The World health Organisation has announced it will need at least 1 billion US dollars (770,000 Euros) to contain the Ebola outbreak.<br /><br />The death toll in west Africa has doubled to almost 2,500 in the last month.<br /><br />WHO assistant director general Bruse Aylward said:“This health crisis we face is unparalleled in modern times. The numbers (of Ebola cases) can be kept in the tens of thousands, but that is going to require a much faster escalation of the response.”<br /><br />Meanwhile Ebola is having a devastating effect on tourism, a double blow to nations already battered by war and with fragile economies.<br /><br />However it’s not just countries with Ebola that are affected – tour operators from Kenya to South Africa say thousands of people from abroad are cancelling their holidays and business trips, fearful that the disease will spread across the continent.
