I think a major difference between Swine Flu and SARS-2 is that it did not affect as many countries simultaneously as now, and, we did not see so many people ending up in the ICU. As I understand the numbers being: 10-20% end up in a hospital, 5-10% end up in ICU, half of them die. I don't remember anything similar for the 2009 pandemic.
