Psoriasis is a non-contagious skin condition and it can't be spread through contact, because it can be a genetic disease.
There are a number of different types of psoriasis. Plaque Psoriasis is the most common form of psoriasis. It usually appears as patches of dry, raised, red skin covered with a flaky white build-up.
Other Types of Psoriasis differ symptoms and levels of severity. These include, Guttate Psoriasis, which commonly starts in childhood; Erythrodermic Psoriasis which is a particularly inflammatory type of psoriasis and the least common form of the disease; Pustular Psoriasis which is characterized by the appearance of non-infectious, pus-filled blisters and is sometimes accompanied by severe itching, fever, or chills; Palmoplantar Psoriasis which is similar to postular psoriasis and develops in the fleshy areas of the hands or feet and finally Scalp Psoriasis, where lesions may appear on the hairline.
