Large Ebola Outbreaks New Normal, Says WHO

Large Ebola outbreaks

The world is entering “a new phase” where big outbreaks of deadly diseases like Ebola are a “new normal”, the World Health Organization has warned.

Previous Ebola outbreaks affected relatively small numbers of people.

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

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

What is Ebola?

  • Ebola is a virus that initially causes sudden fever, intense weakness, muscle pain and a sore throat.
  • It progresses to vomiting, diarrhoea and both internal and external bleeding.
  • People are infected when they have direct contact through broken skin, or the mouth and nose, with the blood, vomit, faeces or bodily fluids of someone with Ebola.
  • Patients tend to die from dehydration and multiple organ failure.

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

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

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).

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 about a third of deaths being in the community. It means people are not seeking treatment and risk spreading the disease to neighbours and relatives.

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

“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, she said. But she 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.”
