HPV = Human Papilloma Virus More than 170 types of HPV Transferred via skin on skin contact Can lead to cancer Some types show symptoms, others do not
Non-enveloped DNA Virus Family: Papillomavirus family Establish only on basal keratinocytes of skin/mucous membrane HPV types 6 and 11: cause genital warts HPV types 16 and 18: may progress to precancerous lesions and invasive cancer
generally skin contact: perinatal genital infections hands shared objects (toys) blood surgery
Cancer Respiratory papillomatosis Immuno-comprimised Genital wart Skin warts Types of warts: Common skin warts plantar warts subungual or periungual warts flat warts
Incidence of HPV associated cancers in USA ( )
Estimated global prevalence = 11.7% (women) Sub-Saharan Africa = 24% Eastern Europe = 21.4% Latin America = 16.1% Highest percentage of cases of HPV in women
Estimated deaths since 2014: Worldwide = United States = 11139
Vaccine: Gardasil Gardasil 9 Cervarix Education Social mobilization Screening Papillative care Use & promotion of safe sex – condoms Male circumcision Protection against HPV types: 6, 11, 16 & 18 Protection against HPV types: 16 & 18
Currently no specific treatment for HPV Virus normally clears by itself – within 2 years Genital warts: Physical ablation – e.g. Excision, cryosurgery, etc. Topical agents – e.g. 0.15–0.5% podophyllotoxin solution Cancer: chemotherapy
DRACO drug = early stages Alferon N = drug to treat genital warts Lopinavir = antiretroviral – of the protease inhibitor class
