①Those receiving home treatment, overnight stay treatment, or inpatient treatment (excluding cases treated with ventilators, etc.), may return to work after 7 days have passed since the onset date and 24 hours have passed since the symptoms lessened (the treatment is lifted from the 8th day).
Furthermore, the number of days elapsed is calculated from the day of symptom onset as 「day 0」. For the 24-hour lapse after alleviation of symptoms, it is defined as 「at least 24 hours must have elapsed without the patient having taken any medication to alleviate symptoms」.

②Those who are currently hospitalized (on the 8th day after 7 days have passed) may be released from treatment from the 11th day if 10 days have passed since the onset date and 72 hours have passed since the symptoms abated. If there are any instructions (verbally) from the attending physician regarding the patient's return to work at the time of discharge, please follow such instructions. It is not necessary to ask the doctor for a Certificate / Proof of recovery from COVID-19.

(2) If the patient is asymptomatic and has no symptoms of any kind during the course of the treatment.
If 7 days have passed from the date of specimen collection, the patient can be released from treatment on the 8th day. In addition, if the antigen test using an approved test kid as the in vitro diagnostic kit on the 5th day is confirmed negative, the patient can be released from treatment after 5 days (on the 6th day). Also, please take a picture of the negative result to prove that the test was conducted using an approved test kit (in-vitro diagnostic).

※Symptomatic patients remain at risk of infection for 10 days, and asymptomatic patients remain at risk for 7 days. As such, we ask that you check your own temperature and other health conditions, refrain from contact with high-risk individuals and activities that carry a high risk of infection, and perform infection-prevention activities.

※Regarding self-restraint from going out during the treatment period, if a patient is symptomatic and 24 hours have passed since the symptoms lessened or if the patient is asymptomatic, it is acceptable to go out to buy groceries and contact with people provided that only for a short time, refrain from using public transportation, and take voluntary infection prevention measures such as wearing a mask at all times.
