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.

人類乳頭瘤病毒(HPV)是一種經性行為傳播的常見病毒。其大部分感染不會引起病徵,但部分病毒類型會引致尖銳濕疣及增加患子宮頸癌機會。其中以16及18基因型的致病性風險至高。現今有疫苗能夠預防HPV感染:無論是兩價、四價或九價疫苗,均對16及18型發揮保護作用。新的九價疫苗更加能將保護伸展至另外七個HPV類型。

地圖顯示子宮頸癌於亞太地區的粗患病率及HPV16及18型的盛行率。南亞及東南亞地區皆錄得較高患病率。整體而言,16型於大部分國家的盛行率遠比18型為高。現時疫苗尚未在大部份國家普及使用,要有效預防子宮頸癌,接受定期篩查至為重要。推行全面子宮頸篩查計劃是具公共衛生價值的策略,其覆蓋率直接影響各地的子宮頸癌患病率。
