Slight difference is that this disease is fifty times more deadly than the HK flu. Just about everyone in the US got that one and about 50,000 people died. We are at 5 times that level already and only 10% of the population has been exposed. (Also the value placed on old people’s lives has increased drastically... you might not like it but it is social consensus to spend millions to extend the lives of 75-year-olds by a few more years. )
