"涂抹香油或酒精刺激蜱虫会使其加速分泌唾液，增加被蜱虫携带病原体感染的风险。"在6月5日国 家卫生健康委召开的新闻发布会上，中国疾控中心研究员刘起勇解释称，蜱虫被刺激后还会收缩身体， 甚至导致口器断裂并残留在皮肤内，引起局部炎症、感染等。 涂抹香油或酒精能让蜱虫自行脱落、被蚊子叮咬后涂抹牙膏或肥皂水就能好、戴眼镜早会让近视度 数涨得更快、一些产品能够使眼轴回退消除近视……随着季节变化、暑假来临，一些"应季"的谣言卷土 重来。 随着天气变热、湿热交蒸，自然界蚊虫增多，夏季健康问题呈现出新特点，人们在处理时会存在一 些误区。刘起勇说，被蚊子叮咬后涂抹牙膏或肥皂水预防传染病是没有科学证据支持的。牙膏和肥皂水 仅能缓解叮咬后的瘙痒症状，无法杀灭其携带的登革热病毒和疟原虫等病原体，因此无法阻止感染。被 蚊虫叮咬后，若出现发热等不适症状，需及时就医。 "常有人问：蚊子是不是偏爱某种血型，比如O型血？目前科学研究证实血型与蚊子吸血偏好没有 明确的关联。"刘起勇介绍，蚊子选择叮咬对象时，更依赖实际生理特征和环境因素。人体呼出的二氧 化碳是蚊虫定位的核心信号，代谢旺盛的人，如孕妇、运动后人群等更容易被蚊虫叮咬。 "主流的激光近 ...
