NORTH CAROLINA — The number of cases of novel coronavirus, also know as COVID-19, in North Carolina jumped by more than 100 overnight, according to the North Carolina Department of Health and Human Services.

The news comes hours after Mecklenburg County health officials confirm that as many as a third of the county's 106 cases come from community spread. Community spread means the person came in contact with COVID-19 through unknown means and not through travel or by direct contact with someone who has tested positive.

"Every zip code in our county now has a positive case," Mecklenburg County Manager Dena Diorio said in the town hall Monday. "And what that tells us is we do have community spread." Since health officials are unable to determine the source of the spread, residents must treat every interaction as a potential source of COVID-19 exposure, she said, the Charlotte Observer reported.
