TIMELINE: Tracking the Spread of the Coronavirus in New England

Here's what we know so far about the spread of COVID-19 in Massachusetts, Rhode Island, New Hampshire, Connecticut, Vermont and Maine

NBC Universal, Inc.

Thousands of people across New England have died of the new coronavirus and tens of thousands have tested positive, and efforts to mitigate the spread of the virus have caused massive changes to daily life across the region.

People have been ordered to stay home as much as possible, schools have moved online, businesses have closed and hospitals have braced for a huge influx of COVID-19 cases.

On Wednesday, Massachusetts' death toll topped 2,000, the highest in New England and fourth-highest nationwide. But the suffering has been felt regionwide -- Connecticut had more than 1,500 deaths, despite having half the number of people as its neighbor to the north.

Here's how the virus spread in New England:

Feb. 1: 1st Case in New England

The first case of COVID-19 was announced by Massachusetts health officials. The patient, a UMass Boston student who had recently traveled back to Boston from Wuhan, China, was the eighth diagnosis in the U.S. and the first on the East Coast.

The man is in his 20s and lives in Boston, according to the Massachusetts Department of Public Health. He sought medical attention soon after his return from China and quarantined at his home.

His "few close contacts" were identified and they were being monitored for any signs of symptoms.

After a college student was diagnosed with coronavirus, classmates want more answers from the University of Massachusetts.

Feb. 27: Boston Monitoring for Virus

The city of Boston said it was monitoring 34 people for signs of symptoms of the coronavirus, including Massachusetts' only confirmed case.

Officials said 33 people who each came through one of the 11 airports in the country that accept direct flights from China were being monitored. None of the 33, who were being monitored under CDC guidelines, had shown any symptoms.

The Connecticut State Colleges and Universities community also ordered all colleges and universities to immediately suspend or cancel internationally-sponsored trips to several countries out of concern for the virus.

Feb. 29: NH's First Patient Goes to Event in Vt.

When an employee at Dartmouth-Hitchcock Medical Center showed possible signs of symptoms, the person was examined and told to stay isolated. Instead, that person attended an invitation-only private party tied to Dartmouth College's business school in Vermont.

The following Tuesday, March 3, health officials in the state announced he was the first person in New Hampshire to test positive for coronavirus.

Dartmouth-Hitchcock Medical Center said it was not aware of any patients being exposed and had identified possible staff who could have been exposed.

The private event took place in the White River Junction's Engine Room, an event space across the river from New Hampshire, according to Vermont health officials. Dartmouth said it was a social event for the Tuck School of Business.

There were between 175 to 200 people at the event, the general manager of the Engine Room said, plus an additional seven staff members. The event space was sanitized, and the staff was told their risk of infection was low and that they could move forward with events.

There are now more than 125 confirmed or presumptive cases of coronavirus in the U.S., with some new reports in New England.

March 1: Two Positive Cases in RI

Rhode Island public health officials said they had identified the state's first and second presumptive positive cases of the coronavirus. The Rhode Island Department of Health announced that an unidentified man in his 40s and a teenager who both had traveled to Europe in mid-February tested positive for the virus.

Health officials said a third person in Rhode Island who was also on the trip to Europe was being tested for COVID-19.

Health officials announced a second person in close contact with him was also presumed to have COVID-19. Officials said the patient was isolated in his Grafton County home.

March 5: Biogen Meeting Starts Hot Spot

Massachusetts Gov. Charlie Baker said he believed a Tennessee man diagnosed with that state's first case of coronavirus who flew into Boston Logan International Airport was one of three people diagnosed with the virus after attending the meeting.

More than half of all attendees, about 100 people, would go on to test positive.
