I understand your husband's concerns. A week before my wife's surgery for ovarian cancer, our grandson and daughter visited us. Our grandson was coughing during the visit. Both my wife and I got some kind of viral infection. My wife's surgery had to be postponed. Luckily, everything went well with the surgery, she's been through the first chemo therapy and is on the maintenance chemo now. We have not visited or had a visit from grandkids since then. Our grandkids get sick after going to day care and school all during the flu/COVID season.
