This study screened Silk Road ethnic groups for viruses to understand Japanese origins. Results show these groups are not the Jomon Japanese origin, but Hepatitis B virus is common among them.

Area of Science:

  • * Anthropology
  • * Virology
  • * Epidemiology

Background:

  • * The Jomon and Yayoi periods represent key phases in Japanese prehistory.
  • * Understanding the origins of the Japanese population is a significant anthropological question.
  • * Viral markers can sometimes provide insights into population movements and origins.

Purpose of the Study:

  • * To investigate the potential origins of the indigenous Japanese (Jomon) population.
  • * To screen specific ethnic groups along the Silk Road for Human T-lymphotropic virus types I and II (HTLV-1 and -II), Human Immunodeficiency Virus (HIV), Hepatitis B virus (HBV), and Hepatitis C virus (HCV).

Main Methods:

  • * Antibody screening for HTLV-I, HTLV-II, HIV, and HCV in Han, Uygur, and Kazak populations.
  • * HBs antigen testing for Hepatitis B virus prevalence.

  • * Comparative analysis of viral marker distribution to infer population origins.

    • Main Results:

    • * All tested groups (Han, Uygur, Kazak) were uniformly negative for HTLV-I, HTLV-II, HIV, and HCV antibodies.
    • * A significantly higher incidence of Hepatitis B virus (HBs antigen) was detected across all studied groups.
    • * Northern Han: 11.9%, Uygur: 6.0%, Kazak: 9.1% prevalence of HBs antigen.

    Conclusions:

    • * The screened Silk Road ethnic groups (Han, Uygur, Kazak) are unlikely to be the origin of the indigenous Japanese (Jomon).
    • * Hepatitis B virus (HBV) is notably prevalent among the diverse ethnic groups residing along the Silk Road.
    • * Further research is needed to fully elucidate the complex origins of the Japanese population.
