Guanyun Dongxia Expressway needs to hold the green health code and negative certificate of nucleic acid test within 48 hours, and carry out 1 nucleic acid test nearby within 12 hours after irrigation arrives. Nucleic acid can flow in order only after it is negative. Need to have a green health code, travel itinerary has no history of living outside the province. Take protective measures during irrigation, report to the community and village after irrigation, and do self-health monitoring for 7 days. If you have fever, cough and other symptoms, please go to the fever clinic in time and report to the community and village. Due to the need of epidemic control, Jiangsu Gao Xia Expressway still needs Su Kang code, trip code and temperature measurement, and it is no longer necessary to provide 48-hour negative account certificate. Although high-speed control has been gradually relaxed, personal epidemic prevention is still essential, which is not only a support for epidemic prevention and control, but also a responsible behavior for individuals and families!
