HC Deb 23 March 1970 vol 798 c274W
Captain Kerby

asked the Secretary of State for Social Services if, in view of the fact that the incubation period for leprosy is three to five years, he will estimate the number of new leprosy cases which will be notified in the United Kingdom by March, 1975.

Dr. John Dunwoody

It is impossible to make such an estimate.
