The study examined how demographic and socioeconomic factors impact infection rates in adolescents in Switzerland over a 3-year period.
Among 196 adolescents aged 15-16, a 9.7% infection rate was found, with a significant disparity where 30% of foreign nationals tested positive compared to 7.3% of native adolescents.
The low overall infection rate among Swiss adolescents suggests a high standard of living, which seems to lessen the impact of socioeconomic factors on infection prevalence.
