An Imperial police officer, member in department 2 which escorts Prince and Princess Hitachi, has COVID-19. The man in his 50s has not been in contact with the couple for over 3 weeks since he accompanied Prince Hitachi on a private visit in late June. The officer's duty was only a few hours and everyone wore face masks. The Hitachi couple do not have symptoms.
The man and his family were found to be infected on July 7; the family did not go to work (self-isolating?) since July 6 when they took the PCR tests. The officer retook the PCR test on the 16th which returned as positive on the 17th but has no symptoms.
