So what’s the cause? Is it “super bugs” resulting from overuse of antibiotics? Has increased hygiene somehow suppressed the development of these students immune systems?
This would be my guess but can instances these days really be considered frequent? It still seems pretty rare. Nevertheless it's scary as hell because the symptoms are something I wouldn't go to the doctor for. My nurse friend says an extremely bad headache coupled with a fever is a common first sign. Then you might consider going in for the definitive diagnosis via spinal tap. Yay.
I think people who constantly wash their hands and use sanitizer are definitely lowering their immune systems. I avoid antibiotics too. I figure I get enough from the groundwater.
