Description:Captured in 2011 in the country of Chad, officially the Republic of Chad, by U.S. Centers for Disease Control and Prevention (CDC) Medical epidemiologist, Katrina Kretsinger, M.D., this photograph was created during the country’s polio vaccination campaign. With his head tilted back to receive the dosage, this young child was in the process of receiving an oral polio vaccine being administered by a healthcare field worker. Though Chad has successfully stopped the transmission of polio, the country has not yet been certified free of this devastating disease.
“Indigenous wild poliovirus transmission (WPV) has never been interrupted in Afghanistan, Nigeria, or Pakistan. Polio transmission was reestablished (defined as circulation for =12 months after importation) in four, previously polio-free countries in Africa, including Chad, in the 2000s.”

“WPV circulation during 2012 has continued only in Chad and the three remaining endemic countries. With ongoing WPV circulation in Nigeria and low routine immunization coverage, Chad remains at risk for new WPV importations and outbreaks. The polio program in Chad has made progress in 2012, and continued efforts will be required.” (See link below)
