The age of onset of leprosy.
The age of onset was determined in 1,053 consecutive patients having different types of leprosy. There were 675 males and 378 females. The majority had onset of the disease between ages 20 and 39, although all age groups were affected. The age of onset was significantly related to the type of leprosy; the mean was lowest in tuberculoid, highest in neuritic, while in borderline and lepromatous it was in between. The comparison of reports of the age of onset from India and elsewhere suggest that this varies in different regions with the country, and from country to country.
