Just two weeks ago, the contagion rate of Covid-19 in Brazil reached its lowest point since April, when the spread first got out of control. The so-called Rt rate, measured by the Imperial College London was at just 0.68 — meaning that every 100 people would be expected to infect another 68, who would then infect 46 and so on, thus decreasing the spread.
By November 24, however, this rate reached its highest point since May, sitting at 1.31. This means every 100 people would be expected to infect 131 others, intensifying the spread of the virus.
These findings come as a group of researchers from five different institutions signed an open letter trying to warn citizens and politicians about the dangers of a second wave in Brazil.
The country’s case and death curves have risen after months of decline. Brazil’s most recent 7-day rolling average of new daily deaths sits at 496 — up from 324 on November 11.
