Ebola is not just a health crisis. It has unpicked the fabric of whole societies. Yet the devastation the disease has caused is still barely understood beyond the borders of Liberia, Sierra Leone and Guinea.
In Liberia, the worst-hit country, most hospitals are shut, all schools have been closed, businesses have shut up shop, and nearly a year's harvest has been lost.
The country's Information Minister said last month that Ebola could lead to the collapse of three whole states.
Yet the threat that Ebola poses to the United Kingdom, Europe and the United States and other developed countries, remains very low.
Despite the disproportionate amount of newspaper ink devoted to Western victims, we can be thankful that our 21st-century healthcare systems and infection control expertise mean we are fully equipped to quarantine any cases of a virus which can only be passed on through bodily fluids. We could nip an outbreak in the bud.
The catastrophe has exposed how vital modern health systems are. The speed with which the crisis has escalated is unprecedented.
An outbreak which began in a small Guinean village was able to spread, via the transport hub at Gueckedou, to neighbouring states. Our modern interconnectedness has enabled it to be carried by road to Senegal, and by aeroplane to Nigeria, 2600km away. But the disease has, thankfully, been contained in both of those countries.
Border checks, flight bans and public information: much has already been done to protect people outside a three-country area known as "the Ebola zone". Not nearly enough has yet been done to protect those within it.
Those people are at risk not only from Ebola, but from more common diseases - malaria, pneumonia, diarrhoea - which will run rampant because hospitals and clinics have shut down.
International efforts to save lives have increased. Three thousand US troops will soon be operating in the region, Cuba has sent hundreds of doctors, the UK has deployed engineers and NHS professionals.
All this will help. But what is needed is nothing short of the wholesale replacement of three entire healthcare systems. Only the military is capable of such a feat. Others should follow the US example.
Meanwhile the World Health Organisation has fast-tracked the testing and manufacture of two experimental vaccines, as well as experimental drugs. But vaccines will not reach the affected populations until the beginning of next year, and even then on a small scale. By that time there could be more than a million people infected.
