伦敦,7月16日(新华社)——根据周五发布的官方数据,英国每天新增5万多例冠状病毒病例,这是自1月中旬以来的最高数字。


官方数据显示,在最近24小时内,中国又报告了51870例新冠肺炎病例,使中国的新冠肺炎病例总数达到53332371例。


该国还记录了49例与冠状病毒相关的死亡。目前,英国与冠状病毒相关的死亡总人数为128642人。这些数字只包括第一次阳性检测后28天内死亡的人。


英国政府已证实,英国的大部分COVID-19限制措施将于周一结束,这是英国解除封锁路线图的最后一步或第四步。但科学家警告说,在这个阶段取消所有限制可能会增加危险变异的可能性。


根据英国政府咨询机构紧急情况科学咨询小组(SAGE)的最新估计,英国的冠状病毒复制数(R)介于1.2至1.4之间,这意味着平均每10人感染会感染12至14人。


与此同时,新冠肺炎的增长率范围为4% - 7%,即每天新增病例数增加4% - 7%。


至于疫苗接种,伦敦帝国理工学院和Ipsos MORI公布了他们最新的抗体监测报告,报告显示,几乎100%的人在注射辉瑞和阿斯利康的第二剂疫苗14天后抗体检测呈阳性。


5月12日至25日期间,超过207,337名参与者在家中使用手指针刺测试自己,跟踪英格兰各地自然感染或接种疫苗后的COVID-19抗体。


该报告称,在接种两种疫苗中的任何一种后,抗体检测呈阳性的人的比例在第一次接种后的4至5周达到高峰,然后开始下降,之后在第二次接种后大幅上升。


该报告还说,研究结果强调,随着限制解除,每个人都需要接种两剂疫苗,以获得抵御这种疾病的最佳机会。


“这项大型研究的结果显示,疫苗接种计划对成人抗体阳性产生了实质性影响。然而,在某些群体和地区,疫苗的覆盖率参差不齐,不太可能接种疫苗。伦敦帝国理工学院(Imperial College London)公共卫生教授海伦·沃德(Helen Ward)说。


"令人关切的是,贫困地区的低收入者、一些少数民族群体和招待等一些面向公众的职业的人可能仍然相对不受未来传播的保护。我们需要继续并加强努力,为这些群体接种疫苗,并确保其他保护措施到位,”沃德教授说。


为了让生活恢复正常,英国、中国、俄罗斯、美国和欧盟等国一直在争分夺秒地推出新冠肺炎疫苗。

LONDON, July 16 (Xinhua) -- Britain has recorded more than 50,000 new daily coronavirus cases, the highest number since mid-January, according to official data released Friday.

The country reported another 51,870 coronavirus cases in the latest 24-hour period, bringing the total number of coronavirus cases in the country to 5,332,371, official figures showed.

The country also recorded another 49 coronavirus-related deaths. The total number of coronavirus-related deaths in Britain now stands at 128,642. These figures only include the deaths of people who died within 28 days of their first positive test.

The British government has confirmed that most COVID-19 restrictions in England will end on Monday as part of the final step or Step Four of England's roadmap out of the lockdown. But scientists have warned that lifting all restrictions at this stage could increase likelihood of dangerous variants.

England's coronavirus reproduction number, also known as the R number, stood between 1.2 and 1.4, meaning, on average, every 10 people infected will infect between 12 and 14 other people, according to the latest estimate by the Scientific Advisory Group for Emergencies (SAGE), a British government advisory body.

Meanwhile, the growth rate range of coronavirus is 4 percent to 7 percent, which means that the number of new infections is growing by between 4 percent and 7 percent every day.

As for vaccination, Imperial College London and Ipsos MORI have published their latest antibody surveillance report, which showed that almost 100 percent of people tested positive for antibodies 14 days after their second dose of the Pfizer and AstraZeneca vaccine.

Over 207,337 participants tested themselves at home using a finger prick test between May 12 and 25, tracking COVID-19 antibodies across England following either natural infection or vaccination.

Following one dose of either vaccine, the proportion of people testing positive for antibodies peaked at four to five weeks after first dose and then started to decline before rising substantially in those who had a second dose, according to the report.

The findings emphasize the need for everyone to get both doses of the vaccine to receive the best chance of protection against this disease as restrictions are lifted, the report also said.

"Results of this very large study show the substantial impact of the vaccination program on antibody positivity in adults. However, coverage of vaccines is uneven with people in some groups and areas less likely to have been vaccinated.," said Helen Ward, Professor of Public Health at Imperial College London.

"It is concerning that people on low incomes, in deprived areas, some minority ethnic groups and in some public facing occupations such as hospitality, may remain relatively unprotected from future spread. We need to continue and intensify efforts to reach these groups with vaccination, and to ensure other protective measures are in place," said Professor Ward.

To bring life back to normal, countries such as Britain, China, Russia, the United States as well as the European Union have been racing against time to roll out coronavirus vaccines.
