My friend asked me to pick her up her two kids from school on Friday and have them over for a few hours as she has somewhere to go. Both her kids are in the same classes as two of my children and they often play together. On Tuesday the older sibling of my friends kids had a high fever and cough, he tested positive on Wednesday. The siblings are still attending school in line with the government guidance. Would you still have the siblings in your house? They are currently symptomless and she said she will give them a LF test on Friday.
