MR. CATHCART WASON
I beg to ask the Under-Secretary of State for the Colonies if any steps are being taken in Uganda to prevent the spread of sleeping sickness by drawing cordons round infected districts, by destroying the breeding places of the particular fly that carries the disease, or especially by discouraging settlement round the lake or by stagnant water.
§ MR. CHURCHILL
The very full and careful investigations which, as the hon. Member is no doubt aware, are being conducted under the supervision of the Royal Society do not indicate that it will be practicable to prevent the spread of sleeping sickness by the methods referred to in the Question. The Secretary of State is advised that the only means of arresting the spread of the disease which would be practicable would be by the discovery of some treatment, curative or preventive, capable of being applied to man. This matter is now engaging the attention of the Tropical Diseases Committee of the Royal Society.
