In late July 2026, Uruguay and Peru began targeted efforts to curb sexually transmitted infections among young people. Uruguay’s education agency launched a pilot project, “Hablemos de sífilis,” offering contests, community testing events and self‑care tools for adolescents in the Maldonado department, with plans to expand nationally. In Peru’s Puno region, a university‑based screening tested hundreds of students for HIV, syphilis and hepatitis B, identifying and referring positive cases for treatment.

A week later, the focus shifted to vector‑borne disease control. Peru’s health ministry received its first shipment of the Qdenga dengue vaccine, earmarked for children and adolescents in high‑risk Amazonian regions, while Argentina’s Chaco province opened a mass vaccination drive for residents aged 15‑59, urging early immunisation before the summer mosquito season. Both initiatives complement traditional vector‑control measures such as eliminating standing water.

Together, these actions illustrate a broader regional push to protect youth from diverse health threats through screening, education, and vaccination, with multiple South American countries coordinating disease‑specific campaigns within a unified public‑health framework.
