Why are the numbers infected with Covid-19 different from a geographic point of view? the number of people infected is not widely distributed in Africa, is it the opposite in the rest of the world especially in america and europe?
Although the muntant SARS-CoV-2 may be one of the reason, but the stark reality is that most of the countries are hiding being not doing enough tests.
When more tests are done, more COVID-19 cases are detected, and more COVID-19 deaths are noted. This happening for example in India, Brazil, Mexico, and now in South Africa.
There may be various factors to be considered
1. Weather condition
2. Eating habits
3. Dense areas are more prone to diseases as compared to sparse
4. Hygiene habits
5. Literacy rate
6.Spiritual progress of people living in a particular area also matters a lot
It's simple, I think that the number of cses tested in Europe and America is very high compared to thr cases tested in Africa and moreover in africa there is little air traffic.
