My hon. Friend is absolutely right to think about the implications further south. This outbreak is happening closer to the Ugandan border, but he is absolutely right that in due course it may be important to consider the impact on Burundi. He will be aware of the current very difficult situation for international non-governmental organisations in Burundi. Some NGOs have been asked to leave the country and the UK remains concerned about its ability to work with them there. However, I take on board his point that, should there be further movement to the south, it will be very important to ensure preparedness extends to Burundi.
