Left untreated, it has a mortality rate of 8% to 58%, with a greater death rate among males. [3] The symptoms of syphilis have become less severe over the 19th and 20th centuries, in part due to widespread availability of effective treatment, and partly due to virulence of the bacteria. [23] With early treatment, few complications result. [22]

[3] [6] Untreated, it has a mortality rate of 8% to 58%, with a greater death rate in males. [6]
According to a report from the Centers for Disease Control and Prevention on April 11, 2023, syphilis is now at a rate not seen since the 1950s, increasing by about 30 percent between 2020 and 2021, a big jump from syphilis rates recorded in the early 2000s, where only about 30,000 cases were recorded each year.

Some taught that the affliction could best be cured by a sweat bath followed by a rapid plunge into cold water. [58] [59] Furthermore the vaccines often lost their potency when transported and stored over long distances with primitive storage facilities. It was too little and too late to avoid the great smallpox epidemic of 1837 to 1840 that ...
Through intentional exposure to gonorrhea, syphilis, and chancroid, a total of 1,308 people were involved in the experiments. Of that group, with an age range of 10–72, 678 individuals (52%) can be said to have received a form of treatment. [9] However, Cutler claimed all had been treated.
