Data on the rising incidence of @entity2953 and its relation to the use of modern contraceptives is reviewed. The World Health Organization (WHO) has estimated the existence of 100 million cases of @entity2954 annually in the world, and the disease is now the most common notifiable @entity281 after measles. WHO reported a worldwide 90% increase in syphilis since 1960, and @entity6369 (viral) has been reported as common as @entity2954 in England and Wales. Several studies indicate that sexual intercourse is initiated at a younger age and that premarital and extramarital sexual experience are increasing. Over 60% of @entity1 with @entity2954 have no symptoms; syphillis is milder in @entity1 than @entity1 , and nonspecific @entity790 are more difficult to detect in @entity1 . The mobile society promotes casual sex which favors the spread of @entity2953 . Although reliable evidence is scanty, oral contraceptives fail to provide a physical barrier and could thus facilitate transmission. A recent study of 522 @entity1 attending a @entity2953 clinic in Uppsala, Sweden showed that the number of partners and frequency of intercourse had increases for 141 @entity1 on the pill. @entity281 was common, and @entity2954 was diagnosed in 67% of 250 @entity1 . Evidence further suggests that the pill's alteration of the @entity413 metabolism changes in the genital tract resembling pregnancy may favor the growth of @entity365 . Evidence also indicates that IUDs may increase the incidence of @entity5280 , and the dangers of tubal blockage are likewise increased for the IUD user contracting @entity2954 . The condom remains the best protection against the spread of @entity2953 particularly if it is worn prior to intercourse and throughout intercourse.
