After Suihua, another recurrent case of COVID-19 was found in Yantai. Will this situation pose a threat to people?

Since the outbreak of new coronary disease, China has cured thousands of confirmed patients from beginning to end. Some patients are not easy to get sick again after producing antibodies, and some patients have the probability of recovery after being cured. For example, 1 recovered workers were recently found in Yantai, Shandong Province. At this stage, patients have been protected and tested, and all close contacts have taken control measures. So, is COVID-19 recovering from infectious diseases?

After Suihua in Heilongjiang, another case of COVID-19 recurrence was found in Yantai, Shandong. However, the Yantai Municipal Health and Health Commission also reminded in the notification on April 26 that there were no reinfection cases after the confirmed cases in China were cured.

1 cured case found in Yantai, Shandong Province. According to the circular issued by Yantai Municipal Health and Wellness Commission, the recovered cases discovered on 25th were students studying in the United States in Zhifu District of Yantai. Arrived in Shanghai on February 25th for protection and diagnosis. After the cure, the dna test of this case was negative. However, on April 25th, 20 days after his recovery, the worker was found to be nucleotide positive. At this stage, all the close contacts of this case have taken control measures, and the dna test results are negative.

At this stage, there is no case of reinfection after the confirmed case is cured in China. Please don't worry. In addition, remind people to do a good job in safety protection and maintain a healthy lifestyle, such as wearing a mask, washing hands frequently for disinfection and natural ventilation frequently.

Prior to this, on April 24, Wangkui County, Suihua City, Heilongjiang Province, found a relapse patient Yang when screening cured cases. At the beginning of this year, during the last wave of pneumonia in Wangkui County, the case was diagnosed as COVID-19. After the cure, dna tests were negative on March 29th and April 13. On April 24th, it was found that it was positive again, but there was no clinical manifestation. blood night analysis and imaging diagnosis remained unchanged.

Since the global epidemic occurred for more than a year, cases in which Yang recovered after the patient was cured in the hospital have been reported frequently. Why will it continue to recover after being cured? Will it be contagious after regaining yang?

Is Fuyang, COVID-19 contagious? Academician Zhong Nanshan, an academician of Chinese Academy of Sciences and an authoritative expert on respiratory diseases, gave a detailed introduction in the front. To put it bluntly, "Fuyang" should be mostly a wonderful fragment of nucleotide rather than a virus infecting itself. He feels that no matter whether the patient has an attack or not, if the patient causes a strong antigen, it is generally not easy to feel again. It is necessary to deeply analyze whether patients with recurrent Yang Can will infect others. Generally speaking, nucleotide highlighting is not contagious. Previously, some experts and scholars have molded the throat swab and necessary substances of "Fuyang" patients, but they have not molded the virus infection.

Zhang Wenhong, head of infection department of Huashan Hospital affiliated to Fudan University, also introduced in detail that Fuyang has a complex scientific research system, but Fuyang has no obvious clinical manifestations, and it is not easy to cause large-scale outbreaks in epidemiological history.

Several cases with positive recurrence have been found in China before. Professor Wu Zunyou, a clinical epidemiologist from China CDC126 October, said that, on the whole, the proportion of COVID-19 patients who showed nucleotide positivity again during the follow-up was not high, about below 5%. Limited scientific research reminds us that the recurrence of positive cases is not contagious, and no cases leading to transmission have been observed at this stage.

China CDC emphasizes that the vaccination rate in most countries and regions in the world is still low at this stage, and it is not easy to produce immune barriers in a short time. During the 20021May Day holiday, there is a high probability that the overseas pneumonia epidemic situation will be highly elastic and epidemic, and the risk of typing the pneumonia epidemic situation in China is still very high.

Improve self-protection ability. China CDC reminded that it is necessary to improve self-protection during the festival, adhere to the "three-piece epidemic prevention" and keep in mind the "five requirements for safety protection". Adhere to wearing a mask, social distance, cleanliness; Remember to wear a protective mask, keep a social distance, cover your dry cough and sneeze, wash your hands frequently and try to open the window. In addition, it is necessary to minimize thematic activities in places where people gather, indoor space is closed and natural ventilation is weak.

During the trip, when traveling by plane, train, vehicle, freighter and other means of transportation, you should abide by discipline and the Regulations on the Administration of Flight Attendants and Staff, wear masks throughout the journey, do a good job in hand hygiene, and keep your certificates properly for easy inspection. If there are symptoms such as headache, drowsiness, decreased or missing taste buds, dry cough and burning sensation during the whole journey, do a good job in preventing others from feeling, and immediately go to the designated medical institution for medical treatment on the principle of proximity, and cancel or interrupt the tour.

China CDC also clearly pointed out that the return trip should be observed for 14 days. In case of abnormal diseases, you should do a good job to prevent others from feeling, see a doctor immediately and take the initiative to inform the doctor of your travel history.

In addition, vaccination should be carried out according to the distribution of vaccines during holidays, especially the second dose should be carried out as soon as possible within 3 weeks or more to 8 weeks after the first dose of vaccine, so as not to endanger the second dose of vaccine due to tourism.
