Please refer to the following when judging close contacts at hospitals and welfare facilities.

  • Insufficient PPE (personal protective equipment) or hand sanitizer
  • If neither of you is wearing a mask

If you have contact with a positive person but are not a close contact person, we recommend that you observe your health for 7 days after contact.
