Track and Trace Apps— How do they work?

~ this could end up becoming a real pain if I get notified when I was not at real risk of catching the virus from them.

Is bluetooth and the app capable of measuring the two key factors in aerosol transmission of the virus?

So when will I be notified i’ve been in contact with a Covid carrier?

When a user of the NHS Track & Trace app confirms that they have Covid the phone uploads the last 14 days exposure log to the server and it then shares the information to other people you have come in contact with, your phone receives these updates of infected users through the app based on this information it works out your exposure risk value for the matches.
