KIEV, Dec. 1 - The World Health Organization is urging Ukraine's health ministry to declare a state of emergency due to a polio outbreak, a move meant to prompt more action from the government in Kiev, AP reported.

In September, Ukraine announced two polio cases — the first in Europe since 2010.

The U.N. health agency recommended that Ukraine declare a state of emergency and "respond to the polio outbreak as quickly and effectively as possible," Dorit Nitzan, head of the WHO's office in Ukraine, told journalists.
