Starting Monday, children under age 5 will be barred from visiting patients at most Twin Cities area hospitals.
The new limits were announced at a joint news conference Friday, as hospitals increased efforts to keep patients and visitors from infecting one another with the H1N1 flu.
The new restrictions, which could last for the duration of the flu pandemic, will take effect at Hennepin County Medical Center, North Memorial Medical Center and all Allina, Healtheast and Fairview hospitals.
In most cases, the new rules go further than the restrictions announced only a few weeks ago, when many hospitals started limiting visitors to maternity centers and children's units.
Now, the limits will apply hospital-wide.
Those hospitals no longer will allow visitors younger than 16 unless they're immediate family. Some are tightening visiting hours, as well as the number of people who can visit at once.
"We understand that these policies may inconvenience some people," said Dr. Steve Bergeson of Allina Hospitals & Clinics.
But "we truly believe these actions are needed and in the best interest of patients and staff."
