Temporarily, no visitors aged 11 and under are permitted. This year's dominant flu virus is a mutated flu A virus that appears to make children and teens sicker than the typical flu. We are restricting visitors aged 11 and under because young children often can carry and transmit viral infections with no symptoms, especially early in the infection. As always, visitors should not come to the hospital if they have respiratory viral symptoms or nausea, vomiting, or diarrhea.
