Filtering DataFrame on String

Gahhhh… I show my ignorance. I have searched here and cannot quite get the answer.
In the Kaggle covid-19 dataset I read covid_19_data.csv into a DataFrame
The columns are:

julia> names(df)
8-element Array{Symbol,1}:
Symbol(“Last Update”)

How can I create a second data frame which has let’s say Country/Region UK

something like filter(x -> x[Symbol("Country/Region")] == "UK",df)
