I woke up with a headache and a sniffly nose this morning. I read in the Guardian of a woman with the same symptoms who was amazed when she tested herself positive. I've just done another test, so two days in a row, and I'm negative. I don't have to recall Mrs Steve from her visit to her 75-year-old friend. So that would have cost me $50 in the US? That doesn't strike me as the way forward...
