I do not know what's going on in Sao Paulo but for some reason the reported COVID death rate starts to decrease unusually fast (infos from google covid satistics) in the last couple of days.
Sao Paulo:
Nov. 4th: 124 deaths (7day average: 61)
Nov. 5th: 115 deaths (7day average: 60)
Nov. 6th: 179 deaths (7day average: 77)
Nov. 7th: 11 deaths (7day average: 75)
Nov. 8th: 0 deaths (7day average: 73)
Nov. 9th: 2 deaths (7day average: 64)
Nov. 10th: 9 deaths (7day average: 63)

Brazil (all states):
Nov. 4th: 436 deaths (7day average: 229)
Nov. 5th: 389 deaths (7day average: 228)
Nov. 6th: 328 deaths (7day average: 242)
Nov. 7th: 59 deaths (7day average: 232)
Nov. 8th: 126 deaths (7day average: 236)
Nov. 9th: 183 deaths (7day average: 241)
Nov. 10th: 280 deaths (7day average: 257)

It is too early to interpret anything, but it will be interesting if this is just the usual reporting issue (e.g. usual weekend delay) or if the trend keeps this direction in the coming days.
Would love to see the number of enrolled CD16 patients in Sao Paulo enrollment
