What is HPV made of?
Papillomaviruses are small, non-enveloped, icosahedral DNA viruses that have a diameter of 52–55 nm. The viral particles consist of a single double-stranded DNA molecule of about 8000 base-pairs (bp) that is bound to cellular histones and contained in a protein capsid composed of 72 pentameric capsomers.

What is the life cycle of HPV?
HPV DNA replication during its life cycle occurs in three separate phases (reviewed in [1, 2]). After viral entry into the cell nucleus and the activation of viral gene expression, the viral genome copy number increases to several hundred copies per cell during the initial phase of genome amplification.

Cervix: HPV and cancer symptoms
- pain during sex.

Where is HPV found?
HPV lives in thin, flat cells called epithelial cells. These are found on the skin’s surface. They’re also found on the surface of the vagina, anus, vulva, cervix and head of the penis. They’re also found inside the mouth and throat.
Does HPV occur naturally?
HPV is common—but it can cause everything from genital warts to cancer, making it a virus you really don’t want to catch.
