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.
。本版摄影记者陈中秋昨天傍晚，今年第13号台风“白海豚”连续两次在浙江登陆。17点30分前后，“白海豚”先在浙江省台州玉环市坎门街道沿海登陆，登陆时中心附近最大风力有14级（42米/秒），中心最低气压为945百帕；18点40分前后，“白海豚”在浙江省温州乐清市翁垟街道沿海再次登陆，登陆时中心附近最大风力有13级（38米/秒），中心最低气压为950百帕。昨天，杭州市气象台升级为台风黄色预警信号，临安升级为台风红色预警信号，这也是自2012年以来杭州地区再次发布台风红色预警信号。台风登陆后，风雨影响还会继续，大家不要掉以轻心。今天我省大部分地区依然有大雨到暴雨，部分大暴雨。

C | 预计杭州今天白天阴有大到暴雨，夜里阴有中雨，最大东北风6~8级、阵风9~10级，白天最高气温29℃，早晨最低气温24℃。请大家做好台风防御工作，尽量少出门。台风“白海豚”两次登陆浙江今天全省大部有大雨、暴雨，部分大暴雨台风“白海豚”给浙江带来明显风雨影响，尤其是位于“危险半圆”（一般在台风前进方向的右侧，往往是最大风速出现的地方）内的地区，风雨势头最为猛烈。浙江省气象服务中心说，昨天14点至17点，嘉兴东部、杭州东部和西北部、绍兴北部和东部、宁波中南部、金华东部、台州、温州北部、丽水北部等地区出现大雨，部分暴雨，其中宁波南部、台州中东部、温州北部等地局部大暴雨，浙江沿海海面、沿海地区和高山区出现11~14级、局部15~17级阵风，内陆地区出现8~11级阵风，山区局部11~13级。登陆后，“白海豚”带来的风雨影响还在继续。预计今天东海海域部分仍有9~11级阵风。今天沿海海面风力12~14级，逐渐减弱至11~12级，内陆地区大部8~11级，山区和江河湖面局部11~13级。今天上午全省大部有大雨、暴雨，部分大暴雨，其中台州、宁波、温州北部、丽水东部、金华东部、绍兴东部等地局部有特大暴雨；今天下午到夜里浙西北和沿海地区部分大到暴雨，局地大暴雨。预计今天早晨，杭州阴有大到暴雨，东部、北部局部大暴雨，最大东北风平原地区8~10级，高山区和江湖水面10~12级，个别12级以上；今天白天阴有中雨，北部、西部山区局部暴雨，东南风5~7级，山区和江湖水面7~9级，个别10级。昨天下午，西湖边北山街一棵悬铃木发生倒伏，园林部门迅速处置，恢复道路畅通。

D | “白海豚”登陆地点复刻“巴威”未来三天10余省市将出现强降雨自7月27日生成以来，台风“白海豚”长途奔袭，其间经历多次眼壁置换，巅峰时期环流直径超1300公里，其生命史之长、移动路径之远，十分少见。台风“白海豚”与今年第9号台风“巴威”有一些相似之处：都经历了长距离移动，都曾达到超强台风级，而且环流范围较大。从登陆地点看，之前的台风“巴威”，也是先登陆玉环坎门，再登陆乐清。中国气象频道气象分析师信欣说，这两个台风都是超远距离奔袭，最后登陆点重合，确实难得一见。“白海豚”的环流更大，强度更强，登陆后的路径总体比“巴威”偏西，对华东、华北的影响会大于“巴威”。尤其是12日—15日，“白海豚”的残涡可能叠加冷空气，导致河南、山东、河北等地出现强降雨，因此后期北方地区也要高度关注。中央气象台首席预报员许映龙介绍，与今年第9号台风“巴威”相比，“白海豚”局部风力有可能更强，且降雨的强度更强、范围更广，局地单点降水具有极端性。
