For a lot more people to get it. And then have to tell healthcare professionals all their recent community activities, so that if the transmitter is still out there, asymptomatically transmitting, they can be found and notified. Maybe getting calls from public health workers to be told they're exposed and/or a transmitter.
Even then, since it's mostly the over 80's who are dying, it won't change the behavior of the under 50's much. Estimates on how much this will affect overall life expectancy vary, of course, but it's estimated the average 60 year old may end up living 5-9 years less than they would have (which will be measured by studying overall demographics and LE, of course). Men will lose a year more than women based on what we know right now.
But really, since only about 20% of people who get CV19 will have serious to severe symptoms, and only a tiny fraction overall will die, it may just become endemic and a common way for people over 75 to die. At the same time, promising treatments seem to be lurking here and there, so that younger people, especially have less to fear from this disease than they did.
Reasons the predictions of dire consequences didn't come true include massive efforts to find treatments and ventilators for everyone who needed them, and of course, the radical social distancing. Most places in the US have been spared high numbers of cases this late winter.
It'll slow during the summer (still lots of shut down measures) and then, we shall see. Care home residents are certainly still at risk.
My biggest fears are the toll it's already taken on healthcare workers, and it still hasn't rolled through more rural areas, where services aren't as strong. However, that won't produce the big media interest that NYC and NJ did, the sheer numbers are still absolutely mind-boggling.
