. The HCV infection should be aware in male with age over 30 years.
