Admittedly only what I have read in national newspapers - that Ebola is not contagious before the symptoms start showing and that it is not an air-bourne disease (like flu) but rather is spread through direct contact with bodily fluids.
National Geographic interviewed W. Ian Lipkin, an expert in viral diseases and the John Snow Professor of Epidemiology at the Mailman School of Public Health at Columbia University. Lipkin said the virus is not highly transmissable, but the number of people who can be infected by one person is high.
"You have to come into very close contact with blood, organs, or bodily fluids of infected animals, including people," he said.
Professor Peter Piot, who discovered Ebola, said to The Telegraph that a sense of panic and lack of trust in the West African authorities contributed to the outbreak. Piot said he would not be concerned about being in close proximity of an infected individual.
"I wouldn't be worried to sit next to someone with Ebola virus on the Tube as long as they don't vomit on you or something," Piot said. "This is an infection that requires very close contact." - www.syracuse.com/news/index.ssf/2014/08/ebola_important_facts_on_how_the_viral_disease_can_spread.html
It also seems to be widely agreed by the British media that if an infected person, or even a small number of infected people, were to arrive in the UK the NHS should be able to contain the disease and stop it spreading. Nationally we have a better understanding of good hygiene practice (soap and warm water kills the bacteria) and people have access to better healthcare here than they do in West Africa. In West Africa childbirth and diarrhoea are big killers but in most circumstances you would expect to survive those here because our healthcare system, whilst by no means perfect, is far far superior.
If the epidemic were in a country with comparable healthcare systems to the UK then I would be worried about it's spread here, but as it stands now the epidemic is in an area where, unfortunately, the healthcare people can expect to receive, and the cultural acceptance of Western medicine, is vastly different to here in the UK.
