The World Health Organization has declared Indonesia’s polio outbreak officially over, following nearly three years of intensive response efforts, officials said Friday.
Indonesia has remained largely polio-free as the highly contagious disease was declared eliminated in the country in 2014. But eight years later, an outbreak emerged in the country's conservative Aceh province, prompted by a dangerous combination of consistently low routine immunization and unhealthy environmental conditions. In 2021, only 50.9% of infants born in Aceh received polio vaccination.
