Jianzhou Island Emergency Notice: All personnel have paused in and out!Shanghai tourists staying in the North Sea: The first travel is trapped, and the dishes have been stored for a week

Guangxi Beihai, a famous seaside tourist city, became the focus of public opinion due to sudden epidemics

From the first infected person on July 12, the first infected person was discovered until the 7th day of Beihai reported that more than 700 local infections were reported within 7 days.

Emergency Notice of Beihai Lianzhou Island Tourism Area: All personnel have paused in and out

What are the current situations staying in Beihai? Is there a guarantee for their accommodation?

Shanghai tourists who stay in Beihai: After 2 months of home, they trapped the dishes that had been trapped for a week

Ms. Liang told Volkswagen · Poster Journalists that she asked the homestay boss to borrow the kitchenware and was lucky to buy some dishes online. She was ready for a long time. Ms. Liang said that during the spring of this year, she had been at home for more than two months. She did not expect that she was stranded in the first time I went to the country.

"Now the epidemic in Haicheng District is relatively serious. My health code has become red, and there is no place to go even if I go out." Ms. Liang said with a bitter smile. After she arrived in Beihai, she had no time to have an epidemic. Now Every place requires scan code. Except for going out to do nucleic acids, she can't get in other places.

Ms. Liang arrived in Beihai City on July 9. She was stranded after the epidemic on the 12th. "I plan to do it. I was going to go to Beihai for a few days to go to Beihai to go to Guilin and Yangshuo for a few days, and then take a plane to Haikou. Now the entire travel plan has been disrupted." Ms. Liang complained.

The nearby takeaway almost stopped. In order to solve the problem of eating, Ms. Liang borrowed kitchen utensils such as an induction cooker from the hostel, and communicated with the boss to change a room with a refrigerator to prepare to cook by herself. On the 17th, she was very lucky to buy dishes before the online store was suspended. She stored tomatoes, eggplant, cabbage, potatoes, etc. in the refrigerator for a week.

"The price of the vegetables I bought online yesterday was almost the same as usual. When I went downstairs to get vegetables, there was a resident of the community asking me where I bought it because they couldn't buy it." Ms. Liang told Volkswagen.com. Most of the vegetable markets have been suspended, and she can buy vegetables on the mobile phone that only a few online shopping supermarkets can be bought.

Ms. Liang rented a homestay in a community not far from the seaside. Because she was not in the community's group, she could not receive information issued by the community as soon as possible. "The community property said that as long as the nucleic acid detection is always negative, the health code will turn green about a week, but I don't know what he said." Sub -nucleic acid, and made the psychological preparation of being trapped in the North Sea for half a month.

Ms. Liang, 27, is engaged in the financial industry in Shanghai. During the Shanghai epidemic in the spring of this year, she was home from March 31st to June 1st. When the situation was relieved, I finally dared to rest assured that I met the epidemic in Beihai for the first time. "It's relatively calm now, and she is accustomed to isolation." Ms. Liang mocked himself.

Ms. Liang worked online every day during the stay at home, but she did not know friends in Beihai and felt very lonely. She hoped that she could contact Shanghai female tourists who had the same experience to communicate the information. When she left, she could be a companion.

At present, the environment where the hostel is located is very good. You can see the sea in the room, which gives Ms. Liang a little comfort. "After the end of the Beihai City epidemic, go to Puzhou Island to play, then go to Guilin and Yangshuo to play," Ms. Liang said.

Tourists staying on the island of Dazhou: I once boarded the outlying island ship and drifted on the sea for 2 hours and then returned to the island

"According to my understanding, the passenger ships and cargo ships on the island of Puzhou have been suspended, and now they are mainly facing the problem of material lack." A Ms. Zhang, a tourist who claimed to be stranded on the Island of Beihai, told the Red Star journalist.

The sudden epidemic caused Ms. Zhang, who was on the island in June, was stranded on the island. "On the day of the issuance of the outlying islands policy on July 15, I did not grab the tickets, nor had no 48 -hour nucleic acid certificate, so I couldn't leave in time."

Public information shows that the island of Puzhou Island is located in the middle of the Beibu Gulf waters and is the largest island in Guangxi. Many scenic spots on the island attract many passengers every summer. To arrive at Laizhou Island, you need to board the ship at the Beihai International Passenger Pier to return to and from the island.

According to CCTV News, on July 14, the Dazhou Island Tourism Zone has suspended the reception of tourists to go to the island and suggested that the islanders and merchants are not necessary to leave the island. On July 17th, the New Crown Pneumonic Pneumonia Epidemic Prevention Headquarters in the Tourism Area of ​​Laizhou Island issued a notice to suspend all personnel entering and leaving the Tongzhou Island tourist area; restaurants and units can be suspended to provide takeaway services; Ships must strictly implement the system of going to the sea, enter and exit ports on time, and cannot contact other personnel during the time of going to sea. Non -Island fishing vessels and personnel on the operating ship cannot enter the port to go ashore.

Ms. Zhang told reporters the "dilemma" of her outlying islands. She said that the local staff on July 15 informed that they left the island as soon as possible, but on the 16th, many tourists still did not grab a ticket.

On July 17th, the local notice was issued, and Ms. Zhang received a notice from the last ship to the island's outlying islands and boarded the last ship of the outlying islands as required. "I didn't plan to leave the island so soon, but the notice said that only merchants and islanders could stay on the island, so I also got on the boat."

But this time, Ms. Zhang still failed to leave the island. "After drifting on the sea for about two hours, the ship returned to Laizhou Island, and no one notified us. Later, because of the policy update, tourists were not allowed to go to the island to go to the island. . "Ms. Zhang, who stayed on the island, told Red Star News that at present, she needs to pay for food and accommodation, and the catering on the island is closed, so the supplies are relatively lacking, and the price has also risen obviously. "The demand of a stranded passenger is that the supplies can be supplied normally, the epidemic prevention can be guaranteed, the outlying time can be notified in time, and we will also actively cooperate." Ms. Zhang said.

In this regard, Red Star reporters called the Kuizhou Island epidemic prevention and control hotline on July 18. The wiring staff said that it still cannot be outdoor and the island. The sealing date has not been determined. The epidemic prevention policy will be dynamically adjusted according to the epidemic situation.

Why does the North Sea epidemic rise? How can it spread so fast?

On the 18th, a press conference on the prevention and control of the Guangxi New Crown Pneumonia Epidemium was reported. At present, the situation in Beihai's epidemic situation is severe and complicated, and it is in a critical period in the epidemic.

According to reports, there are three main characteristics of Beihai's epidemic: First, the characteristics of local gathering and multi -point community communication are present. Haicheng and Yinhai District are high -incidence areas. The second is that most of the infected people are associated with the Jingui Market, suggesting that the Jingui Market is a major outbreak and diffusion point of this epidemic. Third, the epidemic spreads fast, and the propagation is hidden. This epidemic was caused by Omikon's mutant strain BA.2.3, and the number of infections exceeded 500 cases within 6 days after the outbreak.

Including the mutant strains discovered by Beihai, BA.2.3, in China, there are 10 types of Omircong mutant strains in China. Where do they come from?

Since July 6 this year, Xi'an has confirmed that China ’s first local cases infected with Omikon BA.5 mutant strains, and within two weeks of July 17, China has reported as many as 10 species in many places in China. Omikon subtype of mutation. The accelerated evolution of the new coronal virus has also aroused concerns from scientists.

On July 17th, Chengdu reported that the latest round of epidemic gene sequencing analysis, the infected person was infected with the Omikon subtype of BA.2.12.1, and the homologous sequence was not found in the domestic local epidemic database.

All mutant strains are overseas input

BA.2.12.1 was the first to discover in the United States earlier this year. It was a branch of BA.2 mutant strains, but the spread was 23%to 27%higher than BA.2. BA.2.12.1 once became a popular strain in the United States, but it was gradually replaced by BA.5. Currently in the United States, BA.5 has accounted for more than 65%of new cases.

In addition, in the latest round of epidemic in Lanzhou, Gansu, the BA.2.38 of the Omikon mutant strain was monitored. The mutant strain was also a branch of the BA.2 mutant strain and was recently popular in India. Within 30 days of July 2nd, BA.2.38 occupied about 30%of India's new cases.

Other Omir Rong mutant strains monitored in China also include BA.5.2.1 mutant strains reported by Shanghai, Tianjin and Qingdao; BA.2.3 mutant strains reported by Guangzhou, Foshan and Beihai; BA reported by Guangdong, Shanghai, and Linyi .2.2 mutant strains; BA.5.2 mutant strains reported by Xi'an; BA.5 mutant strains reported by Dalian and BA.2 and BA.4 reports reported by Tianjin; BA.5.1 mutant strains reported by Zhuhai.

It is worth noting that all the above Omikon subtypes are entered into our country for the popular strains abroad. For example, the BA.5.2.1 mutant strain monitored in Shanghai for the first time was discovered in Belgium for the first time in May this year and spread in many European countries; BA.2.3 mutant strains were also discovered for the first time in the United States.

"This means that we should still adhere to external defense input and the dynamic zero -zero policy of internal defense. When we find that input -input epidemic spread, we must extinguish it in time." A public health expert told the first financial reporter.

In accordance with the requirements of China's ninth edition of the new crown prevention and control plan, 7 -day centralized isolation medical observation of the entry -oriented personnel + 3 Heavenly House health monitoring.

In the week of July 17, China average reported 390 new crown cases every day, an increase of 340 cases the previous week. However, the source of virus infection has not been found in the epidemic survey in many places.

The more people infected, the greater the chance of mutation

According to the first financial reporter, in a round of Chinese epidemic in March this year, most people infected Omikon BA.2 mutant strains. In the past few months, Omikon has evolved more mutant strains, and the virus spreads faster. For example, the BA.4 and BA.5 mutant strains found in South Africa for the first time have about 13%to 15%of the communication advantages of BA.2, and they can also escape the immunity of BA.2.

Some virusists introduced that although the names of these mutant strains are different, they all belong to Omikon. From the perspective of the virus structure, the difference is not much. During the virus spread, about 2 amino acid positions appear about 2 a month per month. Point changes, similar characteristics, and immune response are similar.

Although from the current report of the real world report, whether it is BA.2.12.1, BA.2.38, or BA.5 mutant strains, it shows that they will not cause more serious diseases, but this does not mean that it is possible Relax and vigilance, because the ability to evade immune from these mutant strains can lead to a large number of re -infections, and because of their rapid transmission, new variations may also be accelerated. "Data show that from the perspective of virus infection cells, Omikon's pathogenic force has decreased, but the virus replication rate has increased, and the virus is constantly mutating and evolving, which may lead to the existing vaccine of the existing vaccine The decline in protection has brought us new challenges. "Xu Jianguo, an academician of the Chinese Academy of Engineering and the director of the National Key Laboratory of the Infectious Disease Prevention and Control Center of the China Disease Control and Control Center, told the First Financial Reporter.

Xu Jianguo believes that the more people infected, the greater the chance of virus mutation, which is an indisputable fact. "Virus variants are fast, and the antigenicity of some mutant plants may change." He said, "So we must find new methods and techniques, cut it, and should be highly wary of the development of the epidemic."

The greater the virus spread from BA.1 to BA.5, the more powerful the virus is?

BA.5 has more mutations than BA.1, but the size of the number and the infectious power of the virus cannot be completely divided, and further research must be confirmed. "From the perspective of existing evidence, the spread of BA.5 is the strongest. If it is measured with the basic reproduction of the infectious disease (R0) to measure the infectiousness, when people do not obtain immunity, the new crown ancestor strains that have been spread in the early stage The R0 value is about 3.3, the R0 value of the deerta mutation strain is about 5.1, the R0 value of Omikon BA.1 is about 9.5, the R0 value of Omikon BA.2 is about 13.3, and BA.4/5 The R0 value may reach 18.6. "Gao Xiaodong, a member of the National Health and Health Commission medical institution infection and control expert committee, and deputy director of the Infectious Management Department of Zhongshan Hospital affiliated to Fudan University, told reporters.

Dong Xiaoping, chief expert of the China Centers for Disease Control and Prevention, said in an interview with the media recently that compared with the previous mutant strains, the spread of BA.4 and BA.5 mutant strains has increased significantly. The specific performance includes: first, the incubation period is significantly shortened, that is, the infected person can be positive in a short period of time, and the ability to spread viruses more strongly; second, research in Japan, South Africa and other countries and regions show that there is no in the case of no. In the case of interference or few public health measures, its transmission coefficient R0 value has reached 18, which has a high speed of communication. In some European countries and the United States, the BA.5 mutant strain has replaced other Omikon mutant branches, becoming an advantageous strain.

Gao Xiaodong emphasized a key detail to reporters, that is, the R0 value of BA.4/5 may reach 18.6. The premise is "when people do not obtain immunity", "immunity" here can be understood as "immune capacity "Including not wearing masks, no protection, no social distance, no inoculation of new crown vaccines, etc. In other words, when people do not do any protection, the R0 value of BA.4/5 may reach 18.6. "At present, this situation is unlikely in our real life, because most people wear masks and pay attention to protection. This also reminds us to adhere to the importance and necessity of traditional protection and vaccination." Gao Xiaodong Say.
