Argentina: good to know

  • PEP in this country. Argentina's Ministry of Health says PEP and PrEP are available free of charge to everyone who needs them under Law 27.675, and that PEP must be started as soon as possible and no later than 72 hours after the exposure. The page does not say how this applies to short-term visitors.
  • PEP in this country. Fundación Huésped says PEP is free and available at public health centres and hospitals, and that it is taken for 28 days. In practice this means going to a public hospital's emergency department (guardia) as soon as you can.
  • What visitors pay. Public hospitals are no longer free for every foreigner. The national government says hospitals run by the national state now charge foreigners who are not permanent residents: you must show valid health insurance or pay before non-emergency care. Emergency care cannot be refused or delayed, and the treating professional decides what counts as an emergency.
  • What visitors pay. In the City of Buenos Aires, a March 2025 Ministry of Health resolution gives foreigners with permanent or temporary residence the same access to city hospitals as nationals, sets a billing procedure for foreigners without an Argentine ID, and states that urgent or emergency care may never be refused or restricted. The community organisations listed here test everyone free of charge.
