High blood pressure and diabetes are not the main causes of herpes, but those with high blood pressure and diabetes may be prone to herpes, mainly related to the disease-induced autoimmunity. Herpes is a general term for a group of diseases, and the common clinical types include herpes simplex and herpes zoster. Herpes is mainly caused by human herpes virus infection, and low immune function, skin trauma, overwork, etc. are disease triggering factors. For some patients with hypertension and diabetes mellitus, they may be prone to herpes, which is mainly related to the decline of autoimmunity caused by the two chronic diseases. Since herpes can be transmitted through direct contact, indirect contact, sexual contact, and mother-to-child transmission, those diagnosed with the disease need to cooperate with their doctors to isolate and treat the disease. For those who are clearly suffering from hypertension and diabetes, they should be treated with blood pressure and blood sugar lowering medications as prescribed by the doctor. Avoid close contact with herpes patients in daily life. It is recommended that those who are diagnosed with the disease be treated with medication under the guidance of a physician, and not to use medication or prescriptions indiscriminately on their own. People with herpes need to strengthen the skin care, to avoid foreign body friction stimulation.
