Please be advised that Nairobi like any other large city has a security and crime problem. However , if you observe the following simple guidelines you will stay and have a trouble-free seminar（研讨会）：
1．Do not wear a money belt. This makes you an instant target.
2．Cameras of all kinds are a favourite with snatchers. Feel free to use them within the Starehe Campus and the hotel grounds but not in the streets.
3．Ladies handbags are also a regular snatch. Avoid carrying one ,and if you must ,be
careful and hold on to it tightly.
4．Jewellery and even glasses with valuable frames are also often targeted .Bear this in mind.
5．When in a vehicle keep the doors always locked. And the windows only slightly open ,especially at traffic lights ,junctions and in slow moving traffic.
6．Beware of street children ,their begging often quickly changed into something more unpleasant.
7．Stay with the main party all the time ,and avoid wandering off on your own.
8．Finnally , the best defence is to be careful at all times and conscious of your environment.
