The FOC give advice on how to keep safe if you decide to go to Egypt.
You should follow the regulations set by the local authorities and obey curfews. Make sure you keep valid photographic identification with you at all times.
If you are already in a part of Egypt where the FCO advise against all but essential travel, you should consider whether you have a pressing need to remain. If you decide to remain in Egypt, you should stay at or close to home or a place of safety (e.g. your hotel), keep a low profile and pay close attention to your personal safety, particularly in the larger cities. You should avoid crowds.
The Foreign and Commonwealth Office give this advice for anyone travelling to Egypt:
In view of continued unrest and the evolving political situation in Egypt, the FCO advise against all but essential travel to the rest of Egypt except for resorts on the Red Sea in South Sinai and those resorts on the Egyptian mainland in Red Sea governorate (including Hurghada).
