Polio is a highly infectious,
crippling and potentially fatal viral disease which mainly affects young
children. There is no cure, but there are effective vaccines. The strategy to
eradicate polio is based on preventing infection by immunising every child
until transmission stops and the world is polio-free. The source of polio
virus transmission is infectious humans spread mainly through the faecal-oral route
or, less frequently, by a common vehicle (e.g. contaminated water or food) and
multiplies in the intestine, from where it can invade the nervous system
and can cause paralysis. But, less than 1 in 200 infections leads to this. Of
those paralysed, 5% to 10% die when their breathing muscles become immobilised.

Johns Hopkins Bloomberg
School of Public Health is partnering with institutions in seven countries to
help document and disseminate knowledge from the polio programme. Reducing polio cases by 99.9%
globally is an incredible feat, achieved through innovative strategies and
years of trial and error. While the polio eradication programme is focused on
getting to zero, now is the time to make sure everything we’ve learned isn’t
lost and can be used to inform future global health programmes. Just as the
polio eradication effort applied lessons learned from the successful smallpox
campaign to its own work, the goal is for future health programmes to
understand and build on the knowledge of the polio effort. Under a new grant from the Bill & Melinda Gates
Foundation, the Johns Hopkins Bloomberg School of Public Health (JHSPH) will be
working to do exactly this.
will partner with academic institutions from around the world to document
lessons and develop graduate-level courses and hands-on training clinics for
public health students and professionals, including an online open course
available to the public and implementation courses for managers from other
health programmes. Under the leadership of Dr Olakunle Alonge, the team at
JHSPH will collaborate with a global team from public health institutions in
seven countries: , , ,
, the DRC, and . This will not only
ensure a balanced and diverse perspective, but also enable the exchange of
public health training strategies between the institutions. To develop the
content of each course, JHSPH will be identifying “change agents” at the local,
national and global levels who have expertise in polio eradication that may not
otherwise be captured. This unique global strategy promises to yield coursework
that speaks to the issues faced by a broad range of global health programmes
and actors. “Without an active strategy to map, package and deliver the
knowledge from the global polio eradication efforts to other programs and
global health actors, I’m afraid that these knowledge assets may not find any
useful purpose beyond the end of the polio campaign, which could come to an end
within a few years,” said Alonge. Alonge expects to glean lessons that will
apply to immunization systems, public health emergency response, primary health
care, disease eradication and infectious diseases—ensuring that the polio
programme continues to positively impact global health for years to come.
