Refined Results for Health Terms

Anyone else see this?

[One Thing Well]

Search "strep throat" at Google and see the following category breakdowns:

Treatment Tests/diagnosis For patients From medical authorities
Symptoms Causes/risk factors For health professionals Alternative medicine

I don't see this in any other category yet.

Also can't find any reference to it in Google Help or FAQ

The question behind the question is... Will my ads show up under these categories? Is it human-reviewed?

I saw that for at least a couple of weeks, especially with pure city name searches.

It's been on health terms for about a month now. Seems to have something to do with Google Coop. Apparently Google created a coop (or however it works) related to health.

Yes, ads still appear when the users click on the refinements.
