I agree with McGrath, it is uncertain. I have been merely extrapolating all this time -- as has everyone. There was a UNICEF report (forget which one) which seemed to be done carefully early on with reports from doctors and nurses who at that time still had a functioning clinic system and so on (one of the problems is that child mortality figures are very difficult to assess if your medical system is broken -- children die of dysentery, complications, etc. at home. Unless children are being taken regularly to clinics, and so on, the numbers are guesswork.
