Large Ebola outbreaks new normal, said WHO

Large Ebola outbreaks new normal, said WHO

The world is entering ‘a new phase’ where large outbreaks of deadly diseases like Ebola are a ‘new normal’, the World Health Organization warned.

Previous Ebola outbreaks affected relatively small numbers of people, BBC reported.

But the Democratic Republic of Congo is dealing with the second ever largest outbreak, just three years after the world's largest outbreak ended.

The WHO said countries and other bodies needed to focus on preparing for new deadly epidemics.

There have been 2,025 cases of Ebola and 1,357 deaths from the virus during the outbreak in the Democratic Republic of Congo.

The largest outbreak, in West Africa in 2014-16 affected 28,616 people mostly in Guinea, Liberia and Sierra Leone. There were 11,310 deaths.

Yet the 12 outbreaks between 2000 and 2010 averaged fewer than 100 cases.

So why are modern outbreaks so much bigger?

"We are entering a very new phase of high impact epidemics and this isn't just Ebola," Dr Michael Ryan, the executive director of the WHO's health emergencies program told me.

He said the world is "seeing a very worrying convergence of risks" that are increasing the dangers of diseases including Ebola, cholera and yellow fever.

He said climate change, emerging diseases, exploitation of the rainforest, large and highly mobile populations, weak governments and conflict were making outbreaks more likely to occur and more likely to swell in size once they did.


'Get to grips'


Dr. Ryan said the World Health Organization was tracking 160 disease events around the world and nine were grade three emergencies (the WHO's highest emergency level).

He said, "I don't think we've ever had a situation where we're responding to so many emergencies at one time.

"This is a new normal, I don't expect the frequency of these events to reduce."

As a result, he argued that countries and other bodies needed to "get to grips with readiness [and] be ready for these epidemics".

The outbreak in DR Congo continues to worry health officials.

It took 224 days for the number of cases to reach 1,000, but just a further 71 days to reach 2,000.

Tackling the disease has been complicated by conflict in the region - between January and May there were more than 40 attacks on health facilities.

Another problem is distrust of healthcare workers with around a third of deaths being in the community. It means people are not seeking treatment and risk spreading the disease to neighbors and relatives.

Dr. Josie Golding, the epidemics lead at the Wellcome Trust, said the world needed to get better at preparing for such outbreaks.

She told the BBC, "With Ebola in West Africa, that was the mobility of people and porous borders — that is now the world we live in, that won't stop."

She said climate change could lead to more outbreaks like cholera in Mozambique after Cyclone Idai, but hoped diseases resulting from humanitarian crises would not be a new normal.

"Preparedness needs to be better, we can see movement of populations and climate change, a lot of this we can see coming, and we need more resources to plan and prepare."
