HPV prevalence Study (2009-2013)
POPULATION PREVALENCE OF HIGH RISK HUMAN PAPILLOMA VIRUS (HPV) INFECTION IN SEMI-URBAN AND RURAL AREAS ADJOINING CHENNAI, INDIA FOLLOWED BY ONE YEAR PERSISRENCE STUDY
Today, HPV infection is considered to be the major factor in cervical carcinogenesis. Since there was no documented data on prevalence of HPV in the community, we conducted a study to ascertain the prevalence of HPV infection in Tambaram and ChengelpetTaluks of Kanchipuram District, Tamilnadu, between 19.02.2009 and 31.12.2009.1525 cervical samples were collected and the overall prevalence rate of HPV is found to be 12.7%, the most common type being HPV 16(27%).
A follow up study to find the persistence of virus at one year interval was just completed and this will provide first such data in Indian population.137 samples have been collected (71% compliance for follow-up) out of which 38 (29.1%) are persistently positive for HPV infection. Genotyping of the positive samples showed type 16 to be the most common type.
