Hepatitis A virus (HAV) and hepatitis E virus (HEV) infection in developing
countries are associated with contaminated food or water. Although Thailand is
non-endemic for HEV, sporadic infections may occur from zoonotic transmission.
Individuals between 7 months to 69 years (mean age = 32.8) from predominantly
Islamic Narathiwat (n = 305) and swine farm-dense Lop Buri (n = 416) provinces
were screened for anti-HEV and anti-HAV antibodies by commercial enzyme-linked
immunosorbent assay and automated chemiluminescent microparticle immunoassay,
respectively. Seroprevalence and relative antibody titers were analyzed according
to age groups. HAV IgG antibody positive rates in Lop Buri and Narathiwat
residents were 39.9% and 58%, respectively (p < 0.001). Greater than 90% of
individuals >50 years old in both provinces possessed anti-HAV IgG. In contrast,
seroprevalence for anti-HEV IgG was much higher in Lop Buri (37.3%) than in
Narathiwat (8.9%) (p < 0.001). Highest anti-HEV IgG prevalence was found among
21-30 year-olds (50%) in Lop Buri and 41-50 year-olds (14.1%) in Narathiwat. In
summary, fewer individuals possessed anti-HEV IgG in Narathiwat where most
residents abstained from pork and fewer swine farms are present. Therefore, an
increased anti-HEV IgG seroprevalence was associated with the density of swine
farm and possibly pork consumption. Adults were more likely than children to have
antibodies to both HEV and HAV.
