The Federal Government says the most critical zones are the nation's most populated: BA Metropolitan area, as well as the cities of Córdoba, Santa Fe and Mendoza.

However, in several other provinces such as Río Negro, Neuquén, Catamarca, Jujuy and Chaco, local governments have resumed intensive traffic control measures due to an accelerated spike in daily infections.
