Viruses don't discriminate, but immigrants (and descendants of immigrants) do tend to visit their original home countries (and/or ancestor's home countries) more than the rest of the population. People of Chinese descent living in Italy are more likely to visit China than people of Italian descent in Italy (or Irish or whatever non-Chinese descent). Areas with high concentrations of Chinese people are thus more likely to have been exposed to a traveler than some other areas. There's nothing racist about this. Of course hot spots for transmission like airports will spread it beyond the Chinese communities.
