Argentina faces surge in tuberculosis cases and rising HIV infections

Argentina is confronting a sharp increase in tuberculosis, with 6,482 cases reported in the first 22 epidemiological weeks of 2026—a 71.6% rise since 2020 and the highest numbers recorded since the pandemic. Health officials point to social vulnerability, delayed diagnosis, treatment interruptions, overcrowding and growing poverty as key drivers. In parallel, the country is seeing a growing HIV epidemic: new diagnoses rose to 6,900 in 2023‑2024, and nearly half of people living with HIV are diagnosed late, often after severe immune decline. Public‑health groups warn that the lack of government campaigns and shortages of prevention supplies are worsening the situation.

Regional responses are underway. In Chile’s Maipú district, a free HIV testing event was held on 26 June, offering rapid tests and counseling to the community. Argentina’s Neuquén province launched a free, confidential HIV testing campaign from 26‑28 June, targeting high‑incidence areas and promoting early diagnosis and preventive measures such as PrEP and PEP. Similar outreach efforts are being organized across Argentine cities, including Mar del Plata, where NGOs provide free testing and education.

Health experts stress that early testing and sustained treatment are essential to curb both diseases, improve survival rates, and prevent further transmission.
