More tests, more positives. Fewer tests, fewer positives. We are #1 in tests. Remove totalitarian regimes from the equation they put out more fake news than us. Poor countries, give them some slack they have trouble distributing basic medicines. Though India is pretty good with medicine they still have their poverty issues.
So people don't know when they are ill?
After a test, to know if one is ill because one can't tell, one will always need that next test to be sure, for each day passes, and "tomorrow is another day" with other opportunities to be ill, because now being without symptoms means you too can be ill. But only with Covid. What about influenza tests? Pneumonia tests? Other respiratory illness tests?
Time to invest in test makers. Or stop worrying.
