I'm concerned for my parents , who are well into their 90s and for myself, as I have asthma, which is normally well controlled, but with infections can be serious. 3 years ago I had pneumonia after what was a minor, silly cough, which landed me in hospital and several months of recovery. Fortunately, I don't catch things easily, probably due to teaching young children for years. But I have no intention of isolating myself in case! Only if I have to. What will be, will be.
My son is in a difficult situation. He and his family are booked to fly here from the USA in a couple of weeks. If he cancels he won't get the cost of the air fares back. He has been told that if he does come over and has to go into isolation through contact, he could lose his job! He's a paramedic, so is probably at more risk at work! Some decisions and discussions with his HR department tomorrow.
