Human Papillomavirus (HPV) is a common sexually transmittable virus. Most HPV infections do not cause symptoms whilst several viral strains could lead to genital warts and increase the risk of cervical cancer. HPV-16 and HPV-18 are of the most high risk genotypes within the HPV family. Currently there are vaccines that can prevent HPV. The bivalent, quadrivalent and 9-valent vaccines are protective against both HPV-16 and HPV-18. The new 9-valent HPV vaccine has an extended protective coverage to 7 other HPV types.
The map shows the crude incidence rate of cervical cancer and the prevalence ratio of HPV-16 and HPV-18 in countries in the Asia Pacific. A higher incidence rate is found in countries of south and south-east Asia. Generally prevalence of HPV-16 is much higher than HPV-18 in most of the countries. Currently HPV vaccine is not commonly used in most of the countries. Regular screening remains the most effective means to prevent cervical cancer. Implementation of a comprehensive cervical cancer screening programme carries important public health impacts, the coverage of which would directly influence the incidence rate of cervical cancer.
