How does one get flat warts around the anus?

The main causes of anal flat warts include: 1. Unprotected sexual activity: This may result from unsafe sexual practices, especially unprotected sex with an infected individual, which can easily lead to cross-infection with the virus and subsequently trigger flat warts. 2. Weakened immune system: A compromised immune system is also a significant factor in the development of anal flat warts, as it makes the body more susceptible to viral infections. 3. Close contact: Close contact with an infected person, especially using items previously used by the infected individual, may also lead to viral infection and the development of flat warts. 4. Personal hygiene habits: Long-term neglect of cleanliness and hygiene in the anal area may promote bacterial growth, thereby increasing the risk of developing flat warts.
