Polio, which a few years ago was on the verge of
being eliminated globally, is coming back, according to the WHO. Polio is a virus that mainly affects children
under 5 by multiplying in their intestines and then attacking the nervous
system. It spreads through infected
water. There are vaccines but no cure.
The WHO has issued a “World Health Emergency.” There were 68 deaths by
the end of April this year compared to 24 in the same period last year.
Polio is endemic in three countries: Pakistan, Afghanistan and Nigeria. It is spreading in and from Pakistan because
Islamic militants have blocked vaccination programs there. Syria, which was polio-free for 14 years, has
now been inflected from Pakistan.
