Tuberculosis cases rise 71.6% since 2020 in Argentina, mortality a concern

Tuberculosis continues its alarming spread across Argentina, with cases rising significantly and a persistent mortality rate that claims one life approximately every seven hours. Official data reveals a stark increase in infections, keeping health authorities on high alert.

This ancient, yet preventable and treatable disease, primarily affects the lungs and transmits through the air. While the BCG vaccine, administered at birth, offers protection against the most severe forms, especially in children, it does not guarantee complete prevention of pulmonary tuberculosis. Treatment involves several months of antibiotics.

Experts highlight that the rise in cases cannot be solely attributed to health system issues. Factors like malnutrition, overcrowding, and other social determinants play a crucial role in the disease's transmission. "Tuberculosis is a disease that has a lot to do with the social aspect," noted an infectious disease specialist.

Official figures show a steady upward trend in notifications between 2020 and 2026. Cases climbed from 3,777 in 2020 to 6,482 by May 2026, marking a 71.6% increase. Although 2021 saw a slight decrease, cases have risen consistently since 2022, reaching the highest point in the recorded series in 2026. Men account for a higher proportion of diagnoses (60.7% in 2025), with the most affected age group being 15 to 44 years old.

Geographically, the most significant increases in contagion have been observed in the Center, NEA, and Cuyo regions. Provinces like Misiones, Mendoza, Entre Ríos, Santiago del Estero, and Santa Fe have seen substantial percentage increases. In absolute numbers, Buenos Aires province recorded the largest rise, followed by Santa Fe and Córdoba. Conversely, cases decreased in Buenos Aires City, Jujuy, La Rioja, and all jurisdictions in the southern region.
