Scientist who first discovered Ebola discusses the magnitude of the outbreak and Western 'hysteria' about the crisis.
In recent months the media has been awash with haunting pictures of suffering patients and the health workers who cannot save them - cannot even touch them - for risk of contracting a virus which has caused fear, panic and stigma.
Since the world's worst Ebola outbreak began in Guinea almost a year ago, it has killed more than 6,000 people and continues to spread. In some areas, the fatality rate is as high as 90 percent. Most cases are in West Africa, but there has been diagnosis of a patient in Spain and several others in the US.
However, this virus is not a new discovery. Back in 1976 scientists first came across a mysterious disease in the Democratic Republic of Congo and named it Ebola after a nearby river.
"It took a thousand dead Africans and two Americans who were repatriated to the US because they were infected. There's no excuse for that ... it took too long, we wasted too much precious time," he says.
He talks about what he calls an epidemic of 'hysteria' in the US and the UK's reactions to the outbreak.
"There is an epidemic of Ebola in West Africa and then there is a second epidemic, an epidemic of mass hysteria that we saw particularly in North America. And it was really out of proportion with the issue," he says.
"Of course, people have become infected, one nurse has become infected in Texas, but you know putting people in quarantine who return from West Africa for 21 days - as some US states are imposing - doesn't make sense from a public health perspective, it's not cost effective and also it's a major deterrent and disincentive for supporting the countries in West Africa."
Piot says the most effective way to stop the epidemic is to address the lack of robust healthcare systems in many West African countries, and also deal with local cultural practices and belief systems, such as ideas of 'witchcraft' and the habit of touching the dead at funerals.
But progress is being made. According to the WHO, 70 percent of all funerals are now conducted in a safe manner. And 70 percent of all patients are isolated and treated. But before this ends, these numbers must reach 100 percent.
Meanwhile, pharmaceutical companies are racing to find both vaccines and effective treatments.
So, nearly four decades after Ebola was first discovered, why is there still no cure? Should experimental drugs be tested on patients in Africa? And why was the world so slow to realise the enormity of the crisis?
Today on Talk to Al Jazeera, Felicity Barr sits down with microbilogist Peter Piot.
