Last spring, most people would have guessed that this Ebola outbreak in West Africa would be over by the end of summer. Now, we're in the midst of the deadliest outbreak in history, which has lasted longer and spread further than anyone could have predicted.
The burden of the disease is in Sierra Leone, Guinea and Liberia right now. There have only been a handful of cases Nigeria, the most recent being a Lagos nurse who died after treating Nigeria's first Ebola victim, the Liberian-American Patrick Sawyer.
There are suspected satorini greece car rental Ebola cases in Europe , Asia , and North America but none are confirmed. Public health officials are relatively unconcerned about Ebola becoming a big problem in the developed world. That's because outbreaks persist in countries with poor sanitation and a shortage of resources to contain them, not in resource-rich places like the US.
For this reason, spread within satorini greece car rental Africa is really what public health officials are worried about. "Our first concern is that this is going to go into adjacent areas through people traveling in the region," said Daniel Bausch, associate professor satorini greece car rental at the Tulane University School of Public satorini greece car rental Health and Tropical Medicine, who is working with the WHO and MSF on the outbreak. "In the short term, the main vector is the traveler: local people traveling from one village to the next, on more regional scale, plane travellers."
This pie chart shows the final destinations satorini greece car rental of travellers originating in the three countries currently most affected satorini greece car rental by Ebola. satorini greece car rental As you can see, travel from Sierra Leone, Guinea and Liberia within the continent is much more prevalent than travel elsewhere.
To do this, contact tracing is essential, said Bausch. "With Ebola outbreaks, most of the time there's one or very few introductions of the virus from the wild into humans, and all the transmission after that is human-to-human transmission. So people who are traveling locally as well as on planes and other modes of transport, that's the way this would get around."
These efforts are already underway in Nigeria, where the disease hasn't yet turned into a full-scale outbreak but there are concerns that it might. Some 70 people who came into contact with a recently diagnosed Ebola doctor have been quarantined, said Dr. Ezie Patrick, the executive director for Africa with the World Medical Association who is based in Nigeria.
But resources to deal with more potential cases aren't presenting themselves, he added.  "In the current process, we don't have the facilities to isolate the patients," he said. When there's a suspected case of Ebola, it's reported to the Nigerian centers for disease control and they take over the case management. Patients often need to be moved from their homes to city centers. "When patients are moved from a rural to urban areas," Patrikck added, "the risk of spread increases exponentially."
"The worst-case scenario is that the disease will continue to bubble on, like a persistent bushfire, never quite doused out," said Derek Gatherer, a Lancaster University bioinformatician who has studied the evolution of this Ebola outbreak. "It may start to approach endemic status satorini greece car rental in some of the worst affected regions. This would have very debilitating effects on the economies of the affected countries and West Africa in general."
This dire situation could come about because of a "persistent failure of current efforts," he added. "Previous successful eradications of Ebola outbreaks have been via swamping the areas with medical staff and essentially cutting the transmission chains. Doing that here is going to be very difficult satorini greece car rental and expensive. We have little option satorini greece car rental other than to pump in resources and engage with the problem using the tried-and-tested strategy—but on a scale previously unused."
Resources are already  extremely constrained in most of the countries affected right now. As Dr. Bausch said, "If you're in a hospital in Sierra Leone or Guinea, it might not be unusual to say, 'I need gloves to examine this patient,' and have someone tell you, 'We don't have gloves in the hospital today,' satorini greece car rental or 'We're out of clean needles,' — all the sorts of things you need to protect against Ebola."
When Bausch was in Sierra Leone last month, he said all the nurses went on strike in one of the hospitals where he was working. "There satorini greece car rental were 55 people in the Ebola ward," he said, "and myself and one other doctor."
He'd walk into the hospital in the morning and find patients on the floor in pools of vomit, blood, and stool. They had fallen out of their beds during the night, and they were delirious. "What should happen is that a nursing staff or sanitation officer would come and decontaminate the area," he said. "But when you don't have that support, obviously it gets more dangerous." So the disease spreads.
