I tested positive for Covid yesterday, currently with 'heavy cold' symptoms. We've changed our plans for Christmas Day as we were planning to go to my parents and my mum is in remission from cancer. My inlaws live overseas but are currently staying with sister in law (5 hours drive away). The original plan was that they would come to ours on Boxing Day and then stay for 10 days before returning home. DH called them today to say I had covid and suggest they stay where they are for a few extra days or go and stay with other relatives. Their response was 'it doesn't matter, we've both been vaccinated, we're not going to change our plans'. Both inlaws are in their 80s with a variety of health issues. If either of them caught covid they risk serious complications. I think we should just tell them directly they can't come until I test negative, DH says the decision to visit is up to them (although if I became too ill to have guests he would obviously tell them that). AIBU?
