There have been only 16 reported cases of polio so far this year, according to the Global Polio Eradication Initiative. That is compared to 40 at this time last year. All reported cases this year have been from endemic countries, meaning that the disease is not being imported anywhere, a great sign. There are only three endemic countries left, Afghanistan, Pakistan, and northern Nigeria. All endemic areas are deeply Islamic.
Of the three serotypes, only one is still extant, having just eliminated the third serotype in Pakistani sewers. Type 2 went extinct in 1999 in India. This makes targeted vaccinations easier. Still, the campaign must be as tenacious as ever. Letting off the pedal now would undo years of work, as happened in the early 2000s. While there have been targeted killings of vaccine workers by Islamic extremists, progress is still being made. Kudos to those brave vaccine workers!!
Once there are no more cases, the world must wait three years to be certified free. Polio would be the second infectious disease of humans to be eradicated.
