Alan,
"For mumps, you need 92 percent of the population to be immune for the disease to stop spreading entirely. This is what's known as the herd immunity threshold.
COVID-19 is, fortunately, much less infectious than mumps, with an estimated R0 of roughly 3.
With this number, the proportion of people who need to be infected is lower but still high, sitting at around 70 percent of the entire population.Sweden has 21,520 cases - for herd immunity they would need (Pop. 10,099,265)
6, 059, 559cases. At this rate this will be achieved in 281 months, which is 23 years.
