A quick look at the statistics indicates Brazils deaths per 100K population is actually below the USA’s. Their case fatality is just slightly higher, probably given slightly lower standards of medical care. They are definitely in a 2nd wave, merely behind the 2nd wave that occurred in USA and other places
Its a tough political decision, but they should do nothing, except trying to implement best practices in treating Covid cases and protecting the elderly. The trend will peak and decline soon.
Case Fatality Rate and mortality rates are a snapshot in time. they reflect the here and now and the past but not what may come. For example, after 2 months of having their ICUs overwhelmed, their CFR and mortality rate will certainly surpass the United States. Doing nothing will not benefit them or us. Once that disaster starts jumping borders, it’s going to screw with us “six ways from Sunday”.
That is something no one here is taking into account. The U.S. has a pop. of 330 mil and has had 30 mil confirmed cases. Brazil has a pop. of 212 mil and has had 13 mil confirmed cases.
Their medical care is obviously worse than our (and/or their population has more unhealthy people to start with) but Brazil has had a far lower percentage of the population become infected in the first place.
That correlates with the state-by-state comparison in the U.S. that less restrictions results in less cases.
