Pakistan has made a lot of progress this year in wiping out polio. There are signs that one type of poliovirus is gone and transmission of other strains seems to be slowing.
But a recent outbreak of polio there has health officials concerned about the overall effectiveness of the effort to eliminate polio in that country.
The World Health Organization says 10 cases of so-called vaccine-derived polio were reported in Pakistan between the end of August and the end of October.
What's that? The oral polio vaccine contains a weakened version of the virus. In very rare instances and when a population isn't well immunized the weakened virus can circulate in the community, mutate and infect unvaccinated people, causing paralysis. This is known as a vaccine-derived polio.
Fully immunized kids are protected against both vaccine-derived and wild polio. So the problem isn't so much with the vaccine as it is with gaps in immunization.
This is the first time that vaccine-derived polio has been detected in Pakistan. The cases appeared in the north of the Balochistan province near the Afghan border.
WHO officials say the outbreak, involving a variety of the virus called type 2 polio, illustrates that vaccination campaigns in the area are failing to reach sufficient numbers of people.
Wild strains of type 2 polio were eradicated globally in 1999. However, a new strain of vaccine-derived polio emerged because the vaccine continued to contain the old type 2 virus and it managed to spread to people who weren't adequately immunized against it.
Vaccine-derived type 2 polio can spread in the environment in the same way as the more common type 1 or type 3. It has the same paralyzing effects on infected people as other forms of the disease.
Pakistan, Afghanistan and Nigeria are the only countries in the world where polio remains endemic. The government of Pakistan launched an aggressive campaign this year, in partnership with international health organizations, to vaccinate children and carefully monitor the virus's spread.

Stupid logic...
By the way this is what Mulla/Maulana say to prevent anti polio drive..
a) Polio is His punishment on human, Don't interfare his work
b) Its USA conspiracy to neuter Muslims (God don't allow family plannig)
etc....
OBL case has nothing to do with it...

USA spread the disease it was eradicated before , it reemerged as USA needed to run fake clinc vaccination
I don't think USA is going to do this. If proof is found they can be in deep ****, they can't have their image be damaged in such a manner.

USA maintains , all deadly strains from epedemics known to men even the 1913 flu virus which it keeps in its underground facilities in case , Russia ever decides to activate its strain ..
Similarly Polio was eradicated from Pakistan , it reemerged , only because USA needed to run their own campaigns to hunt down Bin ladin , if it was not for these medical campaigns they may not have been able to identify the dna matches to spot Binladin relatives or gene match
CIA does some dirty dealing , to complete its mission what happens to others is collateral damage
