So Taiwan, who is blocked from being part of the WHO, warned them about the virus and human-to-human transmission in December, and were ignored.
Meanwhile, WHO spread misinformation provided to them by China, as late as mid-January. According to them at this time, there was no evidence of human transmission, and none of their healthcare workers got infected. The virus went away as soon as they shut down the Wuhan wet market on Jan 6.
Edit: I should remind people now, don't blame "China" for this, blame the CCP. The citizens of China were not involved in the lies, and in fact they tried to "whistle blow" and were arrested and silenced for their efforts.
