The demystification of leprosy: a multifactorial problem.

Abolishment of misbeliefs and misconceptions, unfounded fear and prejudice are factors as important in leprosy control as prevention, early detection and therapy. Concrete measures of demystification are proposed. Identify and divulge the absolute truth about leprosy. Calling leprosy "Hansen's disease" did not result in demystification. Patients know that the two terms are identical. Treating them as human beings attracts more patients to the healers than the Hansenologian ritual. Contrary to statements, no major advances are being made in the field of bacteriology, immunology, molecular biology, mode of transmission and epidemiology of leprosy. Not a single new drug has been discovered in 26 years. Vaccination is a dubious venture. The question arises as to whether the right priorities are promoted in leprosy research. Cultivation of the leprosy bacillus is the sine qua non of any further progress. This field of research is a lost and totally neglected priority. Consequently we have no pharmacological model for badly needed of ultrapotent antileprosy drugs. Syphilis is now cured with a single dose of penicillin. A drug as potent against leprosy should not be a mission impossible if an appropriate pharmacological model--the in vitro culture--is available. The multifactorial problem of demystification is a difficult but not an impossible task. Less sensationalism, more real progress in research, selecting the right priorities, achieving the "ultimate drug", shelter, food, shoes, soap and broom for every human on this planet constitute the road to demystification.
