Community engagement (click here) is key to successfully controlling outbreaks. Good outbreak control relies on applying a package of interventions, namely case management, surveillance and contact tracing, a good laboratory service, safe burials and social mobilisation.

Early supportive care with rehydration, symptomatic treatment improves survival. There is as yet no licensed treatment proven to neutralise the virus but a range of blood, immunological and drug therapies are under development.

One thing I said early on was that the 'condition' of the patient was vital to fight this disease. I stated the reason so many succumb to this virus is due to the fact they have poor health to begin with. No one should be proud of the fact Americans may fair better than Africans, but, it is a reasonable belief about the outcomes regarding this virus. 

There have been people that have survived in Africa. The difference might be more socio-economic than disease related. There should be some kind of record reflecting the success of the survivors and why they edged out over the progress of the disease.

In patients with poor health on admission to any hospital anywhere may need more than simply fluids, they may need intravenous nutrition as well. The idea is to maintain and/or improve the wellness of the person while the disease progresses and ultimately end due to acquired immunity in the body's fight against the virus.

There can also be secondary bacterial and/or viral infections that occur when a human body depletes it's 'wellness reserves." That also has to be treated until the virus runs it's course. The survivors have a course that was successful, the question is what were the components to their survival.
