^† Measured by a particle agglutination method.

^‡ Diagnosed as sATL because of increased abnormal lymphocyte number, although the infected cells were polyclonal.

^§ Diagnosed as sATL because of the presence of skin lesions.

HTLV‐1, human T‐cell leukemia virus type‐1; ACs, asymptomatic HTLV‐1 carriers; ATL, adult T‐cell leukemia; sATL, smoldering‐type ATL; PMBC, peripheral blood mononuclear cell; WBC, white blood cell.
