The purpose of this study is to look at the safety and effectiveness of PAXLOVID in the real world and not in clinical studies. The study observes patients who have a high chance of getting severe COVID-19 in Korea.

This study is seeking participants who are:

* Patients with mild-to-moderate COVID-19 symptoms and at high chance of getting severe COVID-19, including hospitalization or death.
* Patients who received, are currently receiving, or are going to receive PAXLOVID according to locally approved label.
* Patients who have signed informed consent documents after understanding all the important parts of the study.

All participants are treated according to routine medical practice and there are no scheduled visits required by this study. All participants will be studied for a follow-up period of 28 days from the last PAXLOVID treatment to understand the safety and the effectiveness of treatment.
