New Jersey officials announced six new coronavirus cases Thursday, increasing the statewide total to 29 positive tests with 1 death as the outbreak continues to expand, prompting unprecedented closures, cancellations and rescheduling of events throughout the state.

Gov. Phil Murphy also issued a recommendation against any public gatherings of 250 people or more in the state. New Jersey declared a state of emergency Monday to deal with the unfolding outbreak.

“Today, based on guidance we have received from the Commissioner of Health, we are recommending the cancellation of all public gatherings throughout New Jersey of more than 250 individuals, including concerts, sporting events, and parades," Murphy said. “These measures are being taken as part of our coordinated response to the continued outbreak and to aggressively mitigate the spread of the virus.”

The six new cases include:

A 16-year-old girl from Englewood. This positive test was performed through Labcorp, rather than at the state lab. She is being treated at Englewood hospital.

A 66-year-old woman from Montclair. She is hospitalized at Hackensack Meridian Mountainside Medical Center.

A 51-year-old man from Bulter Borough. He is being treated at Chilton Medical Center in Pompton Plains.

A 23-year-old man from Bridgewater. He may have been exposed through close contact with a Pennsylvania resident who has coronavirus.

A 53-year-old man from Manalapan. He is being treated at CentraState Medical Center in Freehold and had exposure to a confirmed case.

A woman, age unknown, from Teaneck. She was exposed to a confirmed case at a synagogue carnival on March 1.

The new positive tests include the first cases for Somerset, Essex and Morris counties. New Jersey now has coronavirus cases in 11 of 21 counties. Bergen County has the most cases with 13 and is considered a “moderate risk” for exposure to coronavirus, state Health Commissioner Judith Persichilli said during a news conference in Ewing.

All other counties are considered a “none to minimal” risk with the exception of Monmouth County, which has five cases and is considered “above minimal," Persichilli said.

There’s another 37 possible cases under investigation. Those will be tested at the state’s lab, Persichilli said.

COVID-19 — the illness caused by the virus — has sickened more than 1,300 people nationwide and led to at least 38 deaths, according to statistics maintained by Johns Hopkins University and Medicine.

New Jersey’s first death from coronavirus was identified Tuesday as John Brennan, 69, a horse trainer from Little Ferry in Bergen County. He suffered from multiple pre-existing medical conditions, including diabetes, hypertension and emphysema, officials said.

State health officials said Wednesday they’ve identified two new positive cases of the coronavirus in New Jersey that could possibly be a result of “community spread."

Community spread is defined as person-to-person transmission without exposure to a confirmed case, health officials said. People in areas where there is community spread “are at elevated risk of exposure,” according to the federal Centers for Disease Control.

The coronavirus outbreak in New Jersey has moved most school districts to close or call for early dismissals to either clean facilities or plan with staff to switch to online instruction.

In addition, many colleges in New Jersey have announced that all classes will be held online for days or weeks. Princeton University expanded its precautions, telling students not to return for the rest of the semester.

State health officials also advised residents to stock up on a 14-day supply of food and medicine in the event they need to be quarantined.

Worldwide, more than 127,000 people have tested positive for coronavirus and the death toll has climbed above 4,718, according to CNN.com.
