| An Indonesian child receives a polio vaccination in Jakarta |
The latest cases were found in the provinces of Banten and West Java.
One case was recently reported on Sumatra Island, indicating the sometimes crippling disease has spread beyond the main island of Java.
Millions of children in Indonesia have already received emergency vaccinations against polio, which has reappeared in the country after a 10-year absence.
Indonesia is one of several countries where polio has re-emerged since 2003, and the first outside Africa and the Middle East. The outbreak has been traced to northern Nigeria, where hard-line Muslims boycotted a vaccination campaign.
