The communist government under Mao Zedong, in response to the syphilis epidemic, issued free treatment for all those infected and increased screening for the disease. In the 1960s it was found that syphilis was almost completely eradicated in China Recent studies show evidence that the disease has seen a resurgence. In a study entitled "Syphilis in China: Results of a National Surveillance Program", researchers found that during 1993 the number of cases of reported syphilis was 0-2 per 100,000. During a national surveillance program in 2005 there were found to be 5-7 cases per 100,000 throughout the country. In that same study it showed that the city with the most prevalence of syphilis was Shanghai, with an estimated 55 patients with syphilis per 100,000 citizens. The second highest was Zhejiang, which had approximately 35 people with syphilis per 100,000; the third was Fujian, which had 28 patients per 100,000.
