As the number of people in New Jersey who tested positive for the coronavirus continued to climb Monday, Lt. Gov. Sheila Oliver and others urged residents to remain “calm,” yet be prepared.

State officials urged people to have two weeks worth of food, medicine and water at the ready in their homes in the event of a self-quarantine. The guidance came at the same time five additional people tested positive in the state, pushing the number of cases in the state to 11.

“If someone is placed in quarantine for 14 days, we’re urging people in quarantine not to go out in the community,” state Department of Health Commissioner Judy Persichilli said at a news conference in Ewing to procide an update on the coronavirus.

The medicine should include personal prescriptions, as well as things like fever-reducing over-the-counter drugs, she said.

At the same time, officials are urging people in the state not to panic because the risks for most New Jerseyans of catching the virus means low.

“If all remain calm and informed, and educated with each passing day, and just practice common sense, the risk of an individual contracting coronavirus remains low,” Oliver said.

That means staying home if you’re sick and practicing good hygiene, she said.

The announcement came as Oliver said the number of confirmed coronavirus cases in New Jersey rose to 11 on Monday, with five more infections announced by state officials since Sunday. They also said 27 additional people in the Garden State are under investigation as potential cases by the state Department of Health.

New Jersey’s state epidemiologist, Tina Tan, said they continue to “monitor what’s going on” and try to find links between the new cases to stem the rising numbers. Tan said they can’t point to any cases in the state where somebody caught the virus who reportedly did not have relevant travel history or exposure to another known patient with COVID-19.

“At this time, there does not appear to be sustained community transition," she said, referring to so-called community spread of the coronavirus.

The five new cases announced Monday by state health officials include:

An 18-year-old from Clifton was exposed to coronavirus after having close contact on March 2 with a person in New York who was a known positive case. The Passaic County resident, who is not hospitalized showed an onset of symptoms Friday.

A 48-year-old Berkeley Heights resident was exposed to coronavirus after having contact with friends who traveled from Milan, Italy. The Union County resident showed an onset of symptoms March 1 and is hospitalized at Overlook Medical Center in Summit. The friends tested negative and the case remains under investigation. Officials called it an unusual case.

A 27-year-old Little Silver man who attended the attended the Biogen conference in Boston from Feb. 24-28 showed an onset of symptoms on Feb. 29. Though he is not hospitalized, 170 conference attendees have tested positive for coronavirus.

Meanwhile, the coronavirus outbreak continues to spread across parts of the United States, with more than 560 confirmed cases reported and 22 deaths as of Monday morning, according to public health agency data compiled by Johns Hopkins University.
