确诊病例通报中出现“时空交集”概念 如何理解?******

  10月21日0时至24时,西安新增3例本土确诊病例(普通型),这是除上海旅行团成员之外出现感染的西安本土病例,意味着原本就十分紧张的防控形势更加严峻。

  在陕西省卫健委发布的病例轨迹中,很多人注意到了一个新鲜词汇——时空交集。本土确诊病例尚某某及其丈夫李某某10月15日乘坐D2746次列车(与甘肃10月19日发布的确诊病例95有时空交集)到兰州游玩。

  所谓的时空交集该如何理解?疾控部门相关人士介绍说,这是公安及电信部门的专业术语,在疫情追踪中采用时空交集人群概念,可以最大可能的发现潜在风险人群,将更多的因为存在时空交集而可能产生感染机会的人群纳入到流调监测之中,对于及时发现阳性病例具有重要作用,当然也意味着流调工作量的成倍增长。

  据了解,时空交集与另一种说法时空伴随是相同概念,指14天内,与确诊患者在同时间和空间网格内(通常以800米*800米为检测范围),共同停留过10分钟。通俗地说,比如,确诊患者14天内到过福州,而你这14天的轨迹与他有过交集,无论是身体上擦肩而过,还是通讯信号上的漂移,都可能被认定为时空伴随。经系统检测出,你与确诊患者发生时空伴随,属于风险人群中的时空伴随者,健康码便会变黄码。时空伴随者的黄码怎么转绿码呢?按要求进行核酸检测,结果为阴性后健康码恢复正常。

  由于此次疫情防控中采用了时空交集概念,有市民尽管与确诊病例或者密接者无直接近距离接触,但也纳入了风险管理。10月22日,就有人收到了来自西安市疫情防控指挥部的短信。短信内容如下:【西安市疫情防控指挥部】温馨提示:您好,在新冠肺炎疫情传播排查中发现,您曾处于风险场所,请您主动做好安全防护,立即到就近核酸检测点做核酸检测。感谢您的理解与支持!据了解,对于这部分人群,需要及时进行核酸检测,核酸检测正常后,健康码就会回归绿色。

WHO special session seeking 'pandemic treaty' amid Omicron concerns******

A special session of the World Health Assembly (WHA) kicked off on Monday amid growing concerns over the latest Omicron coronavirus variant, where the participants aim to negotiate a new "pandemic treaty."

Legally binding pandemic treaty。

The WHA May session this year decided to set up a working group to consider the findings and recommendations of a number of panels and committees on global preparedness for and response to COVID-19 before starting their discussions on Monday on the potential new "legally binding agreement between nations."

"COVID-19 has exposed and exacerbated fundamental weaknesses in the global architecture for pandemic preparedness and response," said World Health Organization Director General Tedros Adhanom Ghebreyesus at the opening of the special session.。

"The best way we can address them is with a legally binding agreement between nations, an accord forged from the recognition that we have no future but a common future," he said.。

According to Tedros, the new "pandemic treaty" is expected to address COVID-19 as "a crisis of solidarity and sharing."

"The lack of sharing of PPE (personal protective equipment), tests, vaccines, technology, know-how, intellectual property and other tools hindered our collective ability to prevent infections and save lives," he said, noting the lack of a consistent and coherent global approach has resulted in "a splintered and disjointed response, breeding misunderstanding, misinformation and mistrust."

Get prepared for Omicron。

The WHA special session coincides with the emergence of the highly mutated Omicron virus variant, which was designated by the WHO as a "variant of concern" (VOC) just three days ago.。

Though the WHO has said it is not yet clear whether Omicron is more transmissible or causes more severe disease than the other known variants, including Delta, concerns over its impact on the efficacy of existing vaccines and treatments have been growing.。

A number of countries have already introduced entry bans on travelers from South Africa, where Omicron was first confirmed on November 9 and has been identified in multiple European countries, including Belgium, the Netherlands, the United Kingdom, Portugal, and Sweden.。

Sweden's Public Health Agency on Monday confirmed its first case of the Omicron variant, found when a traveler who last week returned to Sweden from South Africa was tested.。

Portugal's National Institute of Health Doctor Ricardo Jorge (INSA) on Monday confirmed 13 cases of the Omicron variant in Portugal among players and staff members of the football club Belenenses SAD.。

The INSA said that the samples were collected and analyzed on Sunday, and that one of the players who tested positive had recently returned to the country from South Africa.。

In Germany, the COVID-19 seven-day incidence rate climbed to a new all-time high of 452.4, up from 386.5 a week ago, the Robert Koch Institute for infectious diseases announced on Monday.。

German virologist Christian Drosten told the broadcaster ZDF on Sunday that he was "quite concerned at the moment. I am surprised to see so many mutations in the virus."

In Cyprus, new anti-coronavirus measures relating to young school children came into force on Monday, with most COVID-19 clusters currently being found in schools.。

In addition to banning direct arrival from the eight African countries most affected by the Omicron variant, all travelers coming from other destinations will also be tested for the coronavirus at airports, said Michalis Hadipantelas, Cyprus' health minister.。

Polish Health Minister Adam Niedzielski said on Monday that the country's government is set to announce new restrictions to cope with the new variant, including tightened flight rules on seven southern African nations.。

"Omicron demonstrates just why the world needs a new accord on pandemics: our current system disincentivizes countries from alerting others to threats that will inevitably land on their shores," said Tedros.。

German winter Olympic coaches expect strong team China******

By Oliver Trust

BERLIN, Oct. 29 (Xinhua) -- German bobsleigh and skeleton athletes expect a strong team China competing at the Beijing 2022 Winter Olympics.

"We have to include Chinese athletes to the ones competing for medals at the Olympics. They are fast starters and have gained experience," said German skeleton head coach Christian Baude.

Baude and his team this week returned from test runs held on the new Olympic track in Yanqing, a northern suburb of Beijing.

The German coach said China's skeleton athletes "are fast starters."

German bobsleigh coach Rene Spies said this year's European Cup events taking place in advance of the Beijing Olympics will function as preparation events for athletes.

"We are eager to see what Chinese drivers are capable of. Fact is, we don't underestimate their skills. It's all about reaching the best level when we start in China," Spies added.

Spies said the German bob team is one of the favourites due to the latest results, but "the favourite role isn't in my mind at all. We know we face strong competitors and have to perform on the highest level."

To meet expectations the German Olympic association has initiated several innovations regarding equipment and training methods.

While bobsleigh drivers benefit from a newly created bob simulator, advanced spike plates for their shoes used in competition rely on a database performance analysis provided by a new measure sledge.

The association is counting on close cooperation with the science department of its sponsor, car manufacturer BMW. Due to limited tests caused by the COVID-19 pandemic, German officials looked for new solutions.

The spike plates, printed in a 3D process, are made of titanium and Inconel, material normally used in rocket science.

To discover the secrets of the new track, bob drivers count on a simulator similar to the one used by car-race drivers.

Olympic bob Champion Francesco Friedrich made 20 runs in the simulator before attending tests on the new Olympic track in Yanqing.

The simulator tests made things easier for training in China, as the new track delivers so far unknown challenges. "We knew from the start about the track's curves. It's a great help when you have to compete on a track without many training sessions," the bob pilot said.

Friedrich and colleagues will use experience made in the test runs in Yanqing to update the simulator.

Three times Olympic Champion Felix Loch called the measure sledge a great help "as it makes us find the perfect line down the track."

Loch and compatriots have been working on the project for over two years.

Association director Alexander Resch announced to use the simulator mainly in talent training and for the Olympic athletes.

"This new digital level gives us valuable support to prepare for competition and allows youngsters to get a deeper idea about the requirements of the sport," the official added. Enditem
