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.
