Psoriasis is only relatively hereditary but not absolutely hereditary. In domestic and foreign investigation reports, patients with a family history of psoriasis are about 10%-30%. Although individual patients have a family history, but the psoriasis patients with a family history are only those who have susceptible genes in the family population, because such genes are inherited from the next generation and are easily induced to get psoriasis. Family history is only one of the reasons for the onset of psoriasis. There are also many acquired factors that determine the onset of psoriasis, such as: season, climate, environment, virus, infection, mental trauma, endocrine disorders, immunological abnormalities, etc., all of which can stimulate the onset of psoriasis.

It is found that bacteria, especially Streptococcus b haemolyticus infection, can easily induce punctate, arthritic and erythrodermic psoriasis, and this situation is especially prominent among adolescent psoriasis patients. It has been found that some products of bacteria, which become superantigens, can activate T cells and make them produce cytokines, which act on keratinocytes and promote excessive keratinocyte proliferation, aggravating the condition of psoriasis patients. In autumn, winter and early spring when the seasons are cold, the condition of psoriasis patients will be aggravated by colds, especially for those who have symptoms of sore throats. Therefore, psoriasis patients must strengthen preventive measures during the season when colds are common, enhance the body’s immunity to bacteria and viruses, and treat colds as soon as they occur.
