Soon, viral spread in the metropolitan area and CABA became sustained, with serious and fatal cases. Between April and July in the Province of Buenos Aires and CABA (Figure A13-5), the majority of cases at the beginning of the outbreak belonged to the group of schoolchildren 5-15 years old. The recommendation to close schools from June 8th to 19th may have helped to reduce transmission to other age groups, since it would have limited the transmission among the primary spreaders. This measure could also have avoided the high spread to other parts of Argentina. As shown in Figure A13-6, the outbreak in the interior showed the same start for all age groups, with the majority of cases in the 15-44 years old age cohort (Figure A13-6).
The first fatality occurred on June 15th and, 10 days later, 17 more fatalities were reported in the Province of Buenos Aires and 5 in CABA.
The lack of epidemic containment in CABA and the metropolitan area of theProvince of Buenos Aires led to the spread in major cities within the Province of Buenos Aires as well as several provincial capitals, starting with Santa Fe.
