| 1 | Association Between COVID-19 Vaccination Coverage and Case Fatality Ratio:a Comparative Study—Hong Kong SAR,China and Singapore,December 2021–March 2022显示文摘Summary What is already known about this topic?Hong Kong Special Administrative Region(SAR),China and Singapore are both facing considerable Omicron variant epidemic.However,the overwhelmed medical system and high case fatality ratio(CFR)just occurred in Hong Kong SAR,China but not in Singapore.What is added by this report?The low vaccination coverage in Hong Kong SAR,China,especially among the older adults,is shown to be a primary reason of its recent high CFR.What are the implications for public health practice?Facing the potential epidemic risk,non-vaccinated,non-fully-vaccinated,and non-booster-vaccinated people in China,especially the elderly,should get any type of accessible vaccine,which could save lives when the infection unfortunately befalls. | Guanhao He Sui Zhu Di Fu Jianpeng Xiao Jianguo Zhao Ziqiang Lin Tao Liu Xiaofeng Liang Wenjun Ma | 2022 | China CDC weekly2022，4，30： | 2 |
| 2 | Long-Term Trend Analysis of Major Human Helminth Infections — Guangdong Province, China, 1988–2021显示文摘Introduction:Although helminth infections threaten millions of people worldwide,the spatiotemporal characteristics remain unclear across China.This study systematically describes the spatiotemporal changes of major human helminth infections and their epidemiological characteristics from 1988 to 2021 in Guangdong Province,China.Methods:The survey data in Guangdong Province were primarily obtained from 3 national surveys implemented during 1988–1992,2001–2004,and 2014–2016,respectively,and from the China Information System for Disease Control and Prevention during 2019–2021.A modified Kato-Katz technique was used to detect parasite eggs in collected fecal samples.Results:The overall standardized infection rates(SIRs)of any soil-transmitted helminths(STH)and Clonorchis sinensis decreased from 65.27%during 1988–1992 to 4.23%during 2019–2021.In particular,the SIRs of STH had even more of a decrease,from 64.41%during 1988–1992 to 0.31%during 2019–2021.The SIRs of Clonorchis sinensis in the 4 surveys were 2.40%,12.17%,5.20%,and 3.93%,respectively.This study observed different permutations of gender,age,occupation,and education level on the SIRs of helminths.Conclusions:The infection rate of STH has substantially decreased.However,the infection rate of Clonorchis sinensis has had fewer changes,and it has become the dominant helminth. | Yueyi Fang Jiong Wang Guanhao He Qiming Zhang Jianpeng Xiao Jianxiong Hu Zuhua Rong Lihua Yin Fangfang Zeng Pan Yang Xiaomei Dong Dan Liu Xiaofeng Liang Zhuohui Deng Tao Liu Wenjun Ma | 2022 | China CDC weekly2022，4，41： | 1 |
| 3 | Effectiveness of COVID-19 Vaccination Against SARS-CoV-2 Omicron Variant Infection and Symptoms—China,December 2022–February 2023显示文摘Summary What is already known about this topic?A considerable percentage of the population has received both primary and booster vaccinations,which could potentially provide protection against severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)Omicron infections and related symptoms.What is added by this report?The self-reported infection rate,as determined from an online survey,reached its peak(15.5%)between December 19 and 21,2022,with an estimated 82.4%of individuals in China being infected as of February 7,2023.During the epidemic,the effectiveness of booster vaccinations against SARS-CoV-2 Omicron infection was found to be 49.0%within three months of vaccination and 37.9%between 3 and 6 months following vaccination.Furthermore,the vaccine effectiveness of the booster vaccination in relation to symptom prevention varied from 48.7%to 83.2%within three months and from 25.9%to 69.0%between 3 and 6 months post-booster vaccination. | Di Fu Guanhao He Huanlong Li Haomin Tan Xiaohui Ji Ziqiang Lin Jianxiong Hu Tao Liu Jianpeng Xiao Xiaofeng Liang Wenjun Ma | 2023 | China CDC weekly2023，5，17： | 0 |
| 4 | When and How to Adjust Non-Pharmacological Interventions Concurrent with Booster Vaccinations Against COVID-19—Guangdong,China,2022显示文摘Introduction:With the large-scale roll-out of the coronavirus disease 2019(COVID-19)booster vaccination effort(a vaccine dose given 6 months after completing primary vaccination)in China,we explore when and how China could lift non-pharmacological interventions(NPIs)against COVID-19 in 2022.Methods:Using a modified susceptible-infectiousrecovered(SIR)mathematical model,we projected the COVID-19 epidemic situation and required medical resources in Guangdong Province,China.Results:If the number of people entering from overseas recovers to 20%of the number in 2019,the epidemic in 2022 could be controlled at a low level by a containment(215 local cases)or suppression strategy(1,397 local cases).A mitigation strategy would lead to 21,722 local cases.A coexistence strategy would lead to a large epidemic with 6,850,083 local cases that would overwhelm Guangdong’s medical system.With 50%or 100%recovery of the 2019 level of travelers from overseas,the epidemic could also be controlled with containment or suppression,but enormous resources,including more hotel rooms for border quarantine,will be required.However,coexistence would lead to an uncontrollable epidemic with 12,922,032 local cases.Discussion:With booster vaccinations,the number of travelers from overseas could increase slightly in 2022,but a suppression strategy would need to be maintained to ensure a controllable epidemic. | Guanhao He Fangfang Zeng Jianpeng Xiao Jianguo Zhao Tao Liu Jianxiong Hu Sicong Zhang Ziqiang Lin Huaiping Zhu Dan Liu Min Kang Haojie Zhong Yan Li Limei Sun Yuwei Yang Zhixing Li Zuhua Rong Weilin Zeng Xing Li Zhihua Zhu Xiaofeng Liang Wenjun Ma | 2022 | China CDC weekly2022，4，10： | 0 |
| 5 | 中国环境温度对不同伤害死亡的影响(摘译)显示文摘伤害是一个严重的公共卫生问题,据世界卫生组织估计,全球每年有440万人死于伤害,接近总死亡人数的8.0%。在中国,伤害防控也是重要的公共卫生问题之一。在经济快速发展的背景下,虽然中国在过去三十年的伤害死亡率和伤残调整生命年(disability adjusted life years,DALYs)均呈下降趋势,但伤害仍是第五大死亡原因,以2017年为例,伤害占全国死亡人数的7.0%、占全死因DALYs的10.0%。 | 胡建雄 黄兴凤(摘译) 马文军(审校) HE Guanhao MENG Ruilin | 2023 | 伤害医学(电子版)2023，12，4： | 0 |
| 6 | Excess mortality, rather than case fatality rate, is a superior indicator to assess the impact of COVID-19 pandemic显示文摘Since the end of 2021,the world has been grappling with a series of coronavirus 2019(COVID-19)outbreaks caused by the highly transmissible Omicron variant.Though the Omicron variant has a fatality rate that is lower than other variants and high vaccine coverage,more countries have lifted their non-pharmaceutical interventions(NPIs)and tried to combine natural infection and vaccine immunity to achieve herd immunity so as to coexist with the virus. | Guanhao He Jianpeng Xiao Ziqiang Lin Wenjun Ma | 2022 | The Innovation2022，3，5： | 0 |
