I have a broad distrust of any information produced by the Chinese government. So I am suspicious of their claim that the outbreak is contained, yes - but I'm equally suspicious of their claims about infection rates, their claims about what actions the government is taking, and the implicit assumption that the actions they claim to be taking are necessary or warranted.

What I distrust a lot more is uncorroborated reports of divergent numbers, because there are just so many ways they could be wrong. For example, I saw one source claiming ironclad proof infection rates are 3x higher than reported - because a document they posted showed the number of positive coronavirus tests run in a day, and it was higher than the number of new cases reported that day. (And I'm extending the very generous assumption that the document was real, but how would anyone know if it wasn't?)
