Proceedings During the Pandemic (No. 4)

The problem with testing is that it tells us only whether someone has this virus; it does not tell us whether someone is in the process of developing it. Therefore, as I understand it—I am not pretending to be the Health Secretary—if someone tests negative in the morning, they may, none the less, have caught it the night before and be positive by the vote at 10 pm. Therefore, much as I wish that what my right hon. Friend was saying were the case, I do not think it is as straightforward as that.
