Considering the positivity rate of tests is still like 50%+ (when it “should” be 5%) there is a pretty strong likelihood that the real number of cases is significantly higher. Argentina is now ranked number 19 with the most confirmed cases in the world, sitting right between Germany and France who have both managed to slow infection down to a crawl.
As has been the case in most places in the world once 20%-ish of the population of a city are exposed to a virus the number of cases seems to drop off significantly and quickly. Apparently CABA may be nearing this number. Perhaps that effect won’t last forever but it buys enough time to return to normality. This is why Paris, Barcelona, New York, Düsseldorf, Milan etc are all going about their lives pretty normally for months now. Everyone I know in these cities are currently enjoying summer vacations at some idyllic Mediterranean beach or in their offices preparing for such a trip...
Even if this phenomenon works here given the fact that each province has taken a different strategy (some have tried to suppress the virus, others have tried to slow the spread) I think it’s not going to change much on a national level and re-enabling circulation since Argentina would end up looking like USA or Brazil where cities like New York and Rio go back to “normalish” while other parts of the country go wild with virus playing catch up for many months (year?) to come.
