WOW!

I would be really angry. This recently happened to me, actually. Some incredibly bright parent at my DS's kindy kept bringing her child in and refusing to have him tested as she couldn't be bothered with the hassle. Turns out he had it. My DS developed a cough, so of to the dr we went. We were both tested and his swab was positive, mine negative. (which is surprising considering I've had a worse cough than he has). I was advised to treat myself as if I had it, having been heavily exposed. The hospital nurse who phoned me actually said she believes the test must have been wrong, judging by the way I was out of breath and coughing on the phone.

Anyway, we took our antibiotics, and I immediately informed my boss I wouldn't be in until our 5 days of treatment were complete. I also did not attend work or send my DS to kindy during the time it took for the lab to process our results either. It's just common courtesy and common sense not to spread a dangerous and infectious disease if you *THINK* you might have it.

You know what really gets me? The fact that I took all these precautionary measures, and still I had a nasty co-worker spraying chemical cleaner in the air anytime I was near him (which made it very difficult to breathe, and worried me, being pregnant...) and my boss interrogated me basically saying that I did the wrong thing in taking so much time off, and yet should have been more careful about spreading 'my disease'. wtf?

I would definitely speak to your boss about it. There are certain precautions which must be taken when dealing with these things. I would smack this woman upside the head for you, if I had the chance. Despite my test coming back negative, I've had 30 days of awful, retching coughing which causes me to vomit and wet my pants at random. It's horrible. And it doesn't seem to be letting up any time soon.
