Sexual and vertical transmission dominate HTLV-1 infections in adults aged 25–69 years, accounting for 85% and 8% of infections across endemic foci.
- Why it matters: Transmission route contributions vary by setting, but the relative roles of vertical, sexual, bloodborne, and zoonotic pathways are not well quantified for specific endemic populations.
- What they did: Using a multiroute serocatalytic model fit to seven age- and sex-stratified HTLV-1 seroprevalence surveys (nine subpopulations) from French Guiana, Gabon, Cameroon, Japan, and central Australia, the study estimated route-specific forces of infection and attributable fractions.
- The result: Vertical transmission probability was 17% (95% credible interval 15–20), sexual probabilities ranged 0·02%–0·68% per year (1·6× higher in females), and hospital-related transmission contributed ~2% in Japan, ~5% in Cameroonian Bantu communities, and <1% elsewhere.
