South Africa is reporting ~10,000 cases/day.Chile is reporting thousands of cases a day. The cross-society systematic uncertainties are the major challenge, as every country and culture is attacking this thing differently (and NZ is crushing it). If there is a strong seasonal effect, it should be apparent throughout global datasets, both from a latitude-dependent dynamic in the northern hemisphere and variation with opposite sign for locations with equal and opposite latitude. It is my continued guess that meaningful bounds on any seasonal effect are not inaccessable. From US data alone, it is clear that R_0 is not impacted by a factor of ~2-5 by summertime climate. We're still losing.
