Did he ever wear that ring before the 2018 WEF? I've been trying to find earlier photos of him, but it's not easy.

After that day he started carrying it on the other hand.

Where do you see that? I just searched the entire paper for the word "human" and did not find any mention of human subjects or trials.

According to the CDC Covidnet map legend:

*This map uses the proportion of outpatient visits to healthcare providers for influenza-like illness to measure the ILI activity level within a state. It does not, however, measure the extent of geographic spread of flu within a state. Therefore, outbreaks occurring in a single city could cause the state to display high activity levels.

Are they tracking flu or the china virus?

Surprisingly enough MSM seem to have published the complete list:
