Now, the world is worried about the spread of Japan's new crown

Author: Wang Fang has taken strict anti epidemic measures all over the country At present, the epidemic situation of new crown in China has been effectively controlled The number of new cases in other areas of Hubei Province has been reduced to one place, and the number of cases in many areas has achieved zero growth However, in Japan, which is one sea away from us, the development of the new crown epidemic is not optimistic According to Xinhua News Agency on February 19, the total number of confirmed cases in Japan has reached 704, 322 of the 621 confirmed cases on the "Diamond Princess" are asymptomatic With the increasing number of confirmed cases, the world has turned its attention to Japan "Diamond Princess" or "virus maker" on February 19, science, a top international journal, published a news report, in which Japanese infectious diseases expert Kentaro Iwata was interviewed Iwata said he was quarantining himself in a hotel to avoid infecting his family At the same time, he also admitted that Japan has missed the opportunity to answer important epidemiological questions about the new virus and the diseases it causes It is because of the lack of these reports that it is impossible to judge whether the cruise ship has secondary infection after taking isolation measures Doi: 10.1126/science.abb3761 earlier, a man got off the ship in Hong Kong and found to be infected with sars-cov-2 On February 2, after learning the news, the Japanese authorities decided to isolate the cruise ship carrying 3700 passengers, so as to avoid the spread of the epidemic in Japan Passengers with positive test results can be taken out of the ship for isolation and care However, on February 18, Iwata broke through many obstacles to board the cruise ship and found that things are moving in an unsettling direction The cruise ship has become a "virus maker" After being forced to leave, Iwata released a 12 minute video that night, describing what he saw and heard on the ship: there were many loopholes in the anti epidemic work on the mail ship, there was no difference between the uninfected "green area" and the potentially infected "red area" People on the ship could walk around at will without taking protective measures Some medical staff said that He has been infected but has given up taking measures to protect himself There are no professionals on board, and officials of the Ministry of health, welfare and labor (hereinafter referred to as the Ministry of health and social security) are reluctant to listen to his opinions The Japanese scientist, who helped fight against the Ebola virus and cholera outbreak in Africa and faced the SARS epidemic in China in 2003, admitted that he was never afraid of infecting the virus because he knew how to protect it, but when he stood on the diamond princess, he was afraid that he would be infected The Japanese government responded to the video comments that the day before Iwata boarded the cruise ship, Japanese public health expert Shigeru Satsuma defended the quarantine measures at a press conference on Monday: the measures taken at that time were completely correct Although the crew and those sharing the cabin may have contracted the virus on board, the data he provided showed that most passengers had been infected before quarantine began It is worth noting that these data only cover the first 168 sick passengers and crew members Three days later, Japan's chief cabinet secretary, Kan Yiwei, refuted Iwata's comments at a press conference on February 19, saying the government had taken measures to prevent the epidemic from further expanding In addition, Mr Qiao Benyue, Vice Minister of houlao Province, also attacked Iwata, saying that "there is no such thing", and those remarks "are only his personal opinions in the end" However, as the outbreak on the Diamond Princess intensified, the official Japanese statements did not seem to convince other countries The CDC has warned that quarantine measures on the Diamond Princess may not be enough to prevent the spread of people on board At present, the United States, South Korea, Canada, Australia, Australia and other countries have successively withdrawn overseas Chinese from cruise ships, and most of the people who have been returned to China are required to accept another 14 days of isolation On February 20, Iwata deleted the video, saying it did not want to cause further controversy, and apologized sincerely to those who were troubled by the incident The flag country of the cruise ship is the UK, and the difficulty of anti epidemic work increased on February 19 When people accused the Japanese authorities of taking anti epidemic measures against the cruise ship, the famous Japanese media Nikkei news commented that the cruise ship's nationality is Bermuda, and the cruise ship should be under the jurisdiction of the UK In other words, Japan is in fact "back pot" According to the "flag state doctrine" in international law, ships on the high seas are applicable to the "exclusive jurisdiction" of the flag state As a flag state's obligation, it stipulates "the effective exercise of jurisdiction and supervision over its administrative, technical and social matters" The flag country of the "Diamond Princess" is the UK, so there are principles that cannot be applied to Japanese laws and administrative power, which to some extent makes the response to the epidemic very complicated In addition, Japanese government officials said, "it could have refused to dock the cruise ship." But from a humanitarian point of view, this approach is clearly very cruel In fact, judging from the current situation, whether Japan is "wronged" is not so important The most important thing is to take effective measures to curb the spread of the epidemic But judging from the situation of the diamond princess, this response is obviously a failure The first passengers to disembark can move freely People are worried about the spread of the epidemic On February 19, the first 500 passengers with negative nucleic acid test results were approved to disembark The passengers with positive test results will be sent to the hospital for treatment It is expected that by the 21st, all the people on board will disembark Japanese officials said there was little evidence of a false negative test and that the passengers had no need to be quarantined after disembarking Although the government will track the situation of these passengers after getting off the ship, this treatment still makes many Japanese people uneasy It is understood that these passengers will be sent to various transport hubs by special buses, and then take public transport to go home by themselves, that is to say, they are very likely to contact with the crowd According to Zhou Weisheng, a professor at Ritsumeikan University in Japan, from the nosocomial infection of "Diamond Princess" and Youtian hospital in Wakayama County, as well as the infection of medical staff, the rapid infection in the hospital should be paid great attention to and the risk of infection of high-density groups of people should be strictly prevented According to this trend, the number of domestic infections in Japan is likely to double in the next week Therefore, from a statistical point of view, it is possible to rapidly infect the whole country of Japan if it is not strictly controlled urgently " "Virus has no borders" on February 20, a spokesman of the Chinese Embassy in Japan said in response to a reporter's question that after learning that Japan's new coronavirus nucleic acid detection reagent is insufficient, China has donated a batch of new coronavirus nucleic acid detection kits to the National Institute of infectious diseases of Japan through China Shenzhen Huada Gene Technology Co., Ltd and Shenzhen mammoth foundation At the same time, he also said, "viruses have no national boundaries and need to be addressed by the international community."
