Have you noticed that the deadly disease Ebola is no longer in the news? This started to cease to be newsworthy around Christmas last year. I guess the BBC decided there were more important issues like Nigel Farage, he says with a great deal of sarcasm.
The disease is still present in some West African nations but others have reported no new cases in some time now. I think the world was late to "wake up" to the real dangers of this condition. Luckily, it managed to be contained in West Africa, in the main. It could have spread so easily to western nations and been a real public health catastrophe.
