转自：北京日报客户端 12月25日，中国疾控中心发布全国急性呼吸道传染病哨点监测最新情况，我国流感活动总体处于中流行 水平，各省份流感病毒检测阳性率均呈下降趋势。 12月15日至21日的监测结果分析显示，检出均为已知常见病原体，没有发现未知病原体及其导致的新发 传染病。近期流感病毒为主要检出病原体，我国流感活动总体处于中流行水平，各省份流感病毒检测阳 性率均呈下降趋势，其中华北、东北、西南和西北地区大部分省份已降至中流行水平，华东、华南和华 中地区大部分省份仍处于高流行水平；学校聚集性疫情报告起数显著下降。 呼吸道合胞病毒检测阳性率呈上升趋势，北方省份呼吸道合胞病毒检测阳性率连续3周上升，南方省份 呼吸道合胞病毒检测阳性率处于相对低水平。鼻病毒检测阳性率有所波动。新型冠状病毒和其他监测的 呼吸道病原体检测阳性率总体处于低水平。 中疾控介绍，当前，我国呼吸道传染病仍处于高发季节，流感疫情处于中流行水平，呼吸道合胞病毒、 鼻病毒亦存在一定水平活动。为防范呼吸道传染病疫情，建议托幼机构、中小学校、养老院等重点机构 和场所做好健康监测，及时发现和处置聚集性疫情，降低疫情影响。 来源：北京日报客户端 ...

肺炎开始的症状也是咳嗽、发烧、没力气，如果出现以下情况要及时就诊： 今天，国家卫生健康委召开新闻发布会，介绍当前我国呼吸道传染病有关情况。当前，我国呼吸道传染 病疫情仍处于高发季节。从中国疾病预防控制中心发布的监测报告来看，流感病毒是我国急性呼吸道传 染病主要流行的病原体，呼吸道合胞病毒、鼻病毒亦存在一定水平活动。本周我国流感活动出现下降， 但总体仍处于高流行水平。 从哨点医院流感病毒检测阳性率情况来看，门急诊流感样病例和住院严重急性呼吸道感染病例中，流感 病毒检测阳性率均居首位。甲型H3N2亚型为主要流行毒株。 从各省监测情况来看，南方部分省份流感疫情达峰时间略晚于北方。秋冬季流感高发主要是因为受气温 下降等因素影响，冬季寒潮较多，室内外温差大，寒冷空气会刺激并损伤呼吸道黏膜，使其防御细菌、 病毒的能力在短时间内大幅下降。同时，为抵御严寒，人们常采取长时间紧闭门窗的方式，致使室内空 气流通不足，增加了流感病毒等呼吸道病原体在家庭、办公场所等人群聚集环境中传播的机会。总体来 看，各省份流行强度处于动态变化中，请重视并做好个人和家人防护措施。 此外，专家提示，流感不能被当作普通感冒看待。不能被当成"小毛病"硬抗 ...
