COVID-19 exposure: This depends on the details of your contact with the infected person. If you're well across the room (at a well separated station) and ventilation is good, maybe no problem. If you were closer, shook hands, shared a break, you need to self isolate and get tested. Probably you're a federal employee (FAA), which must have its standards; check with your supervisor and follow them. Good luck.

COVID 19: How close was contact? Less than 6 feet apart? Both wearing mask? Person appear ill at the time? Outdoors or in poorly ventilated, crowded tight space? Less than 10 minutes? If someone who is infected coughs or sneezes right at you, you can become infected. The Aviation industry tends to have high standards - they likely have a policy about this. Check it out.
