皮肤病都是可以传染的吗？

这些皮肤病是不传染：

1、过敏性皮肤病：像皮炎、湿疹一大类，属于自身皮肤敏感或者过敏，非常瘙痒，会出现丘疹、水疱、糜烂、抓破、肥厚等，看着非常可怕，但是不会传染。

2、色素性皮肤病：像白癜风、黄褐斑，影响美观，但不会传染。

3、皮脂腺、红斑鳞屑性疾病：如痤疮、银屑病、玫瑰糠疹等不会传染。

4、自身免疫性疾病：红斑狼疮、天疱疮、血管炎等。

哪些皮肤病具有传染性？

1、病毒性皮肤病：如常见的单纯疱疹（上火）、水痘、带状疱疹；各种疣（寻常疣、扁平疣等）、麻疹、风疹、传染性软疣、手足口病、口蹄疫等，可通过直接接触或呼吸道传播。

2、细菌性皮肤病：如胶疮疮、麻风、皮肤结核等均可通过接触而传染。儿童卫生不做好最易患脓疱疮，直接或者间接都可传染；

3、真菌性皮肤病：这是一类常见病，由各种真菌感染引起，如头癣、手癣（鹅掌风）、足癣（脚气）、甲癣（灰指甲）、体股癣、花斑癣（汗斑）等可通过公共用具、衣物、鞋袜、浴具传染，如头癣可通过理发用具相互传染、手足癣可通过鞋袜传播。

4、性传播疾病：不用说，这类疾病绝对传染，淋病、梅毒、艾滋病等都可通过性行为而传播。

5、其他：由疥螨引起的疥疮、虱子引起的各种虱病（头虱、阴虱和体虱等）都具有很强的传染性。

皮肤病的传染方式：直接接触传染和间接接触传染

直接接触传染：是通过直接接触病人或患病动物的皮肤、血液、体液和分泌物（如痰液、粪便、唾液、尿液、渗出液等）而传染；

间接接触传染：是通过接触病人的用具（如餐具、衣帽、被褥、洗漱用品、鞋帽、毛巾等）而传染。

皮肤病并非接触后就一定会被传染，这是因为人体具有一定免疫力。当免疫力下降时，如在体弱、慢性疾病期、长期使用免疫抑制剂及激素、肿瘤等条件下，被传染的机会则会大大增加。
