There is no such thing as which is more serious, herpes simplex virus type 1 or type 2. The severity of the disease varies among different groups of people due to differences in their own immunity, and varies from person to person.
Herpes simplex virus type 1 mainly causes skin and mucous membrane infections outside the genitals, while herpes simplex virus type 2 mainly causes infections in the genital area. The lesions begin with a burning or tense sensation, followed by erythema and clustered blisters. Episodes may recur after exposure to triggers such as fever, cold, sun exposure, exertion, and mechanical stimulation.
The severity of herpes simplex infection varies from person to person because of individual differences in clinical manifestations. When herpes simplex virus infection occurs, it is important to consult a doctor promptly for standardized treatment.
