One: the British epidemic. When investigating the case of COVID-19, the British Public Health Bureau found a new mutation called E484K. This virus mutation has been found in South Africa before, but it has only been found in some parts of Britain at present, which does not mean that the mutated virus has been widely existed. Experts said that the COVID-19 vaccine currently used is still effective against this mutant virus. The local government also called on people to strictly abide by the blockade regulations, try not to go out, and avoid being infected with COVID-19 virus to prevent COVID-19 from further mutating.
Two: After vaccination, people infected with the virus will generally produce corresponding virus antibodies in the body after being cured. When the virus invades again, the immune system in the body will find and destroy it. Only when most people in the society have antibodies in their bodies can COVID-19 be effectively prevented from being transmitted from person to person, and a population immune barrier can be truly formed. There is no rapid detection and effective treatment for COVID-19 in the world, so vaccination has become the most effective way to prevent COVID-19 infection. Mutated COVID-19 has been found in many parts of the world, and mutated COVID-19 is more contagious. Related research shows that COVID-19 vaccine is still effective against mutated COVID-19. Therefore, we should carry out large-scale vaccination before the COVID-19 vaccine fails, so as to form a truly effective population immune barrier as soon as possible to prevent the occurrence of COVID-19 infection, which will seriously affect our normal production and life and social and economic development.
3. Daily epidemic prevention Our daily epidemic prevention measures need to be maintained before large-scale vaccination forms a truly effective population immune barrier. Wear a mask when going out, wash your hands frequently, have plenty of ventilation, don't kill wild animals, go out less, don't meet each other, and don't have dinner together. Once you have symptoms of COVID-19 infection, you should seek medical advice in time and report truthfully. After investigation, COVID-19 infection in some parts of China is probably imported from abroad. Therefore, airport customs and other relevant units should strengthen nucleic acid detection and safety isolation control for foreigners, and fully disinfect imported goods before releasing them. Since the end of 2020, the epidemic situation in COVID-19 has rebounded, warning that once our epidemic prevention work is relaxed, COVID-19 will make a comeback, and we should strive to adhere to this hard-won anti-epidemic achievement throughout the country.
