The World Health Organization says Bangladesh's first case of polio in six years has been found in the Chandpur District of the Chittagong Division, southeast of the capital, Dhaka.
The Bangladeshi government says it will begin an immunization program in the area where the single case was detected. The W.H.O. says nearby Thailand and neighboring Burma have had no cases of polio in the past four years. And Bangladesh's giant neighbor, India, cut the number of cases in half from 2004 to 66 known cases in 2005. The W.H.O. has been undertaking a campaign to eradicate the polio virus in Southeast Asia. It says it provides member nations with immunization help and surveillance reports.
