Newly mutated strains of Neo-Crown virus commonly include Beta, Delta and Omicron. 1. Beta: It is one of the new mutated strains of Neocoronavirus, it will have a mutation in the spiking protein, which may lead to immune escape, which means that the antibodies that have been previously infected or injected may have less and less effect on the Beta strain. 2. Delta: a new mutated strain of Neocoronavirus, Delta has a short incubation period, rapid transmission, high viral load, long nucleic acid conversion time, and is more likely to develop into critical illnesses, among other things. 3. Omicron: It is a mutated strain of the new coronavirus, which has a fast transmission speed, strong concealment, strong penetration, and its mutation amount is larger than that of the delta strain, which is easy to cause secondary infection. The new mutant strain of the new coronavirus spreads very quickly, usually try to avoid going to crowded places, wear a mask when you go out, pay attention to wash your hands when you get home, and exercise properly to enhance resistance.
