疱疹性咽峡炎是由肠道病毒引起的以急性发热和咽喉部疱疹为特征的急性传染性疾病。疱疹性咽峡炎发病率高，四季均可发病，春夏季为主。该病多见于6岁以下学龄前儿童。
疱疹性咽峡炎患者通常表现为高热，一部分孩子可能发生高热惊厥。咽喉部疱疹使宝宝吞咽时疼痛，可表现为哭闹、拒食、拒奶、流涎。家长也可以看到宝宝咽部的疱疹，疱疹中心是灰白色的，周围有明显的红晕，1～2天后破溃形成小溃疡，咽痛比较明显。
居家护理应注意
一旦发现孩子患上疱疹性咽峡炎，家长护理孩子时要注意以下几点。
注意定时开窗通风，保持室内空气新鲜。
鼓励患儿多饮水，及时更换被汗浸湿的衣服。
疱疹性咽峡炎引发的高热有可能引发惊厥，尤其存在热性惊厥家族史的患儿发生惊厥的可能性会更高一些。
患儿高热时，应及时退热。退热措施包括药物及物理降温。体温比较高时，可遵照医嘱给予布洛芬或对乙酰氨基酚等口服退热药物。物理降温如贴退热贴、头部冷敷、温水擦浴等。但应注意两次退热药物的间隔时间要大于4小时，避免频繁使用退热药物导致药物副作用。
应保持宝宝口腔清洁，饮食选择清淡流质食物，如鸡蛋羹、小米粥、豆浆或者菜汤，可以选择偏凉食物，避免食物过热增加疼痛。饭前饭后用生理盐水漱口。
家长应密切观察患儿精神状况和饮食状态，如有无精神差、嗜睡、烦躁不安、面色苍白等，应注意并发症的发生。
拒食、拒奶宝宝可能出现脱水，家长要提高*惕。一旦发现孩子脱水，家长要及时为其补充液体。
此外，家长需要关注孩子的饮水和饮奶量，如果孩子进食水的量很少，同时尿量明显减少，哭的时候没有眼泪，不发热时手脚也凉，提示孩子有可能脱水。一旦发现孩子存在上述情况，建议及时就医。
患儿用过的玩具、餐具或其他用品应彻底消毒。一般常用含氯的消毒液（如84消毒液）浸泡、清水冲洗，或煮沸消毒。酒精消毒效果不佳。
