Seroepidemiology of human T-cell lymphotropic virus type I infection in Taiwan.
The epidemiological characteristics of human T-cell lymphotropic virus type I infection in Taiwan have been explored by an island-wide community-based survey, which was carried out among residents in 19 townships and metropolitan precincts randomly selected through stratified sampling. Serum specimens of 7278 healthy subjects were screened by enzyme-linked immunosorbent assay and confirmed by Western blot method. A total of 103 subjects showed positive or weak reactions by enzyme-linked immunosorbent assay, but only 35 of them were confirmed to be positive by Western blot analysis. The anti-human T-cell lymphotropic virus type I antibody positive rate was 4.81/1000. The seropositive rate increased with age in both males and females, and females had a greater seropositive rate than males for all the age groups. Aborigines and Hakka Taiwanese had higher seropositive rates than Fukien Taiwanese and Mainland Chinese. Those people with lower educational levels were found to be associated with higher anti-human T-cell lymphotropic virus type I seropositive rates.
