The clinical manifestations of genital herpes can be divided into primary genital herpes and non-primary primary genital herpes. Genital herpes has an incubation period, usually 3-14 days, and may manifest as clusters or scattered small blisters around the external genitalia or anus, which may break down to form vesicles or ulcers after 2-4 days and may be painful. The lymph nodes in the groin may be enlarged and have pressure pain. Some patients may have fever, headache, and malaise, and the course of the disease can last 2-3 weeks. These are symptoms of non-primary, incipient genital herpes, and recurrent genital herpes. In primary herpes, the rash can recur after the skin breaks down. Recurrent genital herpes is less severe than the original primary lesions and has a shorter duration. The rash may be preceded by a local burning sensation, or a pins-and-needles sensation or abnormal sensation, and small blisters may form around the external genitalia and anus, which can soon become eroded, that is, shallow ulcers, with milder self-conscious symptoms, and the course of the disease can last more than 1 week.
