Scientists conclude people cannot get coronavirus twice

The CDC added that unlike other viruses, such as HIV and chickenpox - which can break into the nucleus of human cells and stay latent for years before reactivating - the coronavirus stays outside of the host cell's nucleus. "This means it does not cause chronic infection or recurrence," explained Dr Oh Myoung-don, the head of the CDC committee, meaning it is unlikely for patients to relapse in this fashion.msnNews
