I contend that a lot of it probably has to do with fewer Africans eating processed food. They may be eating pawpaws or papayas infected with Covid, but they are eating fresh pawpaws or papayas.
The UK has its share of people with weight problems. I don't think continental Europe does so much. But I doubt many of their nursing homes are even up to the standard of our even our mediocre nursing homes.
Remember hearing somewhere that it is also effective against the Wuhan flu. Maybe I'm mistaken ... :^)
I’d bet Africa isn’t doing as well as reported. One thing that skews the statistics is that the U.S. ‘official’ reporting is much more thorough than virtually everywhere. This is why the U.S. has a higher newborn death rate than many countries. If a newborn takes a single breath and dies, he/she is counted. In some countries if a kid dies a week or two after birth, it is not recorded.
I seriously doubt that any nation in Africa has medical record keeping on a par with ours. People die from so many things in Africa and nobody is going to investigate the cause of death.
Kids are back in school here since early August. No problem. All are well.
Africa is doing better because of one thing: Malaria.
What is the treatment for Malaria: Hydroxychloroquine.
Africans in High Risk for Malaria environments have either taken or are taking the cure.
