I know I keep banging the same drum but without numbers of households it’s still largely irrelevant. I saw a news programme today where a girl had symptoms and her mum was trying to get tests for their family of 8. She’s got 3 so far and still trying to get the other 5 but, if her daughter is positive, they will all need to isolate. If they are all isolating but all test positive at some point, it’ll be an 8-fold increase which just won’t be true. Areas that have houses of multiple occupancy will be at the forefront of large rises in cases, without necessarily making things worse.
