Strange phone call that my Wife had yesterday......

So my Wife shattering her ankle & had to have surgery(a plate with 7 screws & 2 "pins", which look an awful lot like 2-3 inch screws to me). About a week after her surgery 3/4 of the incision, over the plate, opened up, down to the muscle. The Dr arranged for Wound Care Specialists to come to our House. During the scheduling call, the Woman asked my Wife, "Does anyone in the house have Ebola?". My Wife said, "Pardon me?". The woman repeated her question & my Wife answered, "No Ma'am.". "Has anyone in the house had any contact with anyone who has Ebola?". Again, "No Ma'am.". "Has anyone in the house traveled outside of the US our outside of Texas in the last 21 days?". Again, "No Ma'am.". "Has anyone in the house traveled more than 200 miles from home in the last 21 days?". Again, my Wife answered, "No Ma'am." But my Wife went on to ask, "Are these new questions or is this something you always ask?" & the Woman replied, "These are just things we need to know.", clearly giving a non answer. We live in Central Texas, what is known as The Hill Country and The Highland Lakes area, about an hour & a half West/Northwest of Austin.
Thought it was strange enough to share.
