HPV

The human papilloma viruses (HPVs) are DNA double strand viruses and of small size (approximately 8000 pairs of bases) that have cohabited with the human specie over dozens of millennia suffering relatively few changes in their genetic composition. These nearly 100 different types of papillomavirus identified express a characteristic tropism.  The best known clinical expression of the viral infection is condylomas or genital warts, associated in approximately 90% of the cases by infections by HPVs 6 and 11 and, more rarely, with HPVs 42 and 16. Infection by HPV is basically a sexually transmitted disease. As such, both men and women are involved in the epidemiological chain of infection and are able at the same time to be asymptomatic carriers, transmitters and also victims of the infection by HPV.
