As we near the end of 2013, NPR is taking a look at the numbers that tell the story of this past year; numbers that if you really understand them, can give insight into the world we're living in right now. Over the next two weeks, you'll hear the stories behind numbers ranging from zero to a trillion. This morning, our number of the year is 223. That is the lowest number of cases of polio ever recorded in the world. And 2013 was on track for an even lower number on the road to complete eradication of the virus.

But this was a year when polio pushed back. The virus reappeared in Somalia and Syria. It showed up in sewer systems in Israel. It spilled out of Nigeria into Cameroon. Pakistan saw a spike in cases, as well.

Even so, NPR's Jason Beaubien reports global health officials are still confident polio can be defeated, and soon.

JASON BEAUBIEN, BYLINE: Global health officials could be forgiven for thinking that 2013 was going to be the year, the year when they'd finally stop polio in its tracks. Earlier campaigns had predicted that the virus could be banished by the year 2000, but that obviously didn't happen.

SONA BARI: I think I'll start with the bad news.

BEAUBIEN: Sona Bari, with the World Health Organization in Geneva, says yes, there were disappointments in 2013.

BARI: If you look just at the number of cases, of course, we have a large rise in cases over 2012 to 2013. More than 70 percent rise in cases. We have eight countries reporting polio as opposed to four last year at this time.

BEAUBIEN: Polio had hit a historical low in 2012, with only 223 cases reported worldwide. New outbreaks this year in the Horn of Africa and Syria surpassed that all by themselves. So how much of a setback is this to the decades-long, multi-billion dollar polio eradication effort?

BARI: I think it's a huge setback when your child has been paralyzed for life. When you live in a country like Somalia or Syria, where possibly you're in a conflict-affected situation. This is the last thing you need. This is the last thing any parent needs. From a global polio eradication perspective, these are things that are unfortunate spillovers until endemic polio is stopped in the three remaining countries.

BEAUBIEN: The three remaining endemic countries: Afghanistan, Pakistan and Nigeria; the three countries on Earth where polio transmission has never been stopped. There was some progress in these places this year. The number of cases in both Afghanistan and Nigeria fell significantly. Pakistan, on the other hand, saw things go in the opposite direction. In addition, militants have made it impossible for vaccinators to immunize children in some tribal areas in the north of the country.

But despite the overall rise in polio cases this year, Bari says there's been progress on several fronts.

BARI: For the first time in history, we have only one type of polio. All these cases are Polio Type One, and this has never happened before. We haven't seen Type Three for over a year now.

BEAUBIEN: Not to get too technical, but there are three strains of the polio virus - each requiring a different vaccine. Type Two was last seen in 1999. This year, Type Three dropped off the map, leaving just Type One Polio for public health officials to contend with.

Michael Klag, the dean of the Bloomberg School of Public Health at Johns Hopkins in Baltimore, says polio eradication is finally within reach.

MICHAEL KLAG: If you look at where we are, it's incredible what we've accomplished and we're almost there. We cannot stop now.

BEAUBIEN: If polio is wiped out, it would be only the second human disease ever eradicated.

KLAG: We know that at the very end of any campaign like this, the last few countries, the last few cases are always much, much harder than the preceding 80, 90 percent.

BEAUBIEN: So far, billions of dollars have been spent in the drive to eradicate polio. The expectation is that it will take billions more to stomp out the last few cases and ensure that polio doesn't stage a comeback. The challenge now is to sustain the political will for such a massive global campaign all the way to the end.

Last year, William Muraskin, a professor of urban studies at City University of New York, came out with a book called, "Polio Eradication and its Discontents." He calls the whole polio eradication movement a failure, driven by the egos of Western health officials, that's consuming resources that could be better used elsewhere. Muraskin argues that the world would be better off trying to contain polio at low levels, and focus on other simpler health challenges.

WILLIAM MURASKIN: Putting money into routine immunization systems, that's not attractive. That's boring. And no one is going to get a statue for strengthening routine immunization systems.

BEAUBIEN: So far, Muraskin is an outlier in a sea of voices pushing to stamp out polio once and for all. Polio eradication campaigns however, do sap scarce resources in places like Nigeria and Pakistan. And if the polio eradication effort drags on indefinitely, more critics of the strategy are likely to come forward.
