I wouldn't be at all surprised if an individual with Ebola has already ended up in Rashid Hospital. With our diverse network, it is entirely possible that we have had a passenger on board with Ebola.
Along with the current very poor health of Khalifa, an Ebola case in Dubai would be one of the many 'sensitive' stories that the local media wouldn't dare to even think of reporting.
Back to the topic in hand. Sir TC stated on a recent Q&A session on ICE that there are 100 cities that he could rattle off as positively complimenting the EK network. Take 20 or so of those away due to bilateral 'tensions' and we probably have around 80 and to have 10 of those in Africa, seems highly plausible.
