FIGURE 2.

The figure is a diagram showing numbers and dates for acute flaccid paralysis cases and environmental samples positive for circulating vaccine-derived poliovirus type 2, which were associated with cVDPV2 outbreaks ongoing during July 2019–February 2020, that involved international spread since emergence, by outbreak and country, in Africa during October 2017–February 2020.

Acute flaccid paralysis (AFP) cases and environmental samples positive for circulating vaccine-derived poliovirus type 2 associated with outbreaks ongoing during July 2019–February 2020 that involved international spread since emergence, by outbreak and country — Africa, October 2017–February 2020*,†

Abbreviation: CAR = Central African Republic; DRC = Democratic Republic of the Congo; ENV = environmental surveillance.

* Dates (month/year) refer to the date of specimen collection. For samples collected on the same dates, symbols will overlap; thus, not all isolates are visible.

Data as of March 25, 2020, for all emergences except the following: 1) SOM-BAN-1 (as of March 24, 2020) and 2) CHA-NDJ-1, NIE-JIS-1, and TOG-SAV-1 (as of March 27, 2020).
