TitleCopy letter from Michael Foster, to the Under Secretary for Foreign Affairs, Foreign Office, S.W.
Date9 November 1903
DescriptionOn 27 January the Under Secretary addressed a letter to the Royal Society asking if in the opinion of its Committee, there was any danger of Sleeping Sickness being introduced into South Africa if natives were allowed to emigrate from the Protectorate to serve as labourers in the Colony. Explains why he replied that this is free from serious risks.

Since that date knowledge of the subject has made considerable advance and they have weighty evidence that Sleeping Sickness is a disease very analogous to Nagana or Tsetse Fly disease in animals, due to a parasite introduced into the blood by a biting fly. Sleeping Sickness is not a contagious or infectious disease conveyed direct from subject to subject. From this they can infer that natives taken from an infected area, to another previously uninfected area would not spread the disease, unless the carrying fly, Glossina palpalis is present, or unless it is found that some other agent besides Glossina is able to carry the parasite from subject to subject.
