An overview of Human Papilloma Virus
Languages of publication
Cervical cancer is the second commonest cause of cancer among women. According to the World Health Organization (WHO) data, in 2006 there were 1.4 million women who were suffering from cervical cancer and 80% of deaths among them were of women from developing countries. Genital infection with Human Papilloma Virus (HPV) is one of the major etiological factors for developing cervical cancers in almost all countries (World Health Organization, 2005). Papilloma viruses were first identified, cloned and sequenced from cervical tumor specimens and were subsequently established as important causative agents for the development of cervical cancer. Differences in prevalence rates are observed worldwide. Infection is more common in sexually active young women of 18-30 years and a reduction in acquisition of infection is observed after 30 years. The situation of Cervical cancer in Sri Lanka is identified as the second most common cancer among women in Sri Lanka and approximately 7.74 million women are included in the risk category. It is reported that nearly 850 die from cervical cancer each year.
