Because you have been in the area near key places, you may have been exposed to confirmed cases and asymptomatic infected people, so it will turn into a yellow code. Sukang Code was implemented in Jiangsu Province during the epidemic prevention and control in COVID-19. People who have entered and returned to the Soviet Union and those who work, study, live, travel or stay temporarily in the Soviet Union need to apply and use it. The health code classifies people according to different risk levels of red, yellow and green (corresponding to high, medium and low respectively), which is recognized by the whole province and the three provinces and one city in the Yangtze River Delta.
Coding rule of Su Kang code: 1. Red team personnel: Confirmed cases and suspected cases treated in isolation in designated medical institutions; Asymptomatic infected persons who are undergoing medical observation in designated medical institutions; Close contacts of confirmed cases, suspected cases and asymptomatic infected persons in medical observation; Personnel in key epidemic prevention and control areas and high-risk areas.
2. Code yellow personnel: personnel from epidemic danger areas; Home observation of the cured confirmed cases or asymptomatic infected persons less than 14 days; People with fever, dry cough, shortness of breath, fatigue and respiratory symptoms.
