人民网北京9月4日电 （记者乔业琼）据中疾控微信公众号消息，急性出血性结膜炎，俗称"红眼 病"，是一种主要由肠道病毒引起的急性传染性眼病。这种病以结膜高度充血为主要临床特征，常伴有 眼睛流泪、畏光、分泌物增多等症状，症状通常在感染后1-2天内出现，持续1-2周。作为一种常见眼 病，在公众认知中，仍存在不少误区。 误区一：看一眼就会被传染 在红眼病的认知误区中，最具代表性的莫过于"与红眼病患者对视，就会被传染"。事实上，这种说 法并无科学依据。 红眼病的传播主要通过接触被污染的物品（如毛巾、手帕、洗脸盆、门把手等）；或直接接触患者 眼部分泌物而传播；也可以通过受污染的水传播。例如，游泳池的水如果消毒不当，游泳者可能感染病 毒而得红眼病。因此，预防红眼病的关键在于做好个人卫生，勤洗手，避免接触患者使用过的物品。 误区二：眼药膏和包扎眼睛能加速康复 在红眼病急性期，使用眼药膏或包扎眼睛都是不恰当的处理方式。因为眼药膏质地黏稠，会在眼表 形成一层薄膜，阻碍眼部分泌物的排出，不利于炎症的消退。至于包扎眼睛，会使眼部处于相对封闭环 境中，导致局部温度升高，湿度增大，反而有利于病菌繁殖，进而加重感染。 误区三：使用抗生素能 ...
