Taiwan warned the WHO about human to human transmission on December 31st: https://www.taiwannews.com.tw/en/news/3904054
I searched for the sources, and all that I found is that Taiwan asked WHO more investigation and verification of China's affirmation. Taiwan did not add any study results or scientific knowledge, so had nothing to really "warn" about. The China "results" were actually biased, so Taiwan was right to ask verification, but that's only retrospectively. At the time, there was no such certainty of their wrongdoing, especia…
The reason you didn't find much is that the WHO refused to pass on Taiwan's warning.
Taiwanese doctors had direct emails from multiple colleagues in Wuhan, some of whom were punished by the local government for speaking. Doctors getting sick with the virus was direct evidence of human to human transmission.
Keep in mind that China also covered up and denied the existence of SARS for months. The WHO's decision to aid in suppressing the information of the epidemic has cost the entire globe countless lives and economic damage. What is it that so motivates you to defend them that you comment 20 times in this thread?
FWIW, I've followed the news this time and during SARS from the start, from local media in Taiwan and been deeply disappointed with the WHO and early international reporting both times.
