A spokesperson for the U.S. Embassy in Beijing said that on Thursday, the State Department had ordered the departure of family members and all U.S. government employees at its Wuhan consulate, but declined to comment on the report that other U.S. citizens would be evacuated from the city.

It's to move consular staff.

The decision to move U.S. consulate staff and families was due to the outbreak of the coronavirus “and logistical disruptions stemming from restricted transportation and overwhelmed hospitals in the city of Wuhan,” the spokesperson said in a statement emailed to Reuters.

Doesn't even mention US citizens. The State Department hates them. They wouldn't piss on you if you were on fire. Contrast this to other countries whose consulates are going full on to help their people.
