The state Department of Health today confirmed a total of 56 cases of the dengue fever outbreak on Hawaii island. 

That number is up from 49 this weekend. 

Officials said the cases include 46 adults and 10 children, with the onset of the illness ranging from Sept. 11 to Nov. 7. 

Dengue is a viral infection spread via mosquitoes that bite an infected person and then carry the virus to the next person. People cannot infect other people. 

While dengue is not endemic to Hawaii, it is intermittently imported from endemic areas by infected travelers. 

The recent cases mark the first cluster of locally acquired dengue fever since the 2011 outbreak on Oahu, when four cases were confirmed.
