Diseases can change and mutate through the years. With COVID-19, the way we interact with the virus may change dramatically over decades. We have already seen mutations of the SARS virus with the Delta and Omnicom variants. There may be more variants in the future. People must get vaccinated so that we can be better prepared to fight off future variants.
On the other hand, as time goes on, we also understand the virus. For example, the CDC thought COVID-19 may be contracted by a fomite transmission, but we now know that this is untrue. In the Middle Ages, the bubonic plague wiped out almost 1/3 of the world's population. Still, as time has progressed, the bubonic plague no longer haunts us. I think that COVID can follow this trend as technology and knowledge advance. We also will be able to study the disease and create new and better treatments as time goes on.
Three factors that change SARS-Cov-2 are mask-wearing, vaccination rates, and government policies. When people wear masks and are vaccinated, they change the trajectory of the rates of COVID dramatically. When governments do not or cannot implement good practices to stop covid, it can dramatically increase the transmission rates of COVID.
