"中国既往没有过输入性基孔肯雅热引发大流行的案例，对该病的基础免疫力缺失，因此病毒传播会快 于其他流行区域。"张文宏向记者解释称。 不过即便如此，他认为，如果及时采取有效迅速的措施，目前南方部分地区应该仍处于控制疫情的有效 窗口期，仍能阻止感染风暴的进一步形成并阻止病毒向周边区域扩张。 根据广东省佛山市各区最新的通报，截至7月24日，佛山市5个区已累计报告基孔肯雅热确诊病例超过 4000例。目前，佛山当地已经对感染患者采取了防蚊隔离措施。 据广东省佛山市各区最新的通报，截至7月24日，佛山市5个区已累计报告基孔肯雅热确诊病例超过4000 例，其中顺德区报告确诊病例3627例，均为轻症病例。据智通财经，目前，广州、阳江、湛江等地均出 现了基孔肯雅热病例。世界卫生组织25日警告，基孔肯雅热病毒正在全球多地扩散，已有119个国家报 告病例，约550万人面临感染风险。 针对我国近期南方部分地区突然增多并出现外溢的基孔肯雅热病例，国家传染病医学中心主任、复旦大 学附属华山医院感染科主任张文宏教授首次发声。他接受记者采访时解释了为何此次病毒在我国南方部 分地区传播较快。 对此，张文宏表示，人也是该病毒的传染源，会帮助病毒 ...

日前，广东省佛山市召开新闻发布会称，为应对基孔肯雅热疫情形势发展，佛山已指定53家二级及 以上医院作为定点收治医院，同时将防蚊隔离床位从3696张扩容至7220张，为确诊病例提供诊疗和 住院治疗服务。 7月23日，在国家卫健委举行的新闻发布会上，中国疾控中心介绍，近期，我国南方个别城市发生基 孔肯雅热输入疫情并引发本地传播。但强调基孔肯雅热可防可控可治，主要通过伊蚊叮咬传播，没有 人传人迹象。 截至7月24日，佛山市基孔肯雅热感染已超3600例，疫情仍处在高位平台期，但尚未发现本地续发 病例，疫情输入风险总体可控，且患者均为轻症。一些人对于患者为何需要隔离产生疑惑，既然不会 人传人，为何仍需采取隔离措施？ 对此，相关专家对第一财经记者表示："基孔肯雅热的传播途径是人-蚊-人，虽然病毒不会直接人传 人，但人也是传染源——人感染病毒后大部分患者都会出现病毒血症，若不进行防蚊隔离，叮咬了感 染者的蚊子体内病毒增殖，再通过叮咬他人，形成社区传播。由于病毒传播速度极快，将患者隔离， 能有效减少病毒进一步传播扩散的风险。" 2025.07. 25 本文字数：929，阅读时长大约2分钟 作者 | 第一财经 钱童心 国家感染 ...
