Which wild poliovirus type has been declared eradicated, reducing the risk from that serotype?

Explanation:
There are three wild poliovirus serotypes, and eradicating a serotype means there’s no evidence that that serotype is circulating anywhere in the world. Wild poliovirus Type 2 has been declared eradicated, so the risk from that serotype has been eliminated. This status reduces overall polio risk and has influenced vaccination strategies, including moves to minimize outbreaks related to that serotype. The other serotypes—Type 1 and Type 3—have not been eradicated and can still cause outbreaks in some regions, so the remaining threat comes from them.
