洛杉矶郡卫生部本月5日公布，洛杉矶爆发麻疹疫情。一名未接种疫苗的国际访客过境，导致4名居民感染。1月26日至2月1日之间，曾去过西洛杉矶和南湾以下地点的民众，可能暴露在麻疹病毒下。
这几名感染麻疹的居民在传染期访问了30多个地点，主要在西洛杉矶和南湾地区。洛郡卫生部门警告，在相同日期和时间访问这些地点，且未接种麻疹疫苗或免疫力低下的人，在7至21天内有感染麻疹的风险。
感染麻疹病毒后，会出现发烧、皮疹、咳嗽、流鼻涕和红眼的症状。民众应该进行自我检测，结合自身情况联系医生。
世界卫生组织信息介绍，麻疹病毒传染性强，可通过呼吸道飞沫、气溶胶和直接接触传播。从感染到出疹的平均间期是14天（7~18天）；患者在出疹前2~3天至出疹后1~5天内最具有传染性。
根据美国疾病控制和预防中心的数据，5岁以下的儿童，20岁以上的成年人，孕妇以及免疫系统较弱的人容易受到包括肺炎和脑炎在内的严重并发症的影响。更常见的麻疹并发症包括腹泻和耳部感染，可导致儿童永久性听力损失。
