A child in Kano, northwest Nigeria receives the vaccine in 2017 |
The World
Health Organization (WHO) is set to certify on Tuesday that the African
continent is free from wild polio, four years after the last cases appeared in
northeastern Nigeria.
"Thanks
to the relentless efforts by governments, donors, frontline health workers and
communities, up to 1.8 million children have been saved from the crippling
life-long paralysis," the WHO said in a statement.
The
official announcement is due at 1500 GMT in a videoconference with WHO
director-general Tedros Adhanom Ghebreyesus and key figures including
philanthropist and Microsoft founder Bill Gates.
"Happiness
is an understatement. We've been on this marathon for over 30 years," said
Tunji Funsho, a Nigerian doctor and local anti-polio coordinator for Rotary
International.
He said it
marked a crucial step in the total eradication of the illness at the global
level.
"It's
a real achievement, I feel joy and relief at the same time," he added.
Poliomyelitis,
or "wild polio" is an acutely infectious and contagious disease which
attacks the spinal cord and causes irreversible paralysis in children.
It was
endemic around the world until a vaccine was found in the 1950s, though this
remained out of reach for many poorer countries in Asia and Africa.
As late as
1988, the WHO counted 350,000 cases globally, and in 1996 said there were more
than 70,000 cases in Africa alone.
Thanks to a
rare instance of collective global effort and financial backing -- some $19
billion over 30 years -- only Afghanistan and Pakistan have recorded cases this
year: 87 in total.
Trust
Nigeria, a
country with 200 million inhabitants, was still among the trouble-spots in the
early 2000s.
In its
northern Muslim-majority areas, authorities were forced to stop vaccination
campaigns in 2003 and 2004 by Islamic extremists who claimed it was a vast
conspiracy to sterilise young Muslims.
It took a
huge effort in tandem with traditional chiefs and religious leaders to convince
populations that the vaccine was safe.
"People
trust their local traditional leaders who live with them more than the
political leaders," said Grema Mundube, a community leader in the town of
Monguno, in the far north of Nigeria.
"Once
we spoke to them and they saw us immunising our children they gradually
accepted the vaccine," he told AFP.
However,
the emergence of violent Islamist group Boko Haram in 2009 caused another
rupture in the programme. In 2016, four new cases were discovered in Borno
state in the northeast in the heart of the conflict.
"At
the time, we couldn't reach two-thirds of the children of Borno state --
400,000 children couldn't access the vaccine," said Dr Funsho.
Inaccessible children
The
security situation remains highly volatile in the region, with the jihadists of
Boko Haram and a local Islamic State affiliate controlling vast areas around
Lake Chad and the border with Niger.
"International
agencies, local governments, donors -- all partners took the bull by the horns
to find new strategies to manage to reach these children," said Dr Musa
Idowu Audu, coordinator for the WHO in Borno.
In these
"partially accessible" areas, vaccination teams worked under the
protection of the Nigerian army and local self-defence militias.
For areas
fully controlled by the jihadists, the WHO and its partners sought to intercept
people coming in and out along market and transport routes in a bid to spread
medical information and recruit "health informants" who could tell
them about any polio cases.
"We
built a pact of trust with these populations, for instance by giving them free
medical supplies," said Dr Audu.
Today, it
is estimated that only 30,000 children are still "inaccessible": a
number considered too low by scientists to allow for an epidemic to break out.
Despite the
"extreme happiness and pride" felt by Dr Audu, he never fails to
remember the 20 or more medical staff and volunteers killed for the cause in
northeast Nigeria in recent years.
The
challenge now is to ensure that no new polio cases arrive from Afghanistan or
Pakistan and that vaccinations continue to ensure that children across the
continent are protected from this vicious disease.
"Before
we couldn't sleep at all. Now we will sleep with one eye open," said Dr
Funsho.
