新加坡专家：少数猴痘患者无症状 但传播率低_我的网站

A |     FORT LAUDERDALE, Fla. -- Lionel Messi is evidently going back to China, after Inter Miami took advantage of not making the Major League Soccer playoffs by signing a deal to play two exhibitions there next month.The team said it would play a pair of friendlies against Chinese Super League teams, first in Qingdao, China against Qingdao Hainiu on Nov. 5 and then against Chengdu Rongcheng in Chengdu, China on Nov. 8. Those two stadiums can both hold between 50,000 and 60,000 fans.Those dates coincide with the first round of the MLS playoffs. Inter Miami was eliminated from playoff contention earlier this month.Inter Miami's announcement of the deal did not specifically mention Messi or any other player, though it would be surprising if Chinese officials agreed to the games without some sort of guarantee that the seven-time Ballon d'Or winner and the team's other best-known standouts — Sergio Busquets and Jordi Alba among them — would be making the trip if physically able.“This will be a great opportunity to continue building on our 2023 campaign, in which we achieved our first-ever trophy,” Inter Miami sporting director and chief soccer officer Chris Henderson said in a release distributed by the team. "We will take this as an opportunity to begin our preparations for 2024, as we look to build on last season and find more success moving forward.”If Messi — who led Argentina to the World Cup title last year — plays, it would be at least the eighth time he has traveled to China for exhibitions for club or country since 2005. Ticket for all previous Messi appearances have sold at a wild pace in China, a nation that has a massive soccer following even without much in the way of global success by the men's national team. China's women made the World Cup final in 1999, falling to the U.S. in a penalty-kick shootout to decide the title at the Rose Bowl in California.Messi has played in China as recently as this past June, shortly after he stunned much of the soccer world by announcing that he was signing a 2 1/2-year contract worth around $150 million to come to MLS and play for Inter Miami. He scored barely one minute into a match for Argentina against Australia in Beijing on June 15, and later was surprised by fan — one wearing a Messi jersey — somehow getting onto the field to ask for a hug.Messi also won Olympic gold in China, helping Argentina win the title at the Beijing Games in 2008. He and Inter Miami co-owner David Beckham have enormous followings in Asia, along with several endorsement deals in the region.This is the first international tour for Inter Miami, which is about to end its fourth MLS season. The team won the Leagues Cup this season, doing so shortly after Messi began playing for Inter Miami in July.The team didn't reveal television or ticket information. The lowest-priced seats for Messi's appearance at Beijing in June were listed at $80 and the highest-priced were around $670 at face value; if the price points for that match are similar to what's set on this tour, the two matches could generate well over $20 million in ticket revenue alone.That suggests this trip could be another major financial win for Inter Miami. MLS officials said Messi's jersey has been the league's top seller in 2023 — even though it wasn't on sale until July — and the team has told its season ticket holders that it plans to increase prices dramatically for the 2024 season.“We’re very excited to continue to expand our club's global reach, bringing our team to play in front of incredible fans across the globe," Inter Miami chief business officer Xavier Asensi said in remarks distributed by the club. "This is a special opportunity to share the passion as we reach new audiences and put ourselves on display in new places, and we’re looking forward to beginning this adventure.”Inter Miami finishes its MLS season this week with matches against Charlotte on Wednesday and Saturday. Messi is currently with Argentina's national team for World Cup qualifying and — given that nothing is at stake — it would seem unlikely that he'll appear in either of the final two MLS matches of the season for his club.The team hasn't publicly revealed plans for any other international tours for 2024, but others are expected given Messi's enormous global popularity.___AP soccer: https://apnews.com/hub/soccer。    （新加坡讯）感染猴痘未必一定会出现皮疹和发烧等常见症状，新加坡传染病专家指出，已有研究发现极少数感染者呈无症状状态，并有国家已斥资上百万元对猴痘的无症状传播进行大规模研究。

B | 杀伤力较大的中非株猴痘病毒（CladeI）在刚果民主共和国、中非共和国和卢旺达等非洲国家迅速传播，并扩散至非洲以外的国家，包括菲律宾和泰国都出现病例。新国已加紧边境防范，在机场和港口设立体温监测站，筛查从有猴痘传播风险国家入境的人士。人感染猴痘的初期症状包括发烧、头痛、肌肉酸痛、背痛和淋巴结肿大，之后可发展为面部和身体大范围皮疹。不过受访传染病专家说，猴痘存在无症状感染和传播的可能性，但出现的概率小。新加坡已加紧边境防范，在机场和港口设立体温监测站，筛查从有猴痘传播风险国家入境的人士。（档案照）《新明日报》报导，国际传染病学学会会长淡马亚教授（PaulTambyah）受访时指出，英国政府上个星期四（8月22日）发文告宣布，斥资100万英镑针对猴痘的无症状传播开展研究。

C | 根据文告，已有研究表明一些人感染猴痘后不会出现任何症状，但由于这些研究的规模较小，英国政府想通过大规模调查，了解这类无症状感染的普遍性。淡马亚说，感染后确实可能症状非常轻微，比如有报道称确诊者仅是直肠内出现单一溃疡，成为猴痘传染源。这类症状很难被发现，因此可能被归纳为“无症状”，而真正的无症状传播可能性很低。

D | 传染病专家梁浩楠医生说，据他所知虽然无症状感染病例还未被记录，但的确有可能出现。不过斐瑞医院传染病专科医生卢家燊认为，人们感染后出现症状所需时间不同，“无症状”可能是在记录当下没有症状，不排除过后就会出现症状。“就像水痘一样，感染猴痘没有‘痘’的情况很少。

猴痘不会社区接触传播非洲访客无需隔离

    新加坡国立大学杨潞龄医学院弗斯尔（DaleFisher）教授告诉《海峡时报》，猴痘不像冠病那样，会通过日常的社区接触传播。目前阶段不需要对从非洲疫情国家来新人士进行隔离，除非他们与疑似猴痘患者有过密切接触，或本身有高风险性行为。南洋理工大学李光前医学院巴纳比·扬（Barnaby Young）副教授说，鉴于猴痘的传播主要通过和确诊者长期且密切的接触，游客一般上可以免于被感染。

皮疹最明显时传染力最强

    淡马亚说，水痘和猴痘相比较下，前者在感染早期传染力最强，出疹前一两天就具传染性；而猴痘是在皮疹最明显时传染力最强。卢家燊也指出，猴痘只要一有症状就能传播，在生出皮疹时最具传染力。梁浩楠医生也说道，猴痘病毒主要还是通过亲密接触才会感染，但在特定情况下有机会通过飞沫传播。“这种情况（的传播）很难发生，除非在配偶或伴侣之间，需要他们面对面紧挨着脸，好像要亲吻那样才有可能（飞沫）传播。”猴痘痊愈后出疹的皮肤也能恢复如常吗？卢家燊说不一定，像水痘一样，有些人在皮疹消散后，会留下轻微的疤痕。
