Expat insurance customers may wish to have their children vaccinated against the human papillomavirus (HPV), as this has proven to be very successful in Australia.
During a BMJ Group podcast, director of the Melbourne Sexual Health Centre at the University of Melbourne Professor Christopher Fairley noted there has been an "absolutely dramatic decline" in the number of cases of HPV since the vaccine was introduced in the country four years ago.
Female school pupils and women aged under 27 can receive the inoculation and this has resulted in the number of young men with HPV falling from 23 per cent to three per cent, the professor stated.
Among women under 21, the proportion suffering from genital warts has declined from 19 per cent to two per cent, he declared.
Mr Fairley said: "Essentially, warts are disappearing in young heterosexuals in Australia now."
HPV is the most common sexually-transmitted infection and can affect the mouth and throat, as well as the sexual organs.
Although the majority of forms of this disease are not particularly dangerous, certain strains have been linked to cancers of the penis, anus, mouth, throat, vagina and vulva.
