The yellow code encoded by big data, if it meets the requirements of nucleic acid detection, will generally change back to green code after 3 days. If you can't change the green code in time, you can consult the local community or CDC about transcoding.
Immediately report to the local community (village) or county-level CDC, and actively cooperate with epidemiological investigation and follow-up epidemic prevention measures. If you have symptoms such as fever, cough, diarrhea, fatigue, and decreased sense of smell (taste), please wear a disposable medical surgical mask, go to a medical institution in time, and take the initiative to inform the doctor of his residence and contact history in the past 7 days. Go out for medical treatment and avoid taking public transport.
