As of December 17th, Guangzhou, the official standard version of epidemic prevention requirements for all low-risk people entering Guangzhou in the whole region is as follows: * * * The &”;centralized isolation for 14 days&”; (counting from the area where they leave the prefecture-level city, union, state and municipality directly under the Central Government, the same below) will be carried out on the 1st, 4th, 7th, 10th and 14th days. * * * Carry out &”;home isolation for 14 days&”; for those who have lived in medium-risk areas (or need to refer to the management of medium-risk areas after evaluation), and carry out nucleic acid testing on the 1st, 4th, 7th, 10th and 14th days. * * * Carry out &”;home isolation for 7 days and home health monitoring for 7 days&”; for the residents who have lived in the prefecture-level cities (districts of leagues, prefectures and municipalities directly under the Central Government) where there are high-risk areas (or those that need to be managed with reference to high-risk areas after assessment), and carry out nucleic acid detection on the 1st, 3rd, 7th and 14th days. * * * Carry out &”;three-day two-check&”; (24-hour interval) and 14-day home health monitoring on the residents who have lived in prefecture-level cities with local positive cases (districts of autonomous regions, prefectures and municipalities directly under the Central Government), and do a nucleic acid test on the 7th and 14th days respectively. * * * For those who come (return) to Guangzhou from other provinces (autonomous regions and municipalities directly under the Central Government) in China, do a nucleic acid test at the airport, railway station or nearby as soon as possible within 24 hours after arriving in Guangzhou, and monitor their self-health for 14 days. * * * Other provinces (autonomous regions and municipalities directly under the Central Government) should take the initiative to do a nucleic acid test within 48 hours after arriving in Guangzhou. Therefore, as long as you come from a low-risk area in China, keep the epidemic prevention health code and itinerary code completely green without star marks, and the temperature measurement is normal, you can travel along Guangzhou without affecting your travel. Normal negative nucleic acid test medical report within 48 hours is a necessity, and it is needed for cross-provincial travel, so it is good to take it before going out.
