Nevertheless, amongst all of the unfavourable information about rising circumstances the world over, it was nice to listen to some excellent news about progress within the battle in opposition to one other lethal virus. With its elimination from Nigeria, Africa has lastly been declared free from wild polio by the World Well being Group.
Most individuals within the UK don’t know anybody who has survived polio but it surely was once one of many ailments mother and father most feared. It’s unfold by means of the ingestion of the virus from contact with an infectious particular person or from meals they’ve dealt with.
The overwhelming majority of affected youngsters have delicate or minimal signs, with it affecting the nervous system in lower than 1% of sufferers. Nevertheless, in these circumstances the end result could be devastating – leading to paralysis and even demise.
There have been 5 main epidemics within the UK between 1945 and 1960, with ‘paralytic polio’ affecting 3,000-7,000 individuals, largely youngsters, annually and inflicting 750 deaths.

Fortunately, there have been no new circumstances of untamed polio in Nigeria for 4 years and that is testomony to the work of GPEI and the dedication and persistence of its native workers.
By way of unprecedented international co-operation, the world has eradicated smallpox and is nicely on the way in which to eradicating the scourge of polio.
As with all vaccines, it’s essential to attain excessive charges of immunisation to forestall a return of the illness.
GPEI is now working extra intently with GAVI, the vaccine alliance, to make sure routine provision of the complete vary of childhood vaccines to each baby – no matter the place on the planet they reside. Whereas well being is threatened by the unfold of Covid-19, there may be additionally concern about its influence on routine vaccination programmes within the UK in addition to the world over.
Like Alexander Fleming, along with his discovery of penicillin, neither Jonas Salk nor Albert Sabin sought to patent their vaccines, so they’d be accessible the world over within the battle in opposition to polio. By way of unprecedented international co-operation, the world has eradicated smallpox and is nicely on the way in which to eradicating the scourge of polio.
