This is a slippery slope: If you put restrictions for entry from a country that has a history of diseases (all of Africa, most of Asia, Central and South America), it would include all of your own citizens returning from their trips to the said regions, as well as travelers from all other countries that do not impose such draconian rules. That’s why the travel restrictions are in place during active pandemic, but not when diseases become endemic for these regions.
We all need to practice precautions but, unfortunately, some of us are selfish, careless, or not smart enough to know the difference. Look at the World we are living in.
And freedom does not mean that if you are dumb enough you could contract a highly contagious disease and then freely spread among those for whom it could be deadly.
