At present, the epidemic has not been controlled, and the Olympic Games is an extremely densely populated activity. The host country of the Olympic Games should not only receive athletes from all over the world, but also receive tourists from all over the world. Obviously, once the Olympic Games are held normally, the imported cases in Japan can't be controlled unless you directly put an end to several countries with serious epidemics, but this is unrealistic. Secondly, the population density of opening ceremonies, sports events and gymnasiums is extremely high. In one case, the transmission speed is considered to be the highest. In addition, due to the increasing floating population in the Olympic Games, it is impossible to control relative isolation, or to uniformly stipulate that all spectators and athletes should be isolated for 14 days. People are willing to say that it is also a question whether Japan can arrange so many people.
Of course, due to Japan's huge investment in this Olympic Games, many people will think that it is unpatriotic for virologists to oppose reporting the competition. Actually, it's not. Patriotism is reflected in many aspects. Virologists are not worried about money, but about Japan's reputation. For the time being, no one can guarantee that everything will be calm in July, so Japan's willful behavior will definitely anger many countries. By then, it would be best if there were no cases or infections during the Olympic Games. If it happens, Japan will be blamed by the whole world. This is related to the national face and the serious image of Japan in other countries in the future. Virologists are naturally opposed.
So from an outsider's point of view, the virologist's objection is correct, which is hard to say for the Japanese authorities. However, according to the current date, instead of obsessing about whether the Olympic Games can be held, it is better to study the torch relay first. After all, it won't be long.
