Scientists can not determine if Covid-19 is ever going to get out of our lives. They are looking at other mutations and they also compare this deadly virus with other contagious infectious.
For example, respiratory syncytial virus (RSV) is a pathogen that might look alike Covid-19. Most people get infected with RSV in the first two years of their lives. This pathogen can cause hospitalization of little children, but most of the cases have mild symptoms.
Waning immunity and viral evolution are giving RSV the possibility to go across the world each year, infecting several adults. However, the symptoms are not severe, due to childhood exposure. If SARV-CoV-2 follows RSV’s path (with the help of vaccines as well), it can be transformed into a virus of kids, as Andrew Rambaut, an evolutionary biologist at the University of Edinburgh, UK says.
