Hi At Mum's CH they used to bake a cake for each resident when it was their birthday complete with at least one candle. Pre Covid they would all sing Happy Birthday. Luckily I have a video of Mum blowing out the candles on her cake with help from a friend on the same table.It's appalling, isn't it? The main source of infection in care homes is due to people coming and going, whether that is carers, medics or visitors. But visitors are seemingly hosed down with bleach for half an hour and have to stay behind a brick wall so they are unlikely to be bringing in much. (And very often visitors are extremely careful with social distancing themselves, meticulous about hand washing, etc, or even shielding, so again, unlikely to be much of a threat.)
I would like to see evidence of one person - just one - who has caught covid from an under-quarantined cake.
