Yes, spotting it is the first step
@Warm Braw, I agree. My partner is alive today only because an A&E admitting nurse thought something wasn't quite right with someone who was coming in with an inflamed knee and flu. It turned out the knee was a mass of sepsis and 24 days and expensive drugs later she came home with her life and both legs, but it was a near-run thing. But it looked like someone with flu and a bad knee.
