Yesterday, Okinawa islands declared again a state of emergency, and Tokyo enforced a night curfew that was limited to night entertainment businesses in its central areas. You should think forward a next step that is to occur under very frivolous situations in Japan. Tokyo and its surrounding regions, Osaka and Kyoto, Nagoya have become epicenters of second pandemic, already. A daily-updated rate of the number of patients per week rises still modest, however chasing of first patients with the virus has become almost impossible. And, another season of flu approaches. Doctors and nurses are very worried of how they identify which is which in a case of fever. Anyway, we first face a difficult situation in which you cannot tell whether you are infected with which disease.
