I was just kidding around and wasn't comparing the journals.
However, you have to pay to publish in almost every academic journal. In the old days when it was just paper journals you'd pay ~$100 per page plus extra for color figures, now most journals have a flat publication fee and then require extra for open-access. That's the way it is in my field but perhaps the medical field is different. A predatory journal is one that the seeks submissions, charges you a submission fee, and publishes anything and everything submitted for a fee without any vetting or review. I know a guy who crowd sourced the publication fees to get a paper titled: "What's the deal with birds?" published in the "Scientific Journal of Research and Reviews" (The journal deleted the paper from their website following several media articles about predatory publications). It doesn't look to me like the International Journal of infection Disease falls into that category.
