TV Asahi reported that the National Institute of Infectious Diseases announced the results of its analysis of the DNA of the new coronavirus, which found that while Japan was able to contain the first wave of the virus from China, it failed to prevent the influx of the second wave from the U.S. and Europe, which led to the spread of infection. The network said the DNA of the new coronavirus is repeatedly going through small mutations in a short period of time, adding that these small mutations can be used as fingerprints to trace the routes of infections. According to the network, the virus found in Japan between January and February had DNA similar to the virus from Wuhan, but since mid-March many versions of the virus from Europe that had gone through several mutations were confirmed in Japan. The network said the institute’s analysis shows that although Japan was able to successfully contain the first wave from China and put an end to the virus outbreak on the Diamond Princess, it was unable to stop the influx of the second wave of the virus from the U.S. and Europe by mid-March, pointing out that the virus spread across the nation within a few weeks after that. The institute reportedly predicts that third and fourth waves are inevitable.
