You can search at the top for symptoms: https://imgur.com/a/y5RUk5x

I'd say if I were to suggest improvements the symptom search could definitely be better and more prominently placed. In the UK I personally (and I'd imagine most people) get to the NHS website directly from Google, which is better at finding more relevant pages.

That doesn’t really help. It just vomits a list of articles that mention coughs. The “killer” (rescuer?) feature of WebMD is being able to start from a symptom and narrow down through clarifying questions. You implied the NHS does this better, when it doesn’t attempt that feature at all.

I’m not sure this is the prime “UX done well for symptoms->cause” example you cited it as. Though I agree UK government sites follow much better UX patterns!
