I spent 5.5 hours with my sister who is in my support bubble on Friday they developed symptoms on Saturday (they are doing the 2x a week lateral flow tests). There was no social distancing etc we were talking and hugged etc.
I know that I have to self isolate and I am doing so, I am just wondering how likely is it for me to actually have caught it? She only has mild symptoms, and her partner has none. But ive googled that people are most likely to spread it within the 48 hours before they test positive?
