Ok, no, you can't really say that. CPS doesn't act as a court of law. Essentially they bring forward a case if there's sufficient evidence for a realistic prospect of conviction, and if a case is in the public interest. Realistically public opinion also factors into the latter.
So, negligence and recklessness are both pretty complex concepts. The quantitative (remit / extent) and qualitative (eg foresight, virtual certainty) elements of their definitions have morphed a lot over years of case law, and still remain the subject of debate before.
The facts of this case have also not been held up to scrutiny (in a legal sense, not by the police), eg did she ever experience really mild symptoms but write them off?
That's of course assuming the need for some kind of moral responsibility, in an entirely subjective layman sense. In any case, there here have been precedents where people with less moral responsibility (again in a non-legal layman sense) than this woman have been found guilty, for many reasons eg causation, policy, binding precedent, weight of future precedent on dissimilar but adjacent cases.
Also, there are conceivably two ways this could go if she were to be let off – one would be lacking the necessary elements in the first place, and the other would be being found guilty. It's not as simple as it looks. So really all the people on this thread acting as judges are making me feel quite taken aback...
