猫癣的界定，是否会传染？Can feline ringworm be contagious?
猫癣是一种常见的猫皮肤疾病，具有较高传染性，它由真菌感染引起，会破坏猫皮肤和毛发中的角蛋白，发生部位多为头部和躯干。
猫感染猫癣首先能看到皮肤局部脱毛、变红，略显干燥，甚至产生白色皮屑、渗出液或结痂，但早期精神食欲都好，症状轻的是可以自愈的，一般要两三个月，如果病程发展严重，这些癣可能遍布猫咪全身，且极有可能反复发作；
而人一旦感染上猫癣，初期会出现红包或者小红点，随着抓挠，皮肤表面会出现典型的红色圆环状凸起，伴有脱皮-一这就是传说中的“钱癣”或“金钱癣”，可能延续数月。
感染猫癣的真菌大部分(95%以上)都是由犬小孢子菌引起，极少数由须毛癣菌引起。
猫癣之所以是人畜共患病，是因为传染源十分广泛，污染源、病人或者病猫都可以是万恶的传染源。
并且孢子菌大量存在于空气、土壤、水和腐败的有机物中，通过摩擦、抓痒或抚摸等接触行为，在动物和污染源、动物与动物、动物与人之间都可以达成直接或间接的传染。
Cat ringworm is a common cat skin disease with high infectivity. It is caused by fungal infection and can destroy the Keratin in cat skin and hair. It occurs mostly in the head and trunk.
When a cat is infected with cat tinea, it can first cause local depilation, redness, and slight dryness of the skin, and even produce white dander, exudate, or scabs. However, in the early stages, the mental appetite is good, and those with mild symptoms can self heal, usually taking two to three months. If the disease progresses seriously, these tinea may spread throughout the cat's body and are highly likely to recur;
Once a person is infected with feline ringworm, red envelopes or small red spots may appear in the initial stage. With scratching, typical red circular protrusions will appear on the surface of the skin, accompanied by peeling - this is the legendary "ringworm" or "ringworm", which may last for several months.
The majority (over 95%) of fungi infected with feline tinea are caused by Microsporium canis, with very few being caused by Trichophyton.
The reason why feline ringworm is a zoonotic disease is because the source of infection is very extensive, and pollution sources, patients, or sick cats can all be the source of all evil infections.
Moreover, spore bacteria are abundant in air, soil, water, and decaying organic matter. Through contact behaviors such as friction, scratching, or touching, they can achieve direct or indirect transmission between animals and pollution sources, animals and animals, and animals and humans.
