| 2 | Epidemiology and characteristics of identified early mpox cases in Guangdong Province,China:Implications for prevention and control显示文摘In June 2023,the 2022 global mpox(monkeypox)outbreak began to affect Guangdong Province,one of the first regions in China's Mainland to report mpox cases.By July 10,2023,93 mpox cases had been reported in Guangdong Province.This study describes the epidemiological characteristics of these patients by collecting and analyzing data on demographics,sexual behavior,medical history,travel history,clinical symptoms,and diagnostic pathways and processes.The 93 mpox cases were all men aged 20-48 years,95.70%were men who have sex with men(MSM),and 48.39%were HIV-positive.A few cases were married(to women)or living with children.The rash was present in almost all cases(98.91%),with the most common sites being the genital and perianal areas(70.33%).Intimate sexual contact was suspected to be the main route of infection,with a median incubation period of 8.5 days(IQR 5.0–11.8).The number of cases increased rapidly,and most patients had no history of international travel,suggesting sustained community transmission within the MSM population in Guangdong Province.In addition,93.55%of cases were detected by medical institutions,and more than half of these patients had two or more hospital visits before being diagnosed as an mpox case,indicating that clinicians need further training to increase their sensitivity to mpox.Targeted interventions should prioritize MSM while remaining vigilant for transmission to other populations,such as women and children. | Yinan Zong Yuwei Yang Dongfeng Kong Jianxiong Xu Zimian Liang Fengxiang Shi Jianhua Huang Min Kang Haojie Zhong Wenjia Liang Yan Li | 2023 | Biosafety and Health2023，5，6： | 0 |
| 3 | Estimating Costs of the HIV Comprehensive Intervention Using the Spectrum Model--China,2015-2019显示文摘Introduction:In order to facilitate human immunodeficiency virus(HIV)treatment and prevention,the resource needs for HIV national strategic planning in developing regions were estimated based on Spectrum,the universal HIV costeffectiveness analysis software.Methods:Based on the theoretical framework of Spectrum,the study developed a cost measurement tool for HIV,and calculated the cost of HIV prevention and control in 6 sampled cities in China during 2015–2019 using the Spectrum model.Results:From 2015 to 2019,the average annual costs for HIV prevention and control for Shijiazhuang,Yantai,Ningbo,Zhenjiang,Foshan,and Wuxi cities were 46.78,47.55,137.49,24.73,74.37,and 58.30 million Chinese yuan(CNY),respectively.The per capita costs were 4.37,6.73,17.33,7.77,17.56,and 8.91 CNY,respectively.In terms of the cost structure,the ratio of preventive intervention funds to therapeutic intervention funds(antiviral treatment)varied in sampled cities.Discussion:Developing comprehensive and systematic HIV fund calculation methods can provide a research basis for rational resource allocation in the field of HIV. | Youran Zhang Lili Wang Zhen Jiang Hongjing Yan Xiaoxia Liu Jing Gu Guoyong Wang Xiaosong Cheng Qiyan Leng Qisui Long Zimian Liang Jing Wang Liang Liang Yanchao Qiu Lin Chen Hang Hong | 2022 | China CDC weekly2022，4，25： | 0 |
