Remember that a major defense mechanism for the body is to induce fever to elevate the core temperature. Many viral and even bacterial infections do not do well with the elevated temperature (even a small increase of 1-2 degrees). The fever could have helped trigger the seizure, but I would be much more curious about what induced the fever that proceeded the seizure.
You should give the Bio Care Hospital & Health Center a call (800) 701-7345. It's a hospital in Mexico. I highly suggest you give them a call.
