According to the CDC, the threat of cyclospora has receded quite a bit. The outbreak seemed to been confined to summer months, and not as many new cases have been reported. Still, there is a need to keep an eye out and be proactive. This is why the CDC always needs to be robustly funded.
No, we as a society should not be worried about the cyclospora outbreak as with every other outbreak in the modern world, it will certainly be contained. Every major outbreak in the modern world has been contained, from bird flu to the so-called super flu, so I see no reason this one will be any different.
