I have been wondering about this myself! Both myself and boyfriend were really ill in January 2020 - what we thought was a bad bout of flu, but we felt considerably worse than we had with flu in a while, and we both remember having a tight chest. That was back when Covid was just another sideline news item and just something that was happening in China. I remember reading that ONE person had tested positive in the UK, but we weren't worried because we thought it would be contained. Crazy how a few weeks later we were in lockdown.
Anyway, sorry that's not the point! You just made me think about how crazy its all been...
I've never once tested positive and after the first six months of panic and fear, me and boyfriend and my parents started mixing with a select few people, then increased it gradually to the point of hugging and freely socialising, even during times they were telling us to still be careful. Boyfriend's family have all tested positive, but never him, never me, never my DM (DF has never bothered with testing).
We have all occasionally had cold like symptoms (nothing major) and done the test, but always negative...I have wondered how this can be, when I know lots of people who have tested positive at least once, and once the first six months were over I was fairly liberal in my approach to socialising.
I am double vaccinated but was late to get them because of phobia of needles, and haven't yet been able to psych myself up for a booster (my second covid jab was awful, I nearly passed out) so I'm not even fully protected. Very strange!
