The world is still acting too slowly to stop Ebola
FOR months the world has sat largely idle 1 an Ebola epidemic has marched steadily from the remote jungles 2 Guinea to the slums 3 Liberia, and beyond. 4 September 16th that changed. Barack Obama announced the largest humanitarian deployment by America?s armed forces to fight an infectious disease. Saying that the epidemic “is not just a threat 5 regional security—it?s a potential threat 6 global security 7 these countries break down”, the president began
the process of sending some 3,000 American troops to set up treatment centers with 1,700 beds and to train local health workers.
The dispatch of troops to west Africa may seem an odd priority 8 American forces are preparing to confront jihadists in Iraq and Syria and are stretched thin elsewhere. Ebola is a disease that is usually absent 9 human populations, has been quickly stamped out in the past and in its worst recorded outbreak has thus far caused 3,000 known deaths (see article). Moreover it is unlikely to spread widely in rich countries 11 good health-care systems. Set 12 killers such as HIV, the virus that kills some 1.6m people a year, or tuberculosis (TB),which takes another 1.3m lives, an expensive fight against Ebola may seem a misallocation of resources.
Yet Ebola is now growing exponentially, 13 the number of new cases roughly doubling every three weeks or so. In Monrovia, the capital of Liberia, it is thought to be doubling every two weeks. Previous outbreaks were usually in rural villages 14 it was easier to contain. 15 this rate of progress, small numbers quickly become big ones, and there is a real risk 16 the disease spreading to cities such as Lagos, which is home 17 more than 10m people. The longer Ebola is allowed to replicate 18 humans, the greater the risk that it will become more contagious. Some virologists fret that it might even acquire the ability to be transmitted 19 the air 20 coughs and sneezes. Although this seems unlikely, nobody wants to find out just how quickly Ebola can adapt to humans.
Two things are urgently needed. The first is the rapid provision 21 basic protective gear such as gloves, gowns, surgical masks and disinfectant. Domestic health systems in affected countries have crumbled 22 nurses and doctors have fallen ill or died 23 lack of basic gear.
The second need is for trained staff to run the treatment centers and work in them. Poorly run ones 24 weak infection controls may hasten the spread of the disease. Both are needed soon, 25 the cost of halting Ebola?s spread is also rising exponentially. In August the World Health Organization estimated that it would take nine months and cost $490m to contain Ebola. Now it reckons the cost has risen to over $1 billion. The longer the world prevaricates, the harder and costlier it will be to contain this outbreak.
