Two down, one to go: After decades-long campaign, type 3 polioviruses are set to be eradicated
After months of bad news, the international army of people who have been working for decades to eradicate polio will likely have something to celebrate this week. A global commission is expected to announce that type 3 polioviruses have been eradicated.
The announcement is expected on Thursday, which is World Polio Day. If it comes, type 3 polio will be the second species of polioviruses to have been vanquished. There were originally three types of polioviruses, named 1 through 3. With the eradication of type 3, only type 1 polioviruses remain.
