Self-isolate for 10 days
The app has detected that you have been in contact with someone who has coronavirus. Please stay at home and self-isolate to keep yourself and others safe.
You are at high risk at having and spreading the virus even if you don't have any symptoms. If you are under 18, you are advised to show this message to a trusted adult.
Well, shit — an acquaintance of mine who i'd been in close contact with last Friday tested positive for the plague, and the NHS covid-19 app (which you really must get if you're living in the UK and your phone supports it) flashed up a notification informing me that i was grounded for the next ten days.
It's strange; i've no idea how it could have happened, given that educational institutions are impervious to coronavirus infection. (Why else would they remain open during lockdown 2.0?)
I'll keep you updated if i develop any symptoms…
