An outbreak of polio in Tajikistan has undermined efforts to eradicate the disease worldwide and threatens to spread even further. This year alone, 452 cases of polio have been confirmed, with several more detected in neighboring Russia. Authorities have spent $7 billion since 1988 in a campaign to eliminate polio, which authorities believed would see its final stand in Asia or Africa. The World Health Organization says that the outbreak in Russia and Tajikistan -- both considered polio-free since 2002 -- threatens international efforts to eradicate the disease.
