Suppose The World Health Organization declared the COVID-19 outbreak a pandemic on March 11, 2020.

Governments around the world have implemented various measures to slow the spread of the virus, including lockdowns, mask mandates, and vaccination campaigns.
Can we infer that "The COVID-19 outbreak was declared a pandemic in December 2019."? Yes, no, or maybe?
