This article was originally published here on Thursday, November 27, 2014 under the heading "How world's worst Ebola outbreak began with one boy's death"
Emile Ouamouno was
just two years old and living in the remote Guinean village of Meliandou when
he began suffering from a fever, headache and bloody diarrhoea.
In December 2013,
despite his family's best efforts, the young boy died - followed within days by
his three-year-old sister Philomene and their pregnant mother Sia.
This was the start of
an Ebola outbreak so devastating that it would kill more than 5,000 people in a
year, leave hundreds of children orphaned and affect thousands more.
Virus smoulders undetected
The village of
Meliandou sits deep within the Guinean forest region, surrounded by towering
reeds and oil palm cultivations - these are believed to have attracted the
fruit bats carrying the virus passed onto Emile.
In a pattern that has
come to characterise the spread of this deadly virus as it tears into
close-knit communities, Ebola infected village health workers before spreading
to nearby districts.
But the first few
deaths failed to set off any alarm bells. Meliandou, located in Guinea's
Gueckedou province, is isolated. It is two hours to the nearest city on a
difficult road and people are accustomed to endemic diseases with early
symptoms mimicking those of Ebola.
Add to that a porous
land border, with many people regularly crossing into Liberia and Sierra Leone
in search of markets to sell their products, and the deadly virus was able to
smoulder undetected across unsuspecting communities for three months.
Early on, hospitals
quickly became Ebola incubators as health workers and doctors who believed they
were dealing with cholera or Lassa fever, a much less deadly haemorrhagic virus
prevalent in the region, fell ill after treating patients.
Of the first 15 deaths
documented in the New England Medical Journal tracing the current Ebola
outbreak, four were health staff.
How the outbreak started
'Transforming tradition into transmission'
As grieving relatives
gathered to bury their loved ones, one funeral turned into many.
Across the region, the
ritual preparation of bodies for burial involves washing, touching and kissing,
with funerals often attracting large numbers of mourners from nearby districts.
These rituals simply
helped the disease to spread.
US doctor William Fischer, who
worked in Guinea, said that by "transforming
tradition into transmission", Ebola managed to spread by attacking
the fabric of West African society.
Liberia: On the brink of collapse
Lack of resources have stymied the
battle to combat Ebola in Liberia, leaving the country teetering on the brink of collapse.
The first case across
the border was confirmed a few days after the World Health Organization (WHO)
officially declared the outbreak on 23 March.
But it was not until
August that the virus really took hold in the capital Monrovia, a densely
packed and notoriously poor city in the Montserrado district.
Throughout September,
the county was reporting more than 200 new cases each week.
Monrovia is home to
around a quarter of Liberia's total population. The majority of its residents
are crammed into rubbish-strewn slums, many of which are built on low-lying
swamps and are unconnected to a municipal sewage system.
Ravaged
by a 14-year violent civil conflict, that ended in 2003 and saw the near-total
destruction of its infrastructure, Liberia's health services struggled to
deliver basic services long before the Ebola outbreak.
With only around 60 Liberian doctors before the Ebola outbreak,
the death of a number of its high profile and most competent medical
professionals left the country's health staff decimated and demoralised.
Although
the infection rate has now declined, the country remains in a
precarious position.
Fear of Ebola still prevails and many of those infected continue
to stay home
"People
are hesitant and fearful as they don't know what happens in a treatment unit
and have heard lots of negative stories," says Darin Portnoy, a medical
doctor treating patients at a Medicines Sans Frontieres unit in Monrovia.
"That's where we lose the battle - when people hesitate to
come in. We can't get on top of the disease when people turn up four, five days
into their illness."
Liberia's health ministry has also urged people to stop burying
their loved ones secretly at night.
Even as knowledge of best practices to protect from the virus
infiltrates the entire region, this will perhaps be the hardest thing to stamp
out.
"To die of Ebola is one thing, but to be deprived of an
afterlife is quite another," writes Prof James Fairhead, an anthropologist
based at Sussex University and an expert on West Africa.
It was
one unsafe burial that ended up leading directly to Sierra Leone's explosion of
Ebola cases.
Sierra Leone: One funeral - 365 deaths
The country's first diagnosed case, when a pregnant woman was
admitted to a hospital in the Kenema district following a miscarriage on 24
May, infected no-one else.
Identifying the source of her infection, however, illustrates
how the virus entered the country.
The woman had attended the recent funeral of a well-known
traditional healer. The healer had treated Ebola patients flocking to seek her
care across the border from Guinea's Gueckedou region, before dying herself.
Health teams working in the region identified a further 13 women
who caught the virus attending the same burial, starting a chain reaction of
infections, deaths and more funerals.
According to the WHO, "quick
investigations by local health authorities suggested that participation in that
funeral could be linked to as many as 365 Ebola deaths".
From there Ebola spread to Sierra Leone's capital Freetown where
overcrowded living conditions and fluid population movements helped it to
spiral further out of control.
A
tragic footnote at the end of the study produced by doctors and scientists
tracing the outbreak into Sierra Leone highlights the ultimate price some
health workers have paid.
Five of the report's co-authors, including Sierra Leone's
leading physician spearheading the fight against haemorrhagic illnesses in West
Africa, contracted Ebola and died before the report was published.
Nigeria: A success story
The tale of another
act of true human sacrifice explains how Nigeria has managed to beat Ebola and
pull off what the WHO has called a "spectacular success story".
A country home to 170
million, Nigeria has almost seven times the combined population of Guinea,
Liberia and Sierra Leone.
A rapid response and
effective tracing of almost 1,000 individuals who may have been exposed to the
virus meant the number of Ebola deaths in Nigeria was limited to eight.
At the heart of the
fight against Ebola in Nigeria was Dr Ameyo Stella Adadevoh.
Dr Adadevoh diagnosed
American-Liberian Patrick Sawyer with Ebola when he was hospitalised in Lagos.
The doctor and her
staff physically intervened when Mr Sawyer tried to leave the treatment centre.
This action cost Dr Adadevoh and three medical staff their lives when they too
contracted the disease.
A New Phase
Almost
a year from two-year-old Emile's death, at least 5,500 people are estimated to
have died from Ebola.
Many more deaths have gone unrecorded.
Efforts to tackle Ebola have been hindered by fierce resistance
from local communities with a history of suspicion towards any outside
intervention.
This has enabled new chains of transmission to pop up and
threaten to spiral out of control.
Over
the last few weeks, health officials admit that the disease is now entering a
new phase, with a marked slowing down in the some of the affected areas in the
three countries, especially Guinea and Liberia.
But the battle is far from over, as WHO's Dr Christopher Dye
acknowledges.
"Even if we are able to say the exponential phase is over,
our goal is complete elimination in the human population and we clearly have a
long way to go on that."
