Ann: Zoono Supplies Commonwealth Games Athletes, page-19

I hear you point that it may not be the best look, but there's no reference the Zoono products failing.

I see it that this athlete had contracted the mumps disease before arriving & only now the symptoms are showing (16-18day period), you could say zoono product working as no other athlete in NZ team has contracted mumps. Yes in isolation now, but I'm sure there was a window before being placed in isolation that it could have spread, but didn't due to zoono product effectiveness.

Zoono products aren't cures, they protect from further spreading of germs.
