Chemoprophylaxis and gonococcal infections in prostitutes.

The influence of chemoprophylaxis on gonorrhoea has not been reported recently. 777 prostitutes were interviewed and checked for evidence of chemoprophylaxis. The study showed that chemoprophylaxis does reduce the risk of gonococcal infections and that those who took penicillin chemoprophylaxis had a higher risk of Penicillinase producing Neisseria gonorrhoeae (PPNG) infections compared to those who took non-penicillin chemoprophylaxis and those who did not take any prophylaxis.
