Can some people's immune systems defeat Ebola virus before it has a chance to cause disease?

Africa's cities are melting pots of activity and interaction. There are fears that the continent's next major modern disease crisis will emerge from them.
Countries like Nigeria affected by Ebola have launched campaigns to curb the consumption of bushmeat like fruit bats.
Consuming bushmeat is thought to have contributed to the outbreak of Ebola in west Africa. Countries in the region are trying to slow down consumption.
Pregnant women in Sierra Leone, Guinea and Liberia were faced with the double fear of dying from Ebola as well during childbirth.
We found that less than 1% of published research papers around the time of both outbreaks, that related to the outbreaks, actually explored their gendered impact.

Increasing isolation threatens global health. International cooperation is critical to fighting diseases that will not respect borders.
Timeliness is important for detecting epidemics.
We need better surveillance systems to detect epidemics early. But while social media has been flagged as a potential solution, we're not quite there yet.

The fisheries sector in West Africa is beset with serious challenges including over-fishing and, in particular, illegal fishing.

Politics, not epidemiology or medicine, drives government responses to disease. Politicians are the ultimate decision-makers in public health, and they must respond to political forces.
GMOs may very well have filled up that syringe.

Public health experts enlist the molecular biology tools that create genetically modified organisms – as well as the GMOs themselves – in the fight against emerging infectious diseases.

Thousands of people acquire infections while hospitalized. Many are caused by urinary catheters, a routine part of a hospital stay. But cutting back on their usage can lower infection rates.
Now that UN peacekeepers have left Liberia, the country has much work to do.
There's no doubt it was time for the United Nations mission in Liberia to end. But there are some gaps in the country's plan to move on without the men and women in blue helmets.

They kill thousands of animals and people every year by spreading rabies. New research findings could solve the problem.
Academics have sent an open letter to the World Health Organisation calling for the Olympics to be postponed or moved because of the Zika threat. They're overreacting.

Understanding how the flu virus copies itself could open a way to killing it.
So much more can be achieved if African researchers work together.
There are a number of stumbling blocks to intra African collaboration. These must be addressed to ensure that research is not duplicated and that findings are shared.
Some 60% of bugs that infect humans originated in animals.
The world’s scientific community is focused on how to improve detection and responses to emerging diseases such as Zika virus and Ebola. So what can we learn from the most recent large-scale outbreaks?
Rabies rates are rising in Africa.
New initiative with old handsets halves rates of the disease in southern Tanzania – and is being applied to other conditions, too.

To tackle Zika and other viral outbreaks, we need to focus not only on the pathology of the disease, but also on the global political and economic architecture.
