1. "by the Chinese authorities". So UN is not "saying" this, they are just relaying information and clearly marking it as such. 2. "Preliminary investigations..." so this was not presented as a definitive conclusion, just as preliminary findings...by someone else. 3. "... have found no clear evidence of human-to-human transmission..." This is not "there is no transmission" or even "found evidence that there is no transmission" and it's not even "have found no evidence for", but "have found no clear evidence for" So basically every word of your post is a mis-representation of the original tweet.
