As for COVID-19's mutation in Japan, in fact, as early as mid-June, COVID-19's mutation appeared in Japan, and now a large number of cases are infected after COVID-19's mutation. We don't fully grasp the variation and spread law of COVID-19, so for the people, we can only take all kinds of protective measures ourselves, and don't go to crowded and closed places. After all, there are still many asymptomatic infected people, so we should take precautions. If we relax our vigilance and ignore the protective measures, the number of confirmed cases may increase again. ?

Recently, a mutant COVID-19 was discovered in Japan. It is reported that on the 8th, the number of newly diagnosed cases in COVID-19 exceeded 1000. Because the virus will mutate to a certain extent in the process of spreading infection, a European variety has been found in many parts of Japan, and many viruses discovered later are derived from this variety. COVID-19 itself has a strong communication ability, and now it is a new type of variation. The national institutes of health of the United States conducted a study on this. They analyzed that the virus is likely to spread among young people, and these carriers have almost no symptoms, that is, such a new mutant virus will spread quietly among young people.

Compared with other countries, the number of people diagnosed in Japan is really small, but if we look at the population density in Japan, this situation is still quite serious. Japan is an island country with a small geographical area but a high population density. Therefore, population density is undoubtedly difficult to control. Compared with before, Japan has basically increased by dozens or hundreds. But in recent days, the number of new people has reached 1000 in just a few days. It seems that the previous stability is about to be broken and the situation may get out of control.
