The good news today is that the nurse in the UK is slowly improving and is no longer described as "critical". I do hope her recovery continues and she gets back to full health very soon. She must have been very frightened but at the same time she knew her treatment in the UK would be better than she would have had in West Africa.
There are slight signs that the disease has peaked and an end to the West African outbreak may be in sight. It will be many months before we can be sure.
