The name "the clap", in reference to the disease, is recorded as early as the sixteenth century, referring to a medieval red-light district in Paris, Les Clapiers. Translating to "The rabbit holes", it was so named for the small huts in which prostitutes worked.In 1854, Dr. Wilhelm Gollmann addressed gonorrhea in his book, Homeopathic Guide to all Diseases Urinary and Sexual Organs. He noted that the disease was common in prostitutes and homosexuals in large cities. Gollmann recommended the following as cures: aconite to cure "shooting pains with soreness and inflammation;" mercury "for stitching pain with purulent discharge;" nux vomica and sulphur "when the symptoms are complicated with hemorrhoids and stricture of the rectum. Other remedies include argentum, aurum (gold), belladonna, calcarea, ignatia, phosphorus, and sepia.Silver nitrate was one of the widely used drugs in the 19th century. However, it became replaced by Protargol. Arthur Eichengrün invented this type of colloidal silver, which was marketed by Bayer from 1897 onward. The silver-based treatment was used until the first antibiotics came into use in the 1940s.The exact time of onset of gonorrhea as prevalent disease or epidemic cannot be accurately determined from the historical record. One of the first reliable notations occurs in the Acts of the (English) Parliament. In 1161, this body passed a law to reduce the spread of "... the perilous infirmity of burning". The symptoms described are consistent with, but not diagnostic of, gonorrhea. A similar decree was passed by Louis IX in France in 1256, replacing regulation with banishment.
Similar symptoms were noted at the siege of Acre by Crusaders. Coincidental to, or dependent on, the appearance of a gonorrhea epidemic, several changes occurred in European medieval society. Cities hired public health doctors to treat affected patients without right of refusal. Pope Boniface rescinded the requirement that physicians complete studies for the lower orders of the Catholic priesthood.Medieval public health physicians in the employ of their cities were required to treat prostitutes infected with the "burning", as well as lepers and other epidemic patients. After Pope Boniface completely secularized the practice of medicine, physicians were more willing to treat a sexually transmitted disease. Research
A vaccine for gonorrhea has been developed that is effective in mice. It will not be available for human use until further studies have demonstrated that it is both safe and effective in the human population. Development of a vaccine has been complicated by the ongoing evolution of resistant strains and antigenic variation (the ability of N. gonorrhoeae to disguise itself with different surface markers to evade the immune system).As N. gonorrhoeae is closely related to N. meningitidis and they have 80–90% homology in their genetic sequences some cross-protection by meningococcal vaccines is plausible. A study published in 2017 showed that MeNZB group B meningococcal vaccine provided a partial protection against gonorrhea. The vaccine efficiency was calculated to be 31%. References
