Leprosy is an age-old disease and is described in the literature of ancient civilizations. It is a chronic infectious disease which is caused bya type of bacteria called Mycobacterium leprae. The disease affects the skin, the peripheral nerves, mucosa of the upper respiratory tract, and the eyes. Leprosy is curable and treatment in the early stages...
Leprosy is a neglected tropical disease (NTD) which still occurs in more than 120 countries, with more than 200 000 new cases reported every year. Elimination of leprosy as a public health problem globally (defined as prevalence of less than 1 per 10 000 population) was achieved in 2000 (as per World Health Assembly resolution 44.9) and in most cou...
The disease is transmitted through droplets from the nose and mouth. Prolonged, close contact over months with someone with untreated leprosy is needed to catch the disease. The disease is not spread through casual contact with a person who has leprosy like shaking hands or hugging, sharing meals or sitting next to each other. Moreover, the patient...
The diagnosis of leprosy is done clinically. Laboratory-based services may be required in cases that are difficult to diagnose. The disease manifests commonly through skin lesion and peripheral nerve involvement. Leprosy is diagnosed by finding at least one of the following cardinal signs: (1) definite loss of sensation in a pale (hypopigmented) or...
Leprosy is a curable disease. The currently recommended treatment regimen consists of three drugs: dapsone, rifampicin and clofazimine. The combination is referred to as multi-drug therapy (MDT). The duration of treatment is six months for PB and 12 months for MB cases. MDT kills the pathogen and cures the patient. Early diagnosis and prompt treatm...
Case detection and treatment with MDT alone have proven insufficient to interrupt transmission. To boost the prevention of leprosy, with the consent of the index case, WHO recommends tracing household contacts along with neighbourhood and social contacts of each patient, accompanied by the administration of a single dose of rifampicin as preventive...
WHO provides technical support to Member States on leprosy prevention and control. Every year, WHO collates epidemiological data on leprosy from all its Member States and publishes a consolidated report in English and French in the Weekly Epidemiological Record, for data pertaining to the previous calendar year. These data are provided by countries...
Leprosy, also known as Hansen's disease ( HD ), is a long-term infection by the bacteria Mycobacterium leprae or Mycobacterium lepromatosis. [4] [7] Infection can lead to damage of the nerves, respiratory tract, skin, and eyes. [4] .

May 18, 2022 · Leprosy (also called Hansen’s disease) is an infectious disease caused by the bacteria Mycobacterium leprae (my-co-bak-TEER-ee-um LEP-pray). It can affect your eyes, skin, mucous membranes and nerves, causing disfiguring sores and nerve damage. Leprosy has been around since ancient times.
Mycobacterium leprae (also known as the leprosy bacillus or Hansen's bacillus) is one [a] of the two species of bacteria that cause Hansen's disease (leprosy), [1] a chronic but curable infectious disease that damages the peripheral nerves and targets the skin, eyes, nose, and muscles. [2]
Leprosy is a chronic infection usually caused by the acid-fast bacilli Mycobacterium leprae or the closely related organism M. lepromatosis. M. leprae was the only known cause of leprosy until 2008, when a second species, M. lepromatosis was identified in Mexico. Together, these two organisms are called M. leprae complex.
