This is important because it helps in selecting the correct combination of drugs regimen for a given person.Table KDT 7th784: National Leprosy Eradication Pro- gramme2009 Classification of leprosyPauclbacillaryPBMultibaciliary MB 1-5 skin lesions Ho nerveonly one nerve involvement -1-5 skin lesions Skin smear negative at all sites 6 or more skin lesions 1 nerve involved irrespective of number of skin lesions Skin smear positive at any one siteNote: if skin smear is positive irrespective of number of skin and nerve lesions, the disease is classified as MB leprosy but if skin smear is negative it is classified on the basis of the number of skin and nerve lesions.Regular treatment: A patient may be considered to have regular treatment if heshe has received MDT for atleast two-thirds of the months in any interval of time. E.g regular treatment for 12 months, implies that the patient has had at least 8 full months of combined therapy during the 12-month period- Park21st296LEPROSY OR HANSEN S DISEASE OR SOCIAL DISEASE: SHORT REVIEW Leprosy is not particularly a disease of children as was once believed. However, the presence of leprosy in child population is of considerable epidemiological importance. A high prevalence of infection among children13 means that the disease is active spreading- Park20th278Lepra bacilli can survive for long periods of time in soiP under favourable environmental conditions. There is now evidence that natural infection with M. leprae are present in wild animals e.g. armadillos,, mangabey monkeys chimpanzeesThe tuberculoid type of lesions are bacteriological!- negatives The role of inviduals with tuberculoid forms of the disease as sources of infection is not yet clear.Bacilli may also be transmitted by insect vectorsQ or by tattoing needles. However, there is no evidence that any of these transmission route is important in nature- Park 20th279Relapse ratef is one of the best indicators of the efficacy of the drug regimenQtr- Park 20thf288The bacterial load is the highest in the lepromatousf casesLeprosy is a highly infections disease but of low pathogenicityBoth the incidence prevalence of leprosy appear to be higher in males1 than in femalesLeprosy may be transmitted via aerosols containing M.leprae droplet infection1Bacterial index BI is the only objective way of monitoring the benefit of treatment.The most commonly affected nerve are the ulnad3, posterior auricular, peroneal posterior tibial nerves- H171022The histamine test is a very reliable method for detecting at an early stage peripheral nerve damage due to leprosy-park 20th281During the course of leprosy, immunologically mediated episodes of acute or subacute inflammation known as lepra reaction may occur. Because peripheral nerve trunks are often involved, unless reaction are promptly adequately treated, such episode can result in permanent deformities- Park21st297Immunoprophylaxis: Trial in different population group with BCG vaccine either alone or in combination with other vaccines from killed mucobacterium leprae or atypical mucobacterium, have shown protective efficacy ranging bfw 28 60. High BCG coverage remains an important contribution to reducing the disease burden due to leprosy- Park 21st292
