| 1 | Cold-chain food contamination as the possible origin of COVID-19 resurgence in Beijing显示文摘COVID-19,caused by SARS-CoV-2[1,2],has been contained in China through stringent non-pharmaceutical interventions.Border control and quarantine have effectively prevented the virus from being spread by infected travellers,but the risk of resurgence caused by other routes of introduction and transmission remains unclear,and current strategies to prevent resurgence could be flawed.Since July,SARS-CoV-2 RNA contaminations in frozen food imported from countries with ongoing epidemics have been reported in nine provinces in China[3,4].However,there is no robust evidence of COVID-19 outbreaks initiated by environmentto-human transmission.Here we add to evidence of such transmission by investigating the recent COVID-19 resurgence in Beijing. | Xinghuo Pang Lili Ren Shuangsheng Wu Wentai Ma Jian Yang Lin Di Jie Li Yan Xiao Lu Kang Shichang Du Jing Du Jing Wang Gang Li Shuguang Zhai Lijuan Chen Wenxiong Zhou Shengjie Lai Lei Gao Yang Pan Quanyi Wang Mingkun Li Jianbin Wang Yanyi Huang Jianwei Wang COVID-19 Field Response Group COVID-19 Laboratory Testing Group | 2020 | National Science Review2020，7，12： | 51 |
| 2 | Cholera Caused by a New Clone of Serogroup O1 Vibrio cholerae-Beijing Municipality,China,June 2021显示文摘Several lineages have been identified in the population of serogroup O1 Vibrio cholerae(V.cholerae)(1-3).The strains,which were responsible for the ongoing seventh cholera pandemic,were in Lineage 2.Nearly all the V.cholerae strains in this lineage carried genes coding cholera toxin(ctxAB)(1-2).Lineage 3b consists of strains isolated from different continents and the vast majority of strains in this lineage lack the ctxAB genes. | Hanqiu Yan Bo Pang Xin Lu Zhiyong Gao Pan Lu Xin Zhang Mengyu Wang Lingyu Shen Wenxuan Zhao Jianhong Zhao Weili Liang Lei Jia Haijian Zhou Zhigang Cui Xiaoli Du Biao Kan Quanyi Wang | 2022 | China CDC weekly2022，4，2： | 3 |
| 3 | Extensively Drug-Resistant(XDR)Salmonella Typhi Outbreak by Waterborne Infection——Beijing Municipality,China,January-February 2022显示文摘Summary What is already known about this topic?Typhoid fever remains a major public health problem in developing countries.Waterborne typhoid fever affects an estimated 27 million people worldwide each year.Decades of indiscriminate antibiotic usage has driven the emergence and spread of multidrug-resistant(MDR)and even extensively drug-resistant(XDR)Salmonella Typhi(S.Typhi)strains. | Yu Wang Dan Lu Yingying Jin Huanxin Wang Bing Lyu Xin Zhang Ying Huang Gaolin Shu Baiwei Liu Changying Lin Hao Zhao Mingqiang Zhao Lingyu Shen Zhiyong Gao Daitao Zhang Quanyi Wang Mei Qu Lei Jia | 2022 | China CDC weekly2022，4，12： | 1 |

| 14 | Application of a ddRT-PCR to quantify seasonal influenza virus for viral isolation显示文摘Viral isolation in cell cultures has been regarded for decades as the“gold standard”for the laboratory diagnosis of influenza viral infections.Not all viral strains could be isolated from clinical samples.This study aimed to quantify the viral load in the samples before isolation to save working time and improve working efficiency.Four hundred samples from patients with influenza-like cases were confirmed pdmH1N1 positive(200 cases)and B Victoria(BV)positive(200 cases)by whole-genome sequencing and analyzed by ddPCR for viral load in samples before isolation,and isolation results were verified by hemagglutination(HA)assay and hemagglutination-inhibition(HI)tests.Probit regression analysis was used to calculate the isolation viral load limit with a 95%probability level by SPSS 19.0 software.The results showed that the isolation limit of viral load was 4.9×10^(4)(95%CI:2.5×10^(4)–9.0×10^(4))copies/mL for pdmH1N1 and 1.9×10^(4)(95%CI:7.8×103–3.6×10^(4))copies/mL for BV.The isolation rate of clinical samples is positively correlated with the viral load in clinical samples,which can be used for viral culture,providing important guidance for daily work. | Yimeng Liu Jiachen Zhao Xiaomin Peng Guilan Lu Weixian Shi Zhaomin Feng Hui Xu Shujuan Cui Yang Pan Daitao Zhang Peng Yang Quanyi Wang | 2022 | Biosafety and Health2022，4，5： | 0 |
