Scientists believe that the virus that causes “Covid-19” may have been with us for decades or more, but this does not mean that it will continue to pose the same threat..
And a virus appeared SARS-CoV-2 At the end of 2019 and it is difficult to predict its long-term behavior. But many experts believe it is possible for the illness to eventually go from a crisis to a nuisance like the common cold.
This will happen when people acquire immunity over time, either through infection or vaccination, as other viruses follow a similar path..
The 1918 influenza pandemic could also provide clues to the potential Covid-19 pathway..
The US Centers for Disease Control and Prevention estimate that a third of the world’s population has been infected with this virus, which originated in birds. Ultimately, after infected people died or developed their immunity, the virus stopped spreading rapidly. It later morphed into a less aggressive form, which experts say continues to spread seasonally..
However, the emergence of new variants of “Covid 19” may complicate the picture if future mutations of the virus cause more serious disease or evade vaccines..
It is unlikely that the virus will be completely eliminated, given the possibility that people will be infected again after being sick or vaccinated..
The only virus that has been eradicated from humans is smallpox. This is because people develop long-lasting immunity to this virus after illness or vaccination..
It is not clear how future mutations will form. SARS-CoV-2 The current course of the disease..
With the appearance of new variants, some of them more infectious, others more virulent and possibly less sensitive to vaccines, scientists are reminding how much they still do not know about the future of the virus.
