The trend line is observed, and each point of dispersion corresponds to the daily record reported by each country. It can be seen how Argentina is climbing the curve of cases without reaching a peak. Chile had it between the dates of May 20 and June 30. Colombia from July 19 and currently, the cases seem to be decreasing and in Ecuador, which had its peak of cases in the month of April–May.
