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.
。这份沉甸甸的丰收来得不容易。在场的萧山区农技专家介绍，相较去年，今年早稻生长期阴雨天气偏多，光照、积温明显不足，制约水稻光合作用与养分积累，整体生长态势受限。杭州农技团队选择与天气“抢”产量。市区两级专家扎进田间地头，手把手指导农户精准施策、科学管护。以精细化田间管理对冲天气短板，稳稳守住了粮食产能底线——育秧阶段，攻关示范片创新采用大钵体毯状苗育秧技术，精细化培育壮秧，夯实高产基础。这套技术有效降低了插秧漏插率，助力秧苗移栽后快速返青、早生快发、有效分蘖，为稳产高产筑牢根基。施肥管护环节，田间全面应用侧深施肥技术，将肥料精准施于秧苗根部，大幅减少养分流失，有效提升肥料利用率，实现节肥、增效、稳产多重效果。

B | 同时，攻关示范片此次选用适配本地水土气候的优良品种“嘉育25”，该品种兼具优质、高产、高抗等优势，成为不利天气下逆势高产的核心支撑。这份“全省第一”的荣誉，是杭州扎实抓粮油生产增效的一个生动注脚。今年，杭州市本级计划安排“米袋子”资金1.7亿元，其中粮油适度规模经营资金5380万元，真金白银调动农民种粮积极性。全市还布下了150个以上各级绿色优质高产高效创建区块，以点带面推广良种、良法和高效模式。农技专家更是频繁奔走一线，开展指导服务300余次，解决生产实际问题80余个。同时，杭州还建起了粮食和蔬菜应急储备库，为农业生产系上“安全带”。粮食生产，一季接一季，一茬接一茬。下半年，杭州将重点抓好晚稻夏播和早稻夏管专业指导，确保全年粮食生产任务圆满完成。

C | 在蔬菜稳产保供上，将巩固提升现有基地，新建一批优质稳产基地，同时，持续抓好历史经典产业建设指导、现代种业管理和农业防灾减灾工作，让更多田块像这片示范片一样，在风雨中依然能交出沉甸甸的丰收答卷。
