Somalia: I was a student in those days and not working in the system at that time, so I don't know exactly what took place. From what I have read, screenings weren't done in that sense. There wasn't a check, a questionnaire that was filled out by serving members, but the expectation would have been that people would have had their medical file annotated or the pharmacy record on them would have been kept.
It's difficult at this point to look back at that, because pharmacy records are required to be kept for two years, so some of these records have been lost, not due to malice, but in the normal process of maintaining records.
