Health officials in Bangladesh are launching a campaign to vaccinate at least 18 million children against polio after a nine-year-old girl was diagnosed with the disease earlier this year.
The health ministry says the campaign will start Sunday and will focus on children under the age of five. The government had thought it had eradicated polio, with no new cases reported since 2000.
But last month, polio was confirmed in a girl from the eastern district of Chandpur. The girl was first stricken in January. The World Health Organization reports that a lab in India linked the virus carried by the girl to a strain found in India where polio is still common.
