This doesnt mean that we have a lesser chance of surviving if we acquire the corona virus. Actually, according to my Biology teacher, corona virus has been here for a lot of years already. The virus itself just evolves and mutate to another version of corona virus which is now identified as COVID19. We really don't have to be afraid to the virus itself if we know in ourselves that we are clean and we have a healthy lifestyle. Our body alone can fight it if we have a strong immune system. The problem with here is that the virus being contagious and it might infect those people who has weak immune system. As per the nervous system study, I don't think there is enough evidence for that considering that WHO and other health organizations hasn't release anything about it yet.
