[The campaign against sexually transmissible diseases and endemic treponematoses].

From the moment WHO was established in 1948, the control of venereal diseases was felt to deserve highest priority, together with activities to control malaria and tuberculosis. International action was needed in view of the high morbidity and mortality from venereal diseases, their serious human and social consequences, and the prevalence of congenital syphilis and other sexually transmitted diseases (gonorrhoea, chancroid, venereal lymphogranulomatosis, granuloma inguinale). WHO immediately set up a global programme for the control of STDs and, with the participation of other agencies, especially UNICEF, furnished countries with assistance in the form of personnel, equipment and funds for the operation of programmes to assess the extent and impact of STDs and to plan and implement practical measure of control. The 1950s witnessed a steady and considerable decline in syphilis and gonorrhoea and many health authorities relaxed their control activities and efforts to maintain public awareness of the problem. In contrast to the prevailing optimism, WHO repeatedly stressed the possibility of a renewed upsurge of STDs. In the 1960s and 1970s, there was a sharp rise in STDs, both in the "classic" diseases (the five venereal diseases mentioned above) and also in the "second generation" STDs (chlamydial infection, genital herpes, human papillomavirus and other infections). Through its programme for the control of STDs, WHO put forward suitably designed control strategies, essentially based on information and education for health, screening for STDs, diagnosis and treatment of cases, contact tracing, and the training of health personnel. By the end of the 1970s, the bacterial, but not the viral STDs, had been contained in the industrialized countries. In many of the developing countries, STDs remained a priority public health problem, above all on account of the seriousness of their sequelae. In 1981, a new sexually transmitted disease-the acquired immunodeficiency syndrome (AIDS)-was identified. As of 1982, the WHO Programme on STDs organized meetings to define the extent of the problem, compare experience, promote and coordinate research and propose strategies for prevention. In 1987, WHO established a Global Programme on AIDS. It is clear that the control of STDs is now more than ever a priority. We have strategies for the prevention and control of STDs and the WHO Programme will continue to collaborate closely with countries in strengthening their national control programmes.(ABSTRACT TRUNCATED AT 400 WORDS)
