The « sleeping sickness song » Lékié area, Eton land, Centre-Cameroon. Sung in tehe 1950’s. Collected from Hubert Mvogo, nurse.

Translation The injection against sleeping sickness was too painful (bis) They gave me injection in the head They gave me injection in the neck They gave me injection in the back When they go down to give me injection in the bottom I want to go to the toilet
They ask me to go draw water from the well If I drag my feets The policemen hit me on the head The injection against sleeping sickness was too painful (bis)

Lesson 4 – pharmacology and public health policyMiracle drugs revisited: the case of Pentamidine-Lomidine
How did experts make sense of contradictions ? The drug which was too efficient
Failures and the indisciplined individual
Side-effects and African « pusillanimity »
The reference to the « race »
The case of Europeans : benefit/risk ratio
“these considerations [about accidents and cryptic infections] cannot lead us to hesitate to plan chemoprophylaxis campaigns in endemic regions as long as it is guaranteed that the campaigns can be continued until the end – because we consciously sacrifice individuals in front of the collective problem which has to be solved”.
Neujean, 1958, IBPTT report, Archives Africaines. Neujeans emphasis.
