Psoriasis, although it is also a skin disease, is not caused by some fungi. It is useless for patients and friends to blindly use some ointment to inhibit fungi, and it will even cause further damage to the skin. So, what is the history and current situation of psoriasis?

The ancient Greeks believed that psoriasis was cursed by many gods, and forced patients with psoriasis to ring the bell to prevent infection. Among the known celebrities, Lin Biao, Stalin and Zeng Guofan suffered from this disease. Zeng Guofan suffered from severe psoriasis, and he had to be tickled by his maid every night to fall asleep. He never recovered for life. In the past, because there were more housewives and catering workers, it was once thought that it was related to the detergent they used to wash their hands.

At that time, society thought that psoriasis was contagious, and in order to prevent guests from being infected by eating food containing dander by mistake, these employees were all dismissed from the restaurant. At present, it is generally believed that the stress of life is too great, which leads to the endocrine disorder of the disease-causing person, thus affecting the body's immune system. Therefore, doctors sometimes prescribe vitamin B miscellaneous for patients to help relieve stress; Some doctors also think that patients should do more aerobic exercise, so that the body's natural regulation mechanism can adjust itself through exercise.

In Hong Kong, many students and teachers have local psoriasis, mainly in the palms, arms, legs or shoulders. In the United States, a pharmaceutical factory recently invented an injection, which can control the course of serious patients and make their skin smooth again. This injection was also introduced to Canada for clinical testing in 2116. However, this injection can't cure psoriasis, and once the injection is stopped, the problem will reappear immediately.

according to the survey, the incidence of psoriasis accounts for 1.1% ~ 3% of the world population, and the incidence of yellow people is 1.1% ~ 1.3%. The incidence of psoriasis in the population is obviously higher in whites than in yellow people, followed by black people. As of 1998, the number of patients with psoriasis in China has reached more than 2.8 million. According to the survey in the United States in recent years, its incidence rate is 2.6%, with 6-7 million patients, far higher than that in China.

Because it is stubborn and difficult to treat, it is still listed as an important research topic in the field of dermatology in the world, and it is one of the key diseases to be prevented and treated in dermatology all over the world. At the national cooperation conference on psoriasis prevention and treatment held in recent years, the participating experts agreed that "the combination of traditional Chinese medicine and western medicine is the direction of psoriasis prevention and treatment." Western medicine anticancer drugs and hormonal drugs have serious side effects and should be avoided as much as possible. "

Its skin lesions are characterized by red papules or patches covered with layers of silvery white scales, which have obvious seasonality. Most patients get worse in spring, winter and summer. The total prevalence rate in China is 1.72‰, with males more than females, northern more than southern, and urban higher than rural. The first onset age is 21-39 years for men and 15-39 years for women. The incidence rate has been on the rise in recent ten years. It is considered to be related to industrial pollution and working environment.
