Polio persists in certain regions of the world

For almost four decades. In addition, the World Health Organization and its partners have been working to eradicate polio.

Although the number of cases has decreased by more than 99 %. Nevertheless, infectious and acute disease remains present in certain regions of Afghanistan and Pakistan. Moreover, Among the brakes on this eradication of cultural barriers, disinformation on vaccines and poverty.

I think this if you observe in Pakistan. Nevertheless, Afghanistan, the persistence of polio despite programs, it is simply because they have not reached the expected levels to eradicate the disease. Meanwhile, And the challenges are enormous. whether security problems, the lack of health care or social services in certain communities that have been affected for a long time, or the polio fight program, which has experienced ups and downs and does not necessarily benefit from rigorous management required, explains the Dr polio persists certain regions world Tom Frieden, of the independent surveillance committee for the eradication of polio:

According to experts, with the exception of Afghanistan and Pakistan, most cases of polio in the world are linked to the oral antipolio vaccine which contains a virus and can cause paralysis. Several hundred cases have been reported each year since 2021, including at least 98 this year.

In Africa. we have a polio derived from a vaccine strain which is in fact back what we call wild type polio and which causes the same paralysis as other types of polio. The good news is that we have a safer vaccine. It is currently deployed throughout Africa and has less risk of causing these cases. It is very important to understand that if vaccination programs are optimally carried out. there will be no polio derived from a vaccine strain. It is only when vaccines are not well used, polio persists certain regions world when there is too low coverage, that it can happen. And if the response to this problem is slow. as happened in Nigeria and in other countries, this new virus is installed and becomes more difficult to eliminate.

Most experts agree that the oral antipolio vaccine should be removed from the market as soon as possible. But they recognize that there are not enough injectable vaccines that do not use living viruses. do not present the risks of the oral vaccine to eliminate poliomyelitis alone.
