I thank my right hon. Friend the Secretary of State and the Opposition spokesman, Dan Carden, for their very measured and detailed statements and replies. May I ask the Secretary of State about the situation in Goma? As far as we know, there are no cases in Goma at the moment, but it is a very large population centre. It seems, from the information I have, that it is not well prepared. Should the disease reach Goma, that could have extremely dangerous consequences. Goma is home to large numbers of refugees, as my hon. Friend John Howell pointed out.
