There are generally three patterns of health codes, red, yellow and green.

The first one is green, which means that I have not been exposed to the polluted environment in Covid-19 before the data update date. I suggest you wear a mask when you go out, change clothes and wash your hands when you go home.

The second color is yellow, which means that I may have been exposed to the polluted environment in Covid-19 in the past 14 days. The CDC reminds you to contact the local community health service center or the CDC, try not to go out in the near future, keep a certain distance from your family, and take your temperature twice a day.

In case of any discomfort such as fever, fatigue, cough, diarrhea and conjunctivitis, put on a mask and go to a nearby medical institution for treatment at the first time, and take the initiative to tell the doctor about the possible exposure history.

The third color is red, which means that you have had close contact with patients in COVID-19 in the past 14 days. You should contact the local community health service center or the Center for Disease Control and Prevention as soon as possible to accept centralized isolation medical observation.
