Hello, I work in a large children s hospital in L.A. Me and several of my colleagues have been experiencing extreme fatigue, malaise, headache, body aches, mental fatigue, and some have mild nasal/sore throat symptoms. We ve all had it for over a week and while improvement comes with lots of rest, symptoms are still continuing well into week 2. None of us have typical cold, flu or GI symptoms. I rarely ever get sick and I had to actually take 2 days off work and slept for 80% of each day. I m 55 and this is the first time I ve ever taken 2 days off. We cannot figure out what it is!
