"Cheti cha daktari"
What do you call a doctor's certificate / medical certificate then? (A piece of paper a doctor gives you to prove, usually to your employer or school, that you are sick. It might not really be a thing in Tanzania and Kenya, I guess.)
Tried to find that in the "Swahili Medical dictionary and Phrasebook" . Didn't find it. It seems to be a useful book anyway, for those who have a special interest...
Cheti cha maumivu?? - sick note - but what would that mean in a Tanzanian context? Bush telegraph would deliver the information, anyway!
