One: The newly confirmed population infection cases in Heilongjiang 16 cases, asymptomatic 12 cases. The confirmed cases are mainly from Wangkui County, mostly villagers in Huiqi Village. At present, Wangkui County has completely closed the city, conducted nucleic acid tests on all villagers, confirmed more infected people, and isolated and controlled the close contacts of the confirmed personnel. People in Wangkui County were forbidden to leave without permission to prevent COVID-19 virus from spreading to other areas.
Two: Vaccination At present, there is no effective treatment method that can quickly detect COVID-19 in the world, so vaccination is the only correct way to prevent COVID-19 from rapid infection. As we all know, when people are infected with the virus and are cured, corresponding virus antibodies will appear in the body, and the immune system will destroy the virus itself the next time the virus invades. Only when the vast majority of people in society have antibodies can we form an effective crowd immune barrier and prevent COVID-19 from infecting each other in the crowd, resulting in group infection. Since the end of 2020, COVID-19 has been found all over the world. This study shows that the mutated COVID-19 virus is more infectious, and it also shows that the current COVID-19 vaccine is still effective against the mutated virus. Therefore, large-scale vaccination should be carried out as soon as possible, and an effective population immune barrier should be formed as soon as possible to prevent the spread of COVID-19 in the population.
Three: What should we do? Before mass vaccination, we should continue to maintain daily epidemic prevention measures. Wear a mask when you go out, wash your hands frequently and exercise more, don't kill wild animals, go out less, don't meet and have dinner together. Once you find COVID-19's infection symptoms, you should seek medical advice in time and report truthfully. Recently, a local group infection occurred in China, and it is very likely that this wave of virus was imported from abroad. Therefore, airport customs and other units should strengthen epidemic prevention measures, carry out nucleic acid detection and isolation control on foreigners, and release imported goods after comprehensive disinfection. For vaccine manufacturers, it is necessary to increase the output as much as possible, strive for more people to be vaccinated, form an effective population immune barrier, and prevent the vaccine from losing its effect on COVID-19, which will mutate in the future. Since the end of 2020, local people have been infected all over the country, which shows that our war against epidemic has not been completely won. Once we relax, COVID-19 will make a comeback. We should try our best to keep this hard-won anti-epidemic achievement.
