Goaguy Thanks for the additional information on Tanzania. According to the "official" numbers Tanzania has less than 30 deaths related to covid-19. And less than 600 cases ever recorded. It's suspected that many people within the African continent may be naturally immune to the disease because of prior antiviral drugs taken for other ailments. It's only a guess right now. Hope they do some serious research to find out. I've added Tanzania closer to the top of my travel list now. Thanks again!
