Don't know if you've noticed, but Google has had a "feature" for some searches about certain health conditions where what you get as a search result is a doctor-curated quick refernce card about the condition. It's pretty cool. Try it out.

Well, there's some new, good news about it. Apparently it's working, and .. It hasn't been killed off by Google (as they often do with test features), in fact it has been expanded!

Google calls the results format a "panel" but it looks to me like what we old school geeks call a "quick reference card. You can even download them in PDF form and turn them into a card, if you wanted to.

Google's health conditions feature is about making it easier to find information about an illness. So, when there's a local outbreak, or you get early symptoms, you can be better prepared. Mountain View has doubled the number of diseases in its database, bringing the number up to over 900 -- including neglected tropical diseases and infections that typically affect people in developing nations. If you do a query for any of those illnesses on either mobile or desktop, you'll see a quick results panel, which contains info on its symptoms, treatments and prevalence.

You can even download the panel as a PDF file that you can print -- apparently, that's the most requested feature among the doctors Google worked with to ensure each condition's accuracy. Unfortunately, the feature remains accessible only via Google US (that's, or the one without a country-specific domain), but the company promises to make it available in more languages in the future.
