We strongly suspect some of my close relatives had it, all in the UK. My aunt became quite sick with coronavirus symptoms during her self-isolation following a long haul international flight back to London. My brother-in-law was similarly ill after attending one of the last Bundesliga games before its closure and flying back to London. My sister then got very mild cold-like symptoms. She works in a London hospital and a large percentage of her colleagues definitely got it, but she's never been tested. All of this was at a time when you couldn't get tested in the UK unless you were being admitted to hospital. Don't know anyone in Australia who has got it, though one of my colleagues living in a hot spot in the eastern suburbs of Sydney knew about 3 people who tested positive. It's interesting the extent to which people now associate the US and UK with danger. Like, if someone has just moved back to Australia from one of those countries, it's like "wow, just escaped in time". And if you know someone still living there, you always say a very sincere "stay safe" at the end of a conversation.
