People with HIV at higher risk of COVID reinfection: CDC_我的网站

A |     近日，为推动“中小学科学教育示范区”建设，省科协、省教育厅共同启动实施“辽宁省中小学生科技助苗行动”。         　　“科技助苗行动”旨在弘扬科学精神和科学家精神，探索青少年科学教育有效途径和人才培养创新模式，推动构建社会各方科教资源有机融合的“大科学教育”工作格局，推进教育科技人才体制机制一体改革，助力科技强省、教育强省建设。         　　在科技助苗行动启动仪式上，举行了中小学科技副校长聘任、科普教育基地与中小学校合作签约等活动。中国工程院院士王国栋代表科技工作者发出倡议，号召全省广大科技工作者传承科学家精神，提升科普能力，践行志愿服务，做青少年科技成才的引路人和铺路石。    People with HIV are at increased risk of being reinfected with the virus that causes COVID-19, according to new federal data.Researchers from the Centers for Disease Control and Prevention and the Chicago Department of Public Health followed adult residents in Chicago from their first reported infection from March 2020 through the end of May 2022, according to the report published Wednesday by the CDC.The team compared COVID test laboratory data and COVID vaccine administration data to Chicago's Enhanced HIV/AIDS Reporting System.About 5% experienced reinfection among more than 453,000 Chicago residents who tested positive for the virus.Rates of reinfection were higher among people with HIV (6.7%) than among people without HIV (5.2%).People with HIV are more likely to have completed a primary COVID vaccine series plus a booster before their reinfection -- 31.8% versus 27% for those without HIV.Reinfection rates were consistently higher throughout the pandemic for people with HIV and were highest during the original omicron variant phase, according to the report."Understanding if persons with HIV have a higher risk for SARS-CoV-2 reinfection may help tailor future COVID-19 public health guidance," the authors wrote. "[Persons with HIV] should follow the recommended COVID-19 vaccine schedule, including booster doses, to avoid SARS-CoV-2 reinfections."Those who were reinfected were more likely to be male, older and Black or African American compared to those without HIV, the study found.People with HIV were also less likely to have been unvaccinated at the time of their first infection compared to people without HIV.The report notes the findings are a reminder about the risks of reinfection for those who are immunocompromised.HIV can weaken the immune system, infecting and destroying CD4 cells, which causes the white blood cell count to drop and compromises the immune system.This means that people with HIV are susceptible to COVID infection especially those who are not on antiretroviral therapy (ART).ART is a combination of drugs that suppresses a person's viral load until HIV Is virtually undetectable. The ability of ART to control viral replication has been shown to greatly improve immune system function, studies show."Evaluating the association between HIV infection and SARS-CoV-2 reinfections using surveillance data can help strengthen public health recommendations including the need for extra doses as part of a primary series, booster doses of vaccine, and optimized ART in [persons with HIV]," the authors wrote. "Tailored guidance and prevention messaging for [persons with HIV] can help reduce the elevated risk we identified in this analysis and limit continued SARS-CoV-2 transmission."。         　　据了解，为推动科技助苗行动的实施，科协系统、教育部门、高校（院所）、科普基地、各级学会、中小学校等将深度合作，建立校内外科学教育资源衔接机制，让资源更加开放共享；创新青少年科技赛事活动和科学实践活动，激励更多的优秀科创少年脱颖而出；积极探索适应青少年科学教育的新思路和新方法，推动打造校园“科技节”“科学节”等一批有影响力的校园科普特色工作品牌和活动品牌。                    责任编辑：李丹。
