Anxiousnomore, I think most experts feel it will come back. And some think it has even been here for a while (more people having antibodies than they expected). Infectious disease even with a novel pathogen often follows patterns. An outlier scientist may have a theory that differs from the normal model and time will tell. But I am tending to believe this will be here in the future. We will have to get used to it being around and learn to live with it in our community like we do with other infectious viruses. I so hope they get to the point of effective vaccine sooner rather than later!

When AIDS started no one knew about it's infection rate so doctors were concerned then (as they are now are about Covid) about how widespread it would become in the early days. A Charlie Rose interview of the Surgeon General of the US (Koop) in the early days of HiV said something similar to what Y Ben- Israel says. He said it would die out somehow just like all other epidemics, and Koop also said he had no idea why this would happen. Black Death died despite no germ theory until the late 19th century which he cited. Not that any of these diseases prove Covid will die out, but I provide the article purely for those who take an interest in it, especially since Georgia is planning to end lock down this week and Sweden didn't lock down.
