The World Health Organization (WHO) Africa recently confirmed that the African country of Angola had been free of wild poliovirus since July 2011 and declared the interruption of polio transmission in November 2015.
Unfortunately, Angola recently reported a concerning development in early 2024.
Four cases of Poliovirus Type 2 have been detected in environmental samples of sewage water collected in two provinces. Additionally, two cases of Acute Flaccid Paralysis (AFP) have been reported in early May 2024.
