| 1 | Evaluating the effectiveness of control measures in multiple regions during the early phase of the COVID-19 pandemic in 2020显示文摘The number of COVID-19 confirmed cases rapidly grew since the SARS-CoV-2 virus was identified in late 2019.Due to the high transmissibility of this virus,more countries are experiencing the repeated waves of the COVID-19 pandemic.However,with limited manufacturing and distribution of vaccines,control measures might still be the most critical measures to contain outbreaks worldwide.Therefore,evaluating the effectiveness of various control measures is necessary to inform policymakers and improve future preparedness.In addition,there is an ongoing need to enhance our understanding of the epidemiological parameters and the transmission patterns for a better response to the COVID-19 pandemic.This review focuses on how various models were applied to guide the COVID-19 response by estimating key epidemiologic parameters and evaluating the effectiveness of control measures.We also discuss the insights obtained from the prediction of COVID-19 trajectories under different control measures scenarios. | Zengmiao Wang Jason Whittington Hsiang-Yu Yuan Hui Miao Huaiyu Tian Nils Chr.Stenseth | 2021 | Biosafety and Health2021，3，5： | 0 |
| 2 | Optimization of Population-Level Testing,Contact Tracing,and Isolation in Emerging COVID-19 Outbreaks:a Mathematical Modeling Study—Tonghua City and Beijing Municipality,China,2021–2022显示文摘Introduction:The transmissibility of the severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)Omicron variant poses challenges for the existing measures containing the virus in China.In response,this study investigates the effectiveness of population-level testing(PLT)and contact tracing(CT)to help curb coronavirus disease 2019(COVID-19)resurgences in China.Methods:Two transmission dynamic models(i.e.with and without age structure)were developed to evaluate the effectiveness of PLT and CT.Extensive simulations were conducted to optimize PLT and CT strategies for COVID-19 control and surveillance.Results:Urban Omicron resurgences can be controlled by multiple rounds of PLT,supplemented by CT—as long as testing is frequent.This study also evaluated the time needed to detect COVID-19 cases for surveillance under different routine testing rates.The results show that there is a 90%probability of detecting COVID-19 cases within 3 days through daily testing.Otherwise,it takes around 7 days to detect COVID-19 cases at a 90%probability level if biweekly testing is used.Routine testing applied to the age group 21–60 for COVID-19 surveillance would achieve similar performance to that applied to all populations.Discussion:Our analysis evaluates potential PLT and CT strategies for COVID-19 control and surveillance. | Zengmiao Wang Ruixue Wang Peiyi Wu Bingying Li Yidan Li Yonghong Liu Xiaoli Wang Peng Yang Huaiyu Tian | 2023 | China CDC weekly2023，5，4： | 0 |
