Huh? The virus has not "gone," except perhaps in places that implemented actual lockdowns (not just stay at home orders) and maintain strict travel restrictions, like China.
For comparison: China's population is 136 times that of Sweden [1] and it has had fewer COVID deaths in absolute terms than Sweden (4,634 vs 5,846) [2]. Even assuming the true figure in China is 10x what the official number is, that's still far fewer deaths per capita. If China has had an equivalent per capita dealths, it would have had 800,000 dead from COVID [3].
