NORTH CAROLINA – Flu season is still a month or so away from its peak, and health officials are urging people to get their flu shots with the number of cases continuing to rise.

Because of the uptick in cases, all Duke University Health System hospitals began restricting visitation rules on Monday, including ambulatory surgery patients being limited to immediate family or designated care givers, 18 and older, those who are not sick with the flu, and patients can’t have more than two adult visitors at once.

The restrictions are only temporary; Duke put similar restrictions in place last year.

Health officials are still stressing to the public to get flu shots. It takes about two weeks for the vaccine to kick in once administered. Some pharmacies have noticed an increase in demand and therefore a decrease in supply.

Eight people have died from the flu in North Carolina this season.
