UPDATES ON THE GWD CERTIFICATION EXERCISE IN NIGERIA
Guinea worm disease (GWD) is one of a group of diseases
classified as Neglected Tropical Diseases (NTD) because they are indeed
neglected so also are the poorest persons in the society who are most commonly afflicted
by the NTDs. GWD is caused by a parasitic nematode worm which emerges from the skin
after about one year following ingestion of water from unsafe, contaminated sources (usually
ponds).
Nigeria was the world’s most endemic country in the 1980s
with over 650,000 cases reported. The country however interrupted disease
transmission and reported its last case on the 11th of November 2008
as claimed in the Nigeria country report presented to the International
Certification Commission on Disease Eradication (ICCDE) of the WHO by the
Federal Ministry of Health.

Following the request of the Nigerian government to the
ICCDE to certify Nigeria free of Guinea worm disease having maintained zero
case status for GWD for five years, the ICCDE sent an International
Certification Team (ICT) to the country in June 2013 to validate the claim that
Nigeria had indeed interrupted transmission, and has a national disease
surveillance system that is sensitive enough to detect imported cases, or any
on-going local transmission of the disease.

The ICT in discharging this very important responsibility,
visited 17 states and the FCT, 60 LGAs, 136 villages and health facilities, and
interviewed 1360 persons in what the team leader; Prof. David Molyneux
described as, ‘a very large forensic exercise of significant public health importance’.
They examined the records and reports of diseases surveillance activities at
all levels of government, verified the existence of safe water sources, examined
and tested the public knowledge of GWD and the cash reward for reporting
suspected cases.

At the end of the three week exercise Prof David Molyneux debriefed the Hon. Minister of Health Prof. Onyebuchi Chukwu of their findings and made recommendation to the Government and people of Nigeria. He informed a very attentive Hon Minister that evidence found in the field showed that Nigeria Guinea worm eradication Programme had met the minimum required criteria for certification. His team found that there was no on-going transmission of GWD; there was a sensitive national surveillance system that could detect imported cases and any local transmission, especially with the complementary use of polio vaccinators for GWD case searches during national immunisation days; there was evidence of provision of portable water supply to rural communities at risk of the disease. Prof David Molyneux and his team were also impressed with the level of public knowledge of the GWD and the cash reward scheme for reporting a confirmed case.
The ICT team however reminded the Federal Ministry of Health
that his team can only make recommendations which are subject to the final
decision of the ICCDE and the Director General of the WHO in December 2013.
He also added that there is now the need for even further
strengthening of the surveillance system and cross border collaboration with
countries like Chad and Niger that are yet to be certified free of GWD. He
commended water providing agencies for the good work they had done but insisted
they needed to do more to ensure that such water sources are maintained to
continue to deliver safe water to the people. He also stressed the importance
of record-keeping , archiving and the need to ensure that publicity activities
through the print and electronic media continue. The need to also ensure that
all rumours of GWD must be investigated within 24 hours and properly
documented.
The Hon Minister thanked the ICT members and for the good
job they had done especially considering the size of the country , its
difficult terrain and the current security challenges in some States. He said
the ministry will immediately begin to implement the recommendations of the ICT
while the country awaits the official pronouncement from the ICCDE and the DG
WHO in December 2013.
End of year gift
On the 6th of December 2013, the WHO announced on its website that it had certified five countries as free of GWD. The list included
the world’s formerly most endemic country; Nigeria and its neighbour; Niger. Others
were Ivory Coast, South Africa and Somalia. Click here
This achievement is significant as the world again marches
closer to the eradication of another disease after small pox. It is also exciting
for the Nigeria NTD Programme which has by this WHO pronouncement achieved a milestone
set in its strategic NTD Master Plan.
This momentum will carry us into 2014; a year in which the
NTD programme plans to scale up ongoing intervention activities and conclude all epidemiological mapping to
determine disease prevalence.
