I'm a teacher and went to WDW in late January, so I am fairly certain I have been exposed. I've been in insolation since March 13 due to having to work from home. The headaches are not unusual for me due to allergies, but my husband, who's a school bus driver, doesn't usually have allergies. We're in our 30s, so testing us is not a priority and shouldn't be if that is all the symptoms we're exhibiting right now. My sons are not exhibiting symptoms (one works at the grocery store). We've been taking precautions with them.Q
Maybe you have a hotline in your area you can call, otherwise your family doctor if you have one.
I had sinus headaches for the past week but I frequently get them in the spring when tree pollen starts so I'm not worried. If that kind of headache is unusual for you, if you can't get a test done and you're not already self isolating I think it might be prudent to do so.
