Ebola virus is changing and becoming more dangerous

Vocabulary: to mutate (v), form (n), contagious (adj), blood sample (n), cure (v+n), vaccine (n), symptoms (n), to pass on (phrasal verb), to track (v), spread (n+v). Scientists who are studying the Ebola virus have said that it is mutating: the virus is changing its form. They are investigating whether the virus is more contagious than last year. Blood samples are being sent to France in order to study this. Ebola is a virus that is similar to HIV and Influenza (the flu): these types of viruses mutate rapidly; any cure or vaccine we have will not work on the new mutation. The fear is that Ebola has mutated so that some people who have the virus don’t show symptoms; they don’t look or feel ill at all. However, they are still contagious and pass the virus on to other people. Because they don’t show symptoms, it is more difficult to track the development and spread of the virus. Currently the survival rate of Ebola is 40%. The research in France will hopefully give scientists a clear reason as to why some people survive the virus and others don’t. They also hope to develop a vaccine against...

What is the future of Ebola?

vocabulary: to discuss (v), to be prepared for (v+adj), outbreak (n), vaccine, (n), epidemic (n), to come up with (phrasal verb), stable (adj). There has not been much about Ebola in the news recently. However, with the start of the World Economics Forum in Davos this week, many scientists and politicians are again starting to discuss Ebola. Ebola was discovered in 1976 but because very few people had had Ebola, there was no reason to spend lots of money researching it. Scientists believed that the disease was not very dangerous. This is why the world was not prepared for the outbreak of Ebola in western Africa last year. However, since last year, many trials have been organised to find a vaccine for Ebola. Professor Piot, from the London School of Tropical Medicine, said in Davos this week that the next time there is an epidemic of Ebola, there will be a cure. He also told politicians that countries must work together and come up with a global public health policy. He believes that there are likely to be more outbreaks of diseases like Ebola in the future. Because people travel more, and have contact with more people, this means that diseases can spread more quickly. The British nurse who returned to the UK with Ebola in December is in a stable condition and is recovering. She is still in hospital....

Ebola in the UK

Vocabulary: charity (n), to be diagnosed with (phrasal verb), symptom (n), to recover (v), to break out (phrasal verb) A British nurse has Ebola and is in the London Hospital. Ms Cafferkey was working in Sierra Leone with the charity Save the Children. She flew home from Sierra Leone in December and she was not ill when she arrived in the UK. She was checked in Sierra Leone and at Heathrow Airport for signs of Ebola. She was fine until she returned home to Glasgow, Scotland. It can take up to 21 days for a person to show symptoms that they have Ebola. Ms Cafferkey is the second person to have Ebola in the UK. In September another nurse, William Pooley, was diagnosed with Ebola. He recovered completely within a few days. Professor Hugh Pennington, an expert in Ebola, says that people respond to Ebola in different ways. Ebola has killed 7,800 people, mainly in West Africa since it broke out one year ago.
