A new computer model from Northwell Health is showing in great detail just how bad the flu season is on Long Island.

Northwell Health's Mark Swenson says that the company’s Biosurveillance Influenza dashboard features a map that allows Northwell Health to keep track of a case rate uptick and allows them to respond to their facilities and determine what resources are needed at those facilities.

The map can look at various amounts of data, including a three-day outbreak or even two-week period of flu cases to see how case rates have increased.

The data complied can be given to local agencies to let them know there is an uptick in the flu in that area and make sure that all the resources at those facilities are taken care of and make sure that those hospitals can help the community.

Swenson says it can also help the community by making sure they are aware of the cases and need to be vigilant in washing their hands, covering their mouths when they cough and coughing into the crook of their elbows.

The dashboard currently looks at 12 facilities as part of this program.

The Nassau Health Department released figures Tuesday showing a huge jump in flu cases. There were 2,082 cases reported in the county in January. There were 1,254 cases reported in Jan. 2017.
