I agree completely tuk tuk. The WHO does not need ratings. Obviously Bristow and other companies will try to play this down and compare Ebola to a common flu outbrake, but Ebola is deadly. Yes there are many risks down there, a long list, but Ebola is the latest, very deadly, and it is very disappointing to see that Bristow (as with all other potential problems affecting staff) just dont care at all. Their response has simply been: wash your hands, look out for ill people and if you don't like it you know where the door is...
