Official
figures are yet to come out but health authorities are hopeful that the latest
mass polio immunisation campaign in Sierra Leone will break new grounds in
terms of coverage.
The exercise
which lasted from 24 to 27 March is this year’s second mass vaccination against
the virus that causes poliomyelitis [Polio], a debilitating disease that leads
to paralysis and deaths.
Children from
zero to 59 months were administered orally with the vaccine by volunteers who
moved door to door nationwide. A total of 1.5m children were targeted.
Polio mostly
affects children. The virus spreads through contacts from person to person, and
is contracted mainly via faecal route or orally. In less common ways it is
transmitted through food and water. The virus can invade an infected person’s
brain and spinal cord, in which case it causes paralysis within hours.
According to
WHO, 1 in 200 Polio infections leads to irreversible paralysis, and among those
paralysed, 5 percent to 10 percent die when their breathing muscles become
disabled. Symptoms include fever, headache, vomiting, and pain in the limbs.
Once a
person is infected with Polio, it is not curable. Therefore, the best way out
is prevention through vaccination.
When a child
is infected with the virus, it enters the body through the mouth and multiplies
in the intestine. It is then shed into the environment through their faeces
where it can spread rapidly, especially in situations of poor hygiene and
sanitation.
About 90
percent of infected people show no symptoms or very mild symptoms and this
makes it even easier for the virus to spread. But if enough people in a community
are immunised, the virus will be
deprived of vulnerable hosts and it will die out. High levels of vaccination coverage must therefore be maintained to ensure this. And the vaccine, given multiple times, can protect a child for life.
deprived of vulnerable hosts and it will die out. High levels of vaccination coverage must therefore be maintained to ensure this. And the vaccine, given multiple times, can protect a child for life.
Global efforts
The vaccine
is available via routine vaccination. In addition, every year the Ministry of
Health and its partners conduct several rounds of mass vaccination, in line
with the global Polio Eradication and Endgame Strategic Plan 2013-2018.
There exist
two main category of Polio virus – Wild Polio Virus (WPV) and Vaccine-derived
polioviruses. The latter is contracted from Oral Polio Vaccines, which rarely
happens. The WPV, which is the most common, is reclassified into types 1, 2 and
3.
WPV type 2 was
declared eradicated in 1999. Type 3 hasn’t been detected since November 2012, with
WHO concluding that the world may only have been dealing with type 1.
Nonetheless,
the Bivalent oral polio vaccine, which protects against both types 1 and 3, is
recommended for use.
Global
efforts to eradicate polio have been missed twice in the past - 2005, and 2010.
Nonetheless, huge progress has been made in terms of the reduction of cases by
over 99 percent since 1988, from an estimated 350, 000 cases to 74 reported
cases in 2015.
The WHO regions
of the Americas, Western Pacific, Europe, and South-East Asia have all been
declared free of polio. This means 80 percent of the world’s population now lives
in certified polio-free regions.
Nigeria,
Afganistan, and Pakistan are the three countries where Polio remains
persistent. A total of 36 cases were recorded in 2016 between these three
countries. In Nigeria, last month alone, three cases were recorded.
These
countries, dubbed the ‘Wild Polio Reservoir’, have one thing in common –
instability, fueled by religious and cultural factors.
Experts say
because of its highly infectious nature, as long as a single child remains
infected with the virus anywhere in the world, children in all countries are at
risk of contracting it. And WHO predicts that failure to stop polio in these
last remaining areas could result in as many as 200, 000 new cases every year,
within 10 years, all over the world.
The Nigerian
situation has held back the chance of Africa being declared Polio free. In the
meantime, the rest of the continent has the task of ensuring no new cases are
recorded, and that means high levels of consistent vaccination.
But even in
Sierra Leone cultural and religious factors are a concern.
Stumbling block
The Western
Area District Health Management Team (DHMT) had a coverage target of 95
percent, same as national target, ahead of this vaccination exercise. Thomas K.
Harding, District Social Mobilization coordinator, said figures obtained
administratively showed an impressive performance. But he noted that figures from
independent monitors, headed by WHO, will serve as official.
Harding told
Kombra Media Network (KMN) that feedback from this and previous exercises indicate
persistent resistance from the Lebanese and Fullah communities posing threat to
the national anti-Polio efforts.
“Over the
years these are the two people who have actually been the stumbling block to
our interventions,” he said, noting that refusal doesn’t only happen at
household level, but also at institutional level.
In order to
avoid any chance of a child missing out, the health ministry usually deploys
teams to schools and other institutions dealing with children. But school
authorities, under instruction from distrustful parents, deny access to the
volunteers.
Harding says
political intervention might be needed to address this culture of refusal.
A spokesman
for the Lebanese community denied knowledge of the campaign. Joseph Kudame,
Public Relations Officer of the body that represents the community in the
country, told KMN they were never involved and therefore were never aware of
the campaign. He however said they would be open to discuss with the
authorities.
Social mobilization
Another
obstacle to the mass immunization campaign is that many settlements in the
Western Area are located in hard-to-reach areas, so that volunteers are
reluctant to explore them.
New England
Ville, a mountainous settlement in the west end of Freetown, is a perfect
example of this. The largely deprived settlement shares borders with another community
with similar difficult geographical terrain – Dwarzak.
Melvin Tejan
Mansaray, journalist and community mobiliser in New England, says many of the residents
reported not seeing any volunteers during the last exercise, and he blamed that
on the apparent lack of involvement of community stakeholders.
Tejan’s
group, the New England Ville Community Development Organisation, uses town
criers to pass on information to people in areas only those who know the
community can reach. They were very useful during the Ebola epidemic. He says they
could have been useful to getting more people in their community immunized.
With support
from organizations like Unicef, a few local organizations have helped a great
deal in the social mobilization effort. One such group is Focus 1000, which operates
as an umbrella body of several grassroots national organizations, from market
women to religious leaders to traditional healers, and even journalists.
During this
campaign, representatives of these groups were deployed on the ground to help in
mobilisation and monitoring of the process.
Sheikh Hafiz
Sesay, National Chairman of the Traditional Healers Association of Sierra
Leone, was deployed in the Kalaba Town area in the east end of Freetown. He
observed that sensitisation wasn’t sufficient as people didn’t appear to know
about it exercise.
However, through
the Focus 1000 coalition, there has been a lot of improvement on social
mobilization, notably in the area of refusal on the basis of cultural and
religious grounds.
The Islamic
Action Group (ISLAG) has been notably instrumental in countering negative views
from within the mainly Muslim Fullah ethnic group. ISLAG, alongside the
Christian Action Group (CRISTAG), make up the influential religious arm of the
Focus 1000 family. Imams and Pastors use their pulpits in the mobilization
efforts.
Sheikh
Alhassan Kargbo, a senior member of ISLAG, said with their group being headed
by an influential Fullah scholar, Dr Ahmad Ramadan Jalloh, they have been able
to change a lot of the “wrong perceptions” among skeptics, using verses from the
vary Quran they use to justify their refusal.
“Islam doesn’t allow a Muslim to speculate about
things we have no knowledge about because they result to sin,” he says.
