Why do you want to test nucleic acid when you go back to work？ Can a cold affect the test results？ Disease control experts tell you!

Today’s Lantern Festival, after the Lantern Festival, even if the year is over, "migrant workers" will return to work one after another, and teachers and students will also enter the countdown to returning to school.

Sichuan disease control experts remind everyone that it is necessary to measure nucleic acid in time in order to reduce the risk of post-holiday epidemic spread.

So, where are we going to do it? What are the precautions?

1. Why do you want to do nucleic acid testing when you advocate returning to school?

Recently, the global COVID-19 epidemic continues to spread, and the domestic COVID-19 epidemic shows a multi-point distribution trend, with many local confirmed cases and asymptomatic infected people. The prevention and control situation is still severe and complicated. Our province is a populous province and a tourist province, with a large population density and a large floating population. On the one hand, a large number of migrant workers and tourists returned to Sichuan from all over the country during the Spring Festival, and on the other hand, a large number of people returned to Sichuan from outside the province after the holiday. In addition, during the Spring Festival, various gathering activities such as dinners and parties were frequent, and the mobility and gathering of people increased greatly, which greatly increased the risk of epidemic spread.

How to check the potential risks? Nucleic acid detection is the fastest and most convenient means. Nucleic acid detection is the primary measure to normalize prevention and control and implement the "four early" measures. Through nucleic acid detection, we can realize "early detection", directly find the evidence of the existence of the virus, and find the source of infection in time, thus blocking the transmission route and controlling the spread of the epidemic.

For example, on February 12, one of the two newly confirmed cases in Yunnan was found among active nucleic acid testers; On the evening of February 13th, among the patients in the fever clinic and the "willing to do all the tests" in Suzhou, four patients with positive results in the initial screening and recheck of nucleic acid detection were also found.

Therefore, in order to reduce the risk of post-holiday epidemic spread, ensure that there is no cluster epidemic, ensure everyone’s safety, and let everyone return to work happily, go to work with peace of mind, and go to school with peace of mind, it is suggested that everyone must do nucleic acid testing in time.

In addition, nucleic acid detection will not cause any harm to the human body. Only when collecting throat swab, the cotton swab will feel a slight foreign body sensation when it goes deep into the throat.

2. Who wants to do nucleic acid testing?

(1) Returned personnel

1. High risk positions

Front-line staff of customs, border inspection and port, aviation service personnel, staff related to imported cold chain food, staff in high-risk positions such as centralized isolation places and medical institutions should provide negative proof of nucleic acid detection within 48 hours when returning to work, and then conduct a nucleic acid detection within 24 hours after returning to work; If you can’t provide negative proof of nucleic acid test within 48 hours, you need to carry out nucleic acid test twice every 3 days (24 hours apart) after returning to work.

2. Key positions

Staff of disease control institutions, frontline staff of market supervision system, employees of farmers’ (bazaars) markets and supermarkets (excluding employees of imported cold chain food), employees of service industries such as take-away, postal service and express delivery, all employees and service personnel of transportation stations and service areas such as airports, railway (including high-speed rail) passenger stations and highway long-distance passenger stations, domestic transportation industry personnel, and grassroots epidemic prevention and control investigators, Service personnel of tourist attractions, song and dance entertainment places, staff of party and government organs and other state-owned enterprises and institutions, etc., should provide negative proof of nucleic acid detection within 48 hours; If you can’t provide negative proof of nucleic acid test within 48 hours, you need to conduct a nucleic acid test within 24 hours after returning to work.

3. Other returning workers are advised to take the initiative to do a nucleic acid test as soon as possible when they return to work, so that their families can rest assured and feel at ease!

(2) Returned students

Teachers and students of colleges and universities in the province return to school with negative nucleic acid test certificate and Sichuan Tianfu health pass green code within 48 hours before registration; If you can’t provide negative proof of nucleic acid test within 48 hours, you need to conduct a nucleic acid test within 24 hours after returning to school.

Teachers, students and employees of primary and secondary schools and kindergartens in the province and their family members who live together have no history of living outside the province or close contact with people who have returned to Sichuan from outside the province within 14 days, and they can return to school with the green code of Sichuan Tianfu Health. After the school checks the travel code of themselves and their family members who live together, it is not necessary to provide negative proof of nucleic acid test.

Teachers, students and employees of primary and secondary schools and kindergartens in the province or their family members who live together have a history of living outside the province within 14 days and a history of close contact with people who have returned to Sichuan from outside the province. When returning to school, they should provide negative proof of nucleic acid testing within 48 hours; If you can’t provide negative proof of nucleic acid test within 48 hours, you need to conduct a nucleic acid test within 24 hours after returning to school.

Personnel in key positions such as logistics management and temporary employment assistance in schools and kindergartens at all levels need to return to school with negative proof of nucleic acid test within 48 hours before registration and Sichuan Tianfu Health Pass Green Code, and schools should strengthen their normalized nucleic acid sampling monitoring.

3. Where to do nucleic acid testing?

In order to make nucleic acid detection more convenient, during the period of Spring Festival travel rush, on the basis of the conventional medical institutions for nucleic acid detection, a total of 672 convenient nucleic acid sampling site were added in the province. Among them, there are 13 airports; 55 train (high-speed rail) stations; 132 bus stations; 115 high-speed intersections; 23 scenic spots; There are 334 other squares and communities (townships). Provide timely and nearby nucleic acid sampling and testing services for people who are willing to complete the inspection.

Individuals who need testing can consult and make an appointment through WeChat and telephone, and choose the corresponding institution nearby for testing, or they can make inquiries through "Sichuan Tianfu Health Link", a popular service, medical and epidemic prevention institutions.

4. Where can I get the test results?

You don’t need to go to a testing institution to get a paper report, but you can directly pass the test results of nucleic acid and antibody through "Sichuan Tianfu Health Link", a popular service.

5. What are the precautions for nucleic acid testing?

(1) The "Sichuan Tianfu Health Code" should be scanned during nucleic acid testing and sampling. If there is no code, you need to bring your ID card, and the person’s ID card will be integrated.

(2)Try to avoid eating 2 hours before sampling to avoid vomiting and other discomfort; Try not to drink water or drink, smoke, drink or chew gum for 30 minutes before sampling.

(three)When sampling, try to reduce swallowing movements, swallow less saliva and not clear your throat.

(four)After sampling, leave the site as soon as possible, and wipe your hands with hand-free disinfectant or hand-free alcohol, sterile cotton pads, etc.

(five)Obey the arrangement and guidance of the sampling site staff, strictly implement the requirements of epidemic prevention and control, adhere to scientific norms to wear masks, keep a safe distance of more than one meter, and improve self-protection awareness and ability.

Tips

1. I caught a cold during nucleic acid testing. Will it affect the test results?

No. If the symptoms of upper respiratory tract infection are not caused by Covid-19, the kit can’t accumulate enough immunofluorescence, and the specific nucleic acid sequence of Covid-19 can’t be detected in patients’ samples, so there is no need to worry about being "misjudged".

2. Suffering from pharyngolaryngitis and phlegm in the throat will affect the test results?

No. The main causes of pharyngolaryngitis are recurrent acute pharyngitis, irritation of inflammatory secretions in nasal cavity, paranasal sinuses and nasopharynx, direct spread of chronic tonsillitis, stimulation of excessive alcohol and tobacco, dust, harmful gas and air pollution, and overeating spicy food. Covid-19 nucleic acid test is a specific test, which is a manifestation of Covid-19’s infection, so it will not affect the test results.

3. Did drinking wine the day before affect the test results? Do you need an empty stomach before testing?

Will not affect the test results, and do not need an empty stomach. However, it is suggested to avoid eating as much as possible before nucleic acid detection to avoid vomiting. Try not to smoke, drink or chew gum before sampling to avoid false negative results.
