Neocoron refers to a new coronavirus, and the omicron strain is a mutated strain of neocoronavirus. The differences between omicron and neocoronavirus are incubation period, transmission, and infectivity. 1. Incubation period: Omicron has a shorter incubation period than the initial New Crown strain. 2. Transmissibility: Omicron is more transmissible than the initial New Crown strain. 3. Contagiousness: Omicron is much more contagious than the initial new crown strain. Do not go out during the outbreak if you don’t have to. If you have to go out, pay attention to protection and wear a good mask, the virus can be spread through droplets. If there are symptoms such as sore throat, cough, runny nose, fever, nausea, vomiting and other symptoms, and there is a dense situation with confirmed cases, you need to promptly conduct nucleic acid testing, self-isolation, and timely reporting to the relevant departments.
