Do you think it will come to the UK
I don't think it's impossible for someone with the virus to arrive in the UK, require treatment or even die. I don't think it's impossible for there to be a UK person who contracts Ebola from within the UK from such a person. I don't think it's impossible that we may be, at some point, monitoring a handful of people to see if they develop the disease.
What I do think is so unlikely I don't waste time worrying about it is that Ebola in the UK will present any significant or serious threat to public health. It doesn't scare me that someone may come here with it and die, infect others or create a mini-pocket of infection, because I know how this virus spreads (with difficulty), I know how straightforward it is to contain (basic hygiene and quarantine rules apply), I know how easily it burns itself out (quickly).
I am a PhD biologist (albeit not anything infectious disease related). My husband is a PhD virologist. Neither of us are remotely concerned. I don't say that to command authority, but to say that people who perhaps have a better handle on what this is aren't actually worried (hopefully that doesn't sound patronising and you get my intention). In fact, we are both pretty furious at how this is being mishandled by the media.
