For me the concerning thing is not the strep itself - if you know what you're looking for and get the antibiotics in good time, there's no real issue.

The concerning thing is the reported shortage of antibiotics and people - for want of a better term - "panic buying" (or "panic prescribing") them. There is apparently a looming antibiotics shortage... and that is when it starts to be worrying. These infections can be fought effectively with antibiotics, but you do NEED the antibiotics, there's a reason that "Scarlet Fever" was a very scary thing to hear before penicillin.
