Will leprosy spread within a family?

Hi,

Welcome to icliniq.com.

I want to share few facts about leprosy. Leprosyis contagious, because Mycobacterium leprae is transmitted from one person to another by droplet infection through nasal or respiratory mucosa or by direct contact in susceptible persons. All persons exposed to this disease do not develop it. Specific deficiency in the cell-mediated immunity of the host towards the Mycobacterium leprae plays an important role in acquiring this infection. Overcrowding, poor hygiene and inadequate housing favor the transmission of the disease by causing more intimate contact. If your family member has BL (borderline lepromatous leprosy) or LL (lepromatous leprosy) type of leprosy, then chances of getting leprosy by contact are much higher than TT (tuberculoid leprosy) or BT type (borderline tuberculoid leprosy). You should get slit skin smears for AFB - acid fast bacilli. Also check for the signs below.

1. Hypoesthetic skin lesions (numb patch).
2. Thickened peripheral nerves - cord like painful structure of your limb.
3. Demonstration of AFB.

If any two of the above or a positive histopathological picture confirms the diagnosis, then you should start multidrug therapy.
