Because the elderly and children can't produce the 72-hour nucleic acid certificate because they don't have a smart phone, if there are accompanying family members, they can produce it on their behalf. If it is true that the elderly and children travel alone, they must produce a printed negative nucleic acid certificate within 72 hours.
Access under the condition of Shenzhen subway;
Walking in various public places, entering the subway, high-speed rail, trains and other means of transportation, you must rely on a 72-hour negative nucleic acid test certificate. Take temperature measurement at the entrance of public places to check whether it is green code and whether there are stars on the travel card.
In terms of epidemic prevention and control, nucleic acid detection in Shenzhen Metro must be 24 hours or 48 hours. If the high-risk area in Shenzhen is reduced to a low-risk area, there is no need to produce a nucleic acid test certificate. In addition, there are only sporadic cases or no new cases. When Shenzhen subway station enters the station, you don't need to show the 48-hour nucleic acid certificate, as long as it is a green code.
When strict epidemic prevention control measures are promulgated, no matter where you go, you need to show a 24-hour or 48-hour nucleic acid negative certificate, a green code and a trip code. The epidemic situation is still active, so it is suggested to do nucleic acid testing when going out of the city and province.
