The main reason for this is the fact that it’s not just about infection, but also about the environment and the immune factors that can trigger the disease.
1. Infection factors: flat warts caused by human papilloma virus infection, in the appropriate conditions, will invade the skin, infected skin epidermal cells, and in its replication, proliferation. If the vulva is infected with this virus, it will lead to the formation of vulvar flat warts.
2. environmental factors: if the patient often close contact with people with vulvar flat warts, long-term in the environment of the virus breeding and direct contact, may lead to the transmission of the disease.
3. immune factors: if the patient’s immunity is low, such as the patient is AIDS patients, resistance to the virus is weak, can increase the chance of vulvar flat warts.
There are a lot of reasons for this, so you should go to the hospital in time to have a checkup and get a clear diagnosis.
