Since the end of July, COVID-19 has been scattered everywhere. Universal COVID-19 nucleic acid detection has been opened in many parts of the world. After several rounds of nucleic acid sampling and testing, many citizens have some doubts. What are the differences between nasopharyngeal test and oropharyngeal swab sampling?

  • What are the ways of sampling the nucleic acid of the SARS-CoV-2?

nucleic acid samples collected through the nasal cavity are called “nasopharyngeal swabs”. Samples collected through the mouth are called “oropharyngeal swabs”. Both are the main ways to collect samples from COVID-19 nucleic acid detection. In addition, there are deep expectoration fluid, nasopharyngeal or respiratory tract extract, bronchial lavage fluid, and alveolar lavage fluid.

  • how to choose nasopharyngeal swabs and oropharyngeal swabs?

Whether to choose nasopharyngeal swabs or oropharyngeal swabs, mainly follows the following principles: first, according to the eighth edition of the prevention and control plan and the second edition of COVID-19 nucleic acid testing manual, the first choice is to collect nasopharyngeal swabs while collecting nucleic acid samples. Secondly, asymptomatic infected persons, entry personnel and close contacts should collect nasopharyngeal swabs during isolation observation; Third, due to the relatively simple operation of oropharyngeal swabs, more oropharyngeal swabs should be collected when nucleic acid detection is carried out in low-risk areas.

  • why should nasopharyngeal swabs be collected first?

The study shows that the detection rate of COVID-19 nucleic acid in nasopharyngeal swabs is higher than that in oropharyngeal swabs, because the nasopharyngeal cavity is relatively closed and the virus is easier to accumulate. Secondly, the sampler can stand behind the patient’s side. The patient only needs to expose his nostrils, and there is basically no pharyngeal reflex. The exposure risk of the sampler is lower and safer than that of the oropharyngeal swab. However, whether it is oropharyngeal swab or nasopharyngeal swab, the key is that the collection action should be standardized, in place and meet the standards. As long as the collection is standardized, both methods can achieve the expected detection purpose.

French Prime Minister Fidel Castel introduced the situation of the French epidemic at a press conference on the 12th.

Two weeks later, France formed a new epidemic prevention committee to evaluate the outbreak of the blockade.

At a press conference held at 18:00, French Prime Minister Castel said that some indicators showed that the epidemic situation in France had improved, but it was not suitable to relax restrictions.

According to the report of Figaro newspaper, Castle said the outbreak of COVID-19 had a great impact on human health. Now 1/4 of Frenchmen die in COVID-19. So that all those in need can get treatment.

However, the restart of the blockade has achieved results, and the daily new patient curve slowed down within a week, down by about 16%. That could be the turning point of the outbreak. Next week, the medical system may reach the second peak of the outbreak. After that, the number of hospitalized patients will decrease.

Jean Castel warned that the improvement in current epidemic data should be explained in a “positive and cautious” way. Lifting restrictions is irresponsible.

The current restrictions will be maintained for at least 15 days, including the prohibition of non essential transactions, and the continued closure of restaurants and stadiums.

Castel stressed that the government does not want to repeat the blockade measures for the first outbreak of the epidemic this spring, which has led to the stagnation of the country’s economic, social and educational life.

The results of the second blockade will meet expectations. Next, the government will continue to provide large-scale support to enterprises and job seekers. The solidarity foundation will issue unemployment benefits as soon as possible and extend them after they expire. The university town will also mobilize to help poor students and create 1600 student employment opportunities in November, December and January 2011.

Carry forward the spirit of citizenship and make unremitting efforts during the blockade.

At the same time, the authorities asked the Ministry of the interior to strengthen supervision, especially in major cities such as Paris. The French can spend Christmas and year-end holidays with their families. He stressed that he hopes this rule can reach some strict restrictions. It is impossible to expect dozens of people to get together or hold a large celebration on New Year’s Eve.

At the press conference, French health minister Olivier viran, education minister Branke blanch, labor minister Elizabeth Bruno Bernard and economic minister Bruno lemier attended the press conference.

Olivier walan says the epidemic has improved. For the recently discussed new crown vaccine, he said cautiously that there were not all the data. “We are ready to start vaccination as soon as the vaccine is effective and safe.
