Remember when the USA and other countries banned travel from China when the Covid 19 disease first hit. Remember that people in China would fly to another country like Britian and then fly to the USA and bring Covid 19 with them? I sure do.

Now we have a new Omicron variant of Covid19 found in Southern Africa and we are banning flights from those countries to the USA. But still nothing is stopping people in South Africa from flying to another country and then flying from there to the USA. We have not learned any lessons.
