As Google morphs from a search engine to a content destination, it rolls out a new update for the medically minded.
According to the Google blog: health info in the Knowledge Graph
"one in 20 Google searches are for health-related information
So starting in the next few days, when you ask Google about common health conditions, you’ll start getting relevant medical facts right up front from the Knowledge Graph. We’ll show you typical symptoms and treatments, as well as details on how common the condition is—whether it’s critical, if it’s contagious, what ages it affects, and more..."
So no more Doctors visits, you can now Google diagnose yourself and the NHS should save a fortune 
On a more serious note, this is probably the most obvious visual signal of where Google is going and how it is utilising it's growing Knowledge Graph.
It won't be long now before Google will want to drop the term "search engine" as that will be seen as a relic of the early internet.
