The Hubei Provincial Center for Disease Control and Prevention issued a health reminder on April 11: the urban areas where the cities without local epidemics are located , entering and leaving communities, communities, urban villages, enterprises and institutions, and various public places, and taking public transportation, etc., a 72-hour nucleic acid test negative certificate must be provided; there are local epidemic areas in urban areas, entering and leaving communities, communities, urban villages and enterprises and institutions Units and various public places, taking public transportation, etc., must provide a 48-hour nucleic acid test negative certificate; other areas and prevention and control areas such as closed areas, control areas, prevention areas, and medium and high-risk areas abide by the current nucleic acid testing policies.
Reminders from Hubei CDC experts: under the current policy , It is recommended to carry out nucleic acid testing in time to ensure smooth travel.
For this reason, many residents and friends have asked questions:“I have done several nucleic acid tests, why do I need to do it again?”
This virus is unusualRecently, most of the confirmed cases of new coronary pneumonia in China are Omicron variant strains. Compared with the delta strain, the Omicron variant strain has a shorter incubation period, stronger infectivity, and faster transmission speed. Moreover, many residents have no obvious symptoms after infection, and are highly concealed, and are more likely to be scattered or concentrated in multiple locations. Nucleic acid testing is currently an important way to detect infected people at an early stage. Faced with the “unusual” Omicron, it is necessary to carry out population nucleic acid testing as soon as possible to screen infected people, so as to cut off the transmission route as soon as possible and avoid the spread of the epidemic. One trick is hard to do< span>If you want to pass a nucleic acid test, you need to find all the infected people or the source of infection. It is difficult to win with one trick. This is Because of the possibility of false negative results. 1Virus SuppressedIndividuals infected with Omicron mutants, human The immune system will quickly start the challenge, and the number of viruses in the body will show a fluctuating state. If the immune system prevails at the time of sampling, and the infected person has a low amount of virus, a positive result may not be detected. 2with The incubation period of Omicron is related tothe incubation period of Omicron is mostly in About 3 days, it takes a certain time from infection to detection, and it is necessary to dynamically and repeatedly detect nucleic acids in a short period of time to be able to detect it quickly and effectively. Multiple detections with high accuracyThe accuracy of one nucleic acid detection is lower than that of multiple nucleic acid detections. Currently, for the Omicron variant, it is necessary to dynamically and repeatedly detect nucleic acid in a short period of time to effectively detect it. The purpose of speeding up encrypted nucleic acid testing is to find out “fish that slip through the net” from tens of millions of people to prevent the spread of the epidemic. It does not mean that the current epidemic situation is very serious. Disease control experts reminded that in the face of multiple short-term nucleic acid testing arrangements, the public does not need to panic, and should actively cooperate at the moment, follow the precautions for nucleic acid testing, and conduct all inspections. Prevention Tips: Pay attention to nucleic acid testing Good personal protection※ Actively cooperate. Follow the guidance and tips of the staff and prepare the WeChat “Wuhan Epidemic War” applet in advance The “health code” in the , patiently wait in line. In order to avoid vomiting and other situations during sampling, try not to eat for 2 hours before sampling; to avoid affecting the test results, do not smoke, drink or chew gum 30 minutes before sampling. ※ Wear a mask. Disposable medical masks or medical surgical masks should be worn throughout the entire process. Children should wear special masks suitable for children. The masks should fully fit the face and cover the mouth and nose.< /span>※ One meter apart.When queuing up for nucleic acid testing, keep a distance of at least one meter from the front, back, left, and right to avoid crowds chatting.※ Matching sampling.During the nucleic acid sampling process, when the person in front has just finished the collection, the person behind the sample should not sit down in a hurry, let alone take off the mask immediately, keep a safe distance, and wait for the doctor to finish the previous sampling, complete the hand disinfection and take out the new one. After the cotton swab, sit up and sit up quickly. Correctly cooperate with the sampling action to reduce discomfort. Try to relax as much as possible and keep the top of the head back to facilitate smooth sampling.※ Civilized etiquette.Cough , Sneezing will produce droplets with bacteria or viruses, and throat or nose discomfort may occur during the collection process. Remember not to cough or sneeze at medical staff or others, and cover your mouth and nose with a tissue, handkerchief or elbow. ※ Leave as soon as possible.After the sampling, wear a mask immediately, leave the sampling site as soon as possible, and do not stay too long or ask the sampling personnel about the results. The nucleic acid test results are usually It can be inquired within 24 hours, sometimes it will be delayed due to the large amount of testing, please be patient Heart waiting. Pay attention to hand hygiene before and after nucleic acid testing, and use hand sanitizer to wipe your hands.
