More than 3.3 million children have been vaccinated against polio in Chad in a just-concluded immunization drive one of the largest of its kind in the African region.
As this year’s campaign is halted due to the COVID-19 pandemic.
While Africa was declared free of the wild poliovirus in August 2020, another form of polio continues to infect children.
This type of polio is rare and can only occur in areas where not enough children are immunized, which means that the only way to stop their spread is through immunizations.
The current outbreak in Chad was first detected in February 2020, but immunizations were halted due to COVID-19, and the virus spread to 36 districts across the country, paralyzing more than 80 children and even leading to cases in neighbouring Sudan and the Central African Republic.
