Not necessarily. If you usually one get one or two per hundred thousand and that goes up to 5 or 6 or 8 or 10 then it is possibly telling you something. They are keeping an eye on this increase. It may be nothing or it could be something.It's sensationalism.
0-100 sounds like a big increase but that's 100 possible cases, not all confirmed.
That's one hundred possible cases out of a population of 750,000,000 People.
