FIG 3.

Distribution of HPV types in organs of healthy human subjects. The numbers represent the HPV types. High-risk types are marked in red and low risk types in blue. N, unclassified HPV type. The colored boxes represent different organs (vagina, blue; gut, yellow; skin, red; mouth, green). The numbers in a specific box mean that the corresponding HPV type was found in the organ(s). For example, “1” means that type 1 HPV was found only in the mouth, and “28” means that type 28 HPV was found in the skin, gut, and vagina simultaneously.
