Human papillomavirus (HPV)
Each year, human papillomavirus (HPV), a leading cause of cervical cancer, kills more than 250,000 women worldwide, mostly in developing countries. With early detection, treatment for HPV strains that cause cervical cancer is available. There are currently two available vaccines against the major disease-causing strains of HPV, which have been shown to be at least 95 percent effective in preventing persistent HPV infection and 100 percent effective in preventing vaccine type-specific cervical lesions in women aged 16 to 25.
