HONG KONG, China (Reuters) -- Syphilis, which was largely eliminated in China between 1960 and 1980, has returned with a vengeance and urgent intervention is needed to curb the epidemic, according to researchers in China and the United States.
In a study to be published in the January 13 issue of the Lancet, they said the total incidence of syphilis in China increased to 6.5 cases per 100,000 people in 1999 from less than 0.2 cases per 100,000 in 1993.

When the Communist Party took power in 1949, China was suffering one of the biggest syphilis epidemics in human history and the government launched a prolonged campaign to eliminate sexually transmitted diseases.
The study linked the re-emergence of syphilis to economic reforms and globalization in China.
