Well, they could take a leaf from India and just rename the city? Although, politically motivated in India, it works. Eventually Bombay became Mumbai, Bangalore is Bengaluru, Madras is now Chennai and what was known as Allahabad is now Prayagraj.
That’s a very different context than a virus originating from a particular area.
Also, in India the colonial reference was the official excuse. In my view, it was purely a show of political power.
Failing that, local culture would refer to those cities by those reticent names somewhere. Local newspapers, pamphlets, propaganda material. No evidence of that.
