At last: contact tracing in Wales

I would like to say "I told you so", but unfortunately my Facebook comment on the first reported case of Covid-19 in Wales has long since been publicly unavailable. In it, I pointed out that South Wales in particular was vulnerable to an influx of Covid-19 carriers because of our familial connections with Bardi and surroundings. (North Italy was a known hot-spot of infection in Europe.) I did query what had been done about tracking contacts. Anyway, at long last we are to have contact tracing here.
