Ans : 3 ( Park / Pg 244)

The most common route of transmission of leprosy has not been established with certainty. The following theories are frequently debated: (a) Droplet infection: There is more and more evidence that leprosy is transmitted via aerosols containing M. leprae (droplet infection). With the realization of the importance of the nose as a portal of exit, there has been increased emphasis of the respiratory tract as the portal of entry. (b) Contact transmission: Numerous studies indicate that leprosy is transmitted from person-to-person by close contact between an infectious patient and a healthy but susceptible person. This contact may be direct (e.g., skin-to-skin) or indirect (e.g., contact with soil, and fomites such as contaminated clothes and linen). Now that it is known that leprosy bacilli can survive for long periods of time in the soil under favorable environmental conditions, the hypothesis that leprosy can be transmitted by indirect contact has been strengthened. In epidemiological studies, the first lesions were found in feet and legs of patients from hilly areas in India where injury to the skin is common. In the Philippines 91 per cent of the first lesions were seen in extremities open to injury. These observations lend support to indirect transmission. Although contact transmission has been a long-favored hypothesis, leprologists opine that skin-to-skin contact is really not necessary to acquire infection, and that the disease is transmissible with far less than intimate contact (c) Other routes: Bacilli may also be transmitted via breast milk from lepromatous mothers, by insect vectors, or by tattooing needles. These transmission channels cannot be ruled out. However, there is no evidence that any of these transmission routes is important in nature. |
