Don't lose sight of the fact that those 5 positive tests are just among those who've actually been tested for COVID-19. How many people do you know that have been tested? Personally, I've yet to hear of anyone in my various circles who's gotten a test.
Then factor in that the virus allegedly doesn't show symptoms early on, i.e. you can be contagious and not know it. This compounds the problem.
You have people who may be infected, have no idea they're infected, yet still going about their business interacting with people, not washing their hands frequently, etc. etc. unknowingly spreading their COVID cooties all over the place. Fast forward two weeks, they suddenly find themselves down with the sickness with God knows how many people they've interacted with not far behind them.
So if 5 people tested positive, ask yourself how many people have they crossed paths with in the last two weeks before that initial person had any clue they were infected?
Point being, it's here. That's a proven fact. It's being spread around as we speak. Positive test numbers should be viewed as the canary in the coal mine, they're an indicator, nothing more. The best defense at this point is to limit your exposure/interactions. Sucks, but that's reality at the moment.
