Overview

  • More than 500 carbon monoxide poisoning cases and around 200 related deaths have been recorded nationwide this winter.
  • Salta’s Hospital Público Materno Infantil treated 32 children for poisoning between May 31 and July 3, nearly tripling last year’s total for the entire season.
  • A recent gas leak in Cosquín killed a 65-year-old woman and her 10-year-old granddaughter, marking the seventh winter fatality in just one week.
  • Health authorities and specialists are urging homeowners to install certified CO detectors, keep vents clear, and schedule annual inspections of gas appliances by certified technicians.
  • Experts warn that a 30% rise in bottled gas prices and limited safe heating alternatives are pushing low-income households toward deadly improvised methods.
