China reported 522,000 newly confirmed COVID-19 cases in July, including 487 severe cases and one related death with cases showing a fluctuating upward trend, China's national disease control authority said.
The current uptick in infections represents another regular cyclical wave, with its severity comparable to surges seen in the past two years. The upward growth curve has slowed markedly, and the country is now on the plateau phase of this epidemic peak, said the Chinese Center for Disease Control and Prevention (Chinese CDC) on Thursday.
All tested infection samples were confirmed to be the Omicron variant, with the NB.1.8.1 strain and its sublineages accounting for the majority of circulating cases, the Chinese CDC said.
A Beijing-based respiratory disease specialist told the Global Times that waning population immunity, continued virus mutations that weaken existing antibody protection, and increased summer travel have contributed to the recent modest rise in infections. However, there is no evidence that the virus has become more pathogenic. Nationwide infections appear to be nearing their peak and case numbers may begin falling in late August.

According to sentinel hospital surveillance data, from June 29-July 5 to July 27-August 2, the proportion of influenza-like illness among all outpatient and emergency visits at China's 1,041 COVID-19 and influenza sentinel hospitals edged up with slight fluctuations, standing at 4.3 percent, 4.4 percent, 4.5 percent, 4.4 percent and 4.5 percent, respectively.
During the same period, the COVID-19 positivity rate among patients with influenza-like illness in outpatient and emergency departments rose for consecutive weeks.
Several factors drove the fluctuating rise in COVID-19 cases in July. Population immunity has waned, as more than six months have passed since the last major wave of infections for most people, while continued SARS-CoV-2 mutations have reduced the protection provided by existing antibodies, Li Tongzeng, a respiratory disease medic from Beijing You An Hospital to the Capital Medical University, told the Global Times on Friday.
These factors, combined with increased travel and population mobility during the summer vacation, contributed to the recent small-scale surge. Based on patterns observed in recent years, COVID-19 infections tend to rise every six to eight months as population immunity declines, said Li.
The expert noted that while the virus continues to mutate, there is no evidence that it has become more pathogenic. Clinical data show that most patients develop only mild symptoms, with very few progressing to pneumonia or requiring hospitalization.
The Chinese CDC noted on Thursday that since COVID-19 was reclassified as a Category B infectious disease under Category B management, it has evolved into a prevalent, recurring respiratory infectious disease in China, with one to two epidemic fluctuations occurring nationwide each year.
Li also noted that residual immunity from previous infections also helps reduce disease severity, with most reinfections presenting as mild upper respiratory symptoms that resolve within about a week. The single COVID-related death reported nationwide in July further indicates that the current fatality rate remains very low.
Judging from historical epidemic patterns and current case growth trajectories, national infection figures may begin to decline in late August. Nationwide case numbers are now nearly at their peak, with declines already observed in some regions, said Li.
The Chinese CDC also said on Thursday that surveillance had not detected any variants posing major public health risks, nor had the current wave caused notable disruptions to the healthcare system.
The public is advised to take appropriate protective measures, including wearing masks when necessary, maintaining good personal hygiene, adopting healthy lifestyles and getting vaccinated as recommended.

如今的NBA，比拼的不只是球星成色和数量、教练水平、球队财力，更是管理层对于薪资、选秀、交易和未来规划的综合运营能力。文|KK又逢世界杯年，勒布朗·詹姆斯决定将天赋带到费城76人。詹姆斯、恩比德、杰伦·布朗、马克西、埃奇库姆的组合，令无数球迷更加憧憬詹姆斯的第24个赛季。

B | 在备受关注的“决定5”之外，还有另一个让人震惊的事实是，詹姆斯与76人签署的，仅仅是一份为期两年、年均薪400万美元的老将底薪合同。为了争夺第五个冠军，詹姆斯甘愿降薪4875万美元，降幅超过92%，创下NBA历史最大降薪纪录。图源：费城76人社媒按上赛季常规赛21+6+7、季后赛23+7+7的数据来看，400万的詹姆斯无异于白菜价。但76人也并非不想给詹姆斯更高的薪水，而是给不起。不仅是76人，骑士和热火两个詹姆斯的热门下家，也都因为薪资空间受限，无法为詹姆斯提供超过千万的年薪。自2023年NBA联盟落地史上最严薪资协议后，NBA球队的运营逻辑发生了不小的变化：球队的运营操作容错率在降低，现在不仅要比谁更会花钱，更要比谁更会省钱。无论是组建多巨头的超级球队还是通过连续摆烂以囤积高顺位新秀，亦或是培养自家的超级巨星，这些主流的建队模式，现在似乎都无法走得长远。过去8年，8支不同的球队拿下了NBA总冠军，在这背后是多种截然不同的球队运营模式。如今的NBA，比拼的不只是球星成色和数量、教练水平、球队财力，更是管理层对于薪资、选秀、交易和未来规划的综合运营能力。

C | 联盟正在进入一个真正意义上的“球队运营时代”。梭哈巨星过去20年，NBA联盟最风靡的建队模式，无疑就是组建多巨头的超级战舰。从绿军三巨头到热火三巨头，再到勇士四巨头、篮网三巨头……“ALL IN”模式一次次证明，只要你聚集了多位超级球星，便能成为夺冠的热门，并吸引前所未有的关注。

D | 巨星带来巨大的利益，但也需要球队付出巨大的代价，最直观的就是需要缴纳巨额奢侈税。

E | 此外还有部分球队，付出了大量年轻球员或选秀权，透支未来只为换来能够改变比赛、冲击冠军的超级球星。

F | 勇士四巨头图源：NBA但2023年最严劳资协议落地后，这种模式正在逐渐失去竞争力。最主要的原因，即是这版劳资协议引入了被誉为“王朝终结者”的第二土豪线。在过去，即使球队需要缴纳高额奢侈税，也依旧还可以利用中产特例签人或者从买断市场补充即战力。但如今一旦跨越第二土豪线，这些操作权限都将受到极大限制：不可以使用中产特例签约球员，也不可以签约被买断后流入自由市场的球员。此外，其未来第七年的首轮选秀权还将被冻结，不可交易。如果连续三年中有两年超过第二土豪线，这个首轮选秀权将自动降至首轮末。2026-27赛季NBA薪资标准图源：网络在诸多的限制下，继续“靠砸钱解决问题”已经越来越难。因此，人们开始看到越来越多的“多巨头球队”或强队被迫拆队，例如双探花坐镇的凯尔特人，约基奇、穆雷领衔的掘金，杜兰特、布克、比尔带领的太阳。乃至吃到巨大新秀红利的雷霆，在夺冠一年后也不得不通过送走球员来缓解薪资压力。许多球队的遭遇都表明，打造超级球队，最重要的不是得到超级巨星，而是在得到超级巨星之后，还有能力围绕他们打造一支完整、均衡且具有持续竞争力的球队。冠军不是仅靠五个人就能赢下的。一个能拉开空间的射手、一位可靠的护框中锋、一位靠谱的外线防守尖兵……这些都是巨星之外的重要争冠拼图。但当球队的大部分薪资已经用来梭哈巨星，球队也就很难再有充足的空间去签下优质的“拼图型球员”。曾经风靡联盟的“ALL IN巨星”模式，已然从一条冠军捷径，变成一场风险越来越高的豪赌。“自研”巨星既然通过外部交易与自由市场 “梭哈”巨星的道路越走越窄，许多球队便将目光转向了内部，试图通过选秀和精心培育来打造属于球队自己的超级巨星。放眼当今联盟，这种建队模式不乏成功的先例与范本。过去几年，东契奇、爱德华兹、坎宁安、文班亚马等年轻球员，都在进入联盟后便迅速成长为球队核心乃至明星球员、联盟门面。文班亚马更是在进入联盟的第三年，就带领马刺杀进总决赛。这些球员不仅直接改变了球队战绩，更带来了巨大商业价值。对于中小市场球队而言，这种价值甚至远远超过竞技层面。

G | 图源：圣安东尼奥马刺社媒纽约、洛杉矶拥有天然的市场吸引力，而俄克拉荷马城、明尼阿波利斯、底特律等城市，则更需要属于自己的超级球星。一位本土培养出来的球星，可以成为整座城市的体育名片，带动门票销售、赞助合作、周边商品以及媒体关注，让球队拥有稳定且持续增长的商业价值。更重要的是，新秀合同还意味着巨大的“薪资红利”。按照联盟现行制度，一名高顺位新秀将在进入联盟后的数年里执行固定工资合同。如果他能够迅速成长为全明星甚至联盟门面，那么球队就能够用远低于市场价值的薪资，获得顶级球员的竞技贡献。

H | 而这几年，也正是一支球队补强阵容、冲击冠军的最佳窗口期。然而，新秀合同终究只是“红利”，并不是终点。当这些超新星的新秀合同到期，迎接他们的大概率是顶薪续约。

I | 而一份动辄数亿美元的合同，对球队薪资结构的影响是巨大的。文班亚马5年顶薪续约马刺图源：圣安东尼奥马刺社媒与此同时，超级球星对于球队竞争力的要求也会越来越高。球队必须以其为核心配置更好的阵容，以满足其争冠需求，最终走上“超级球队”的建队模式。也就是说，自己培养超级巨星，并没有彻底解决球队运营难题，只是为球队争取了几年更加宽松的发展时间。但对于小球市的球队来说，已经弥足珍贵。就算最后不得不放走亲自培养的巨星，获得的回报也已足够。摆烂经济学对于没有培养出自己的巨星又不愿砸钱的球队来说，就只能“相信过程”了：通过连续摆烂囤积高顺位新秀。如果球队的选秀眼光足够毒辣，那么多位高水平新秀及其新秀红利，将成为球队冲击总冠军的重要基础。例如向来选秀眼光到位的雷霆，近年来就通过此前在保罗·乔治交易中得到的多枚高顺位签，选中杰威、霍姆格伦等多位高水平新秀。利用新秀红利下的巨额薪资空间，雷霆交易来卡鲁索、哈腾等重要拼图。最终，在亚历山大的带领下，这群青年军杀出重围，捧起了奥布莱恩杯。图源：俄克拉荷马雷霆社媒但并非所有新秀都是高水平，也不是所有球队都有雷霆这般的选秀眼光。早年身为黄蜂队老板的迈克尔·乔丹，就因为选秀眼光太低，间接导致了球队陷入“摆烂-选秀-新秀水平不足-摆烂”的恶性循环。

J | 此外，摆烂模式在以前行得通有一个重要前提——高顺位签的确定性。在旧规则下，战绩最差的球队有25%的概率获得状元签，前三顺位的概率接近64%，摆烂的回报可谓相当稳定且可观。但近年来，NBA联盟正在不断收紧反摆烂政策。2026年出台的反摆烂新规更是被称为“史上最严”：战绩倒数前三的球队获得状元签的概率统一降至仅5.4%（低于中游乐透队）。并且新规还明确同一支球队不能连续两年获得状元签、不能连续三年进入选秀前五顺位。同时，联盟还有权对“非竞争性阵容”即恶意摆烂进行罚款，最高可达千万美元级别，严重者甚至可能被没收未来选秀权。这一系列的组合拳，将于2027年正式落地。届时，刻意输球、连续摆烂的性价比将被彻底摧毁。

K | 2025-26赛季爵士、步行者因摆烂被NBA罚款图源：温网社媒未来，一支球队如果要通过摆烂来重建，不仅需要高顺位的选秀权，更需要有优秀的球探、独到的选秀眼光、科学的培养体系、成熟的发展规划以及合理的薪资管理。摆烂，将成为一门愈加高深的学问。

L | 综上所述，NBA正在变成一场关于资源配置的竞赛。球队总经理的重要性，已经丝毫不亚于场上的球星和场边的主帅。

M | 如果说选秀决定未来、巨星决定上限，那么球队总经理就是决定球队能否正常运转、往更好的方向发展的人。一次续约、交易或选秀，就可能会葬送球队的努力甚至未来。优秀的总经理，可以利用合同结构、薪资规划、选秀眼光和交易策略，在有限的资源条件下持续打造具有竞争力的阵容。在大合同满天飞的时代，在天赋与野心、金钱与规则的博弈中，从选秀、交易到薪资管理，联盟的运行逻辑正在发生变化。

N | 而这些变化，将在未来持续影响NBA的竞争格局。
