With new coronavirus cases confirmed Tuesday, the United States now has more than 1,000 infected people.
Turbulent trading continued to roll Wall Street, and anxieties over the coronavirus failed to subside with an increase in U.S. deaths and New York Gov. Andrew Cuomo ratcheting up protective measures in his state.
Cuomo deployed National Guard troops to a health department command post in New Rochelle, a suburb of New York City where health officials have reported at least 108 cases of COVID-19 in the area. While there have been no reported deaths in New York, neighboring New Jersey announced its first one: a man in his 60s in Bergen County.
The markets remained volatile a day after the Dow Jones shed 2,000 points — Wall Street's worst day since the financial crash of 2008. The Dow rallied before giving up most of its gain Tuesday afternoon.
The coronavirus outbreak has continued to rattle Italy, which extended the containment measures already in place in northern regions to the entire country, which has confirmed more than 10,140 cases. The death toll in the country stands at more than 630 people.

South Dakota has 5 presumptive cases, including one person who has died
Five presumptive cases of COVID-19 have been identified in South Dakota, the governor said Tuesday. That count includes one person who died, but it is unclear what killed that patient, she said.
"We have one person that has passed away that had underlying medical conditions, and we will continue to wait for a medical examination to see if the virus had anything to do with that — although we do not have confirmation that that is the reason that the patient is deceased," Gov. Kristi Noem said at a news conference. The person who died was a man in his 60s.
The five cases, which are not in any single community, are the first presumptive cases for South Dakota. Cases are called presumptive when local tests come back positive but when CDC testing has not yet confirmed that result.
If the death was caused by COVID-19, the death would mark the 31st in the United States, according to a count of reported cases by NBC News. The four other people with presumptive positive cases are at home and contact tracing is being done, the governor said.
22 more deaths in mainland China, bringing total to 3,158
China's National Health Commission reported 22 new deaths, all of them in Hubei Province, bringing the total across the mainland to 3,158 as of Wednesday morning.
The coronavirus outbreak began in Hubei Province, which is where the city of Wuhan is located. There have been more than 80,700 confirmed cases reported in mainland China, according to the health commission.
There are outbreaks in other countries, with some of the highest number of cases outside mainland China being reported in South Korea, Italy and Iran. The United States has more than 1,000 confirmed or presumptive cases, according to a count of reports by NBC News. Thirty people have died in the U.S.
Person at New Orleans journalism conference tests positive
Someone who attended a journalism conference in New Orleans this month has tested positive for the novel coronavirus, organizers said Tuesday.
The attendee at the NICAR20 conference last week has mild symptoms and is expected to make a full recovery, the nonprofit organization Investigative Reporters and Editors said in a statement.
The person is self-quarantining at home for 14 days. The case is being considered a presumptive positive because it has not been confirmed by the Centers for Disease Control and Prevention.
"Based on the onset of the limited symptoms, they could have contracted the virus either before, during or after the conference," IRE said. The organization said the person as well as the organization is notifying anyone who had close contact or who attended a class with that person.
Three TSA officers at San Jose airport test positive
Three security officers at the international airport in San Jose, California, have tested positive for the novel coronavirus that causes the COVID-19 illness, the TSA said Tuesday.
"The officers are receiving medical care and all TSA employees they have come in contact with over the past 14 days are quarantined at home,” The Transportation Security Administration said in a statement to NBC Bay Area.
The officers worked at Mineta San Jose International Airport, which is in Santa Clara County.
"Screening checkpoints remain open and the agency is working with the CDC, as well as the California Department of Public Health and the Santa Clara County Public Health Department to monitor the situation as well as the health and safety of our employees and the traveling public," the TSA said.
Santa Clara County has seen 45 positive tests, and the increase in cases that could be instances of community spread prompted health officials there to ban mass gatherings of 1,000 or more people for three weeks. One person died in Santa Clara County Monday morning, the health department said.
More than 1,400 have disembarked from Grand Princess cruise ship
More than 1,400 people have disembarked from the Grand Princess cruise ship, the vessel that was delayed off the coast of California after it was linked to the coronavirus illness COVID-19, the cruise company said Tuesday evening.
There were 3,533 people aboard the ship — including 2,422 guests and 1,111 employees — when it returned from Hawaii to California last week, the cruise company has said. Princess Cruises said that as of 7 p.m. Tuesday, 1,406 people had disembarked.
The ship was delayed for testing after several people from a voyage in mid-February tested positive for COVID-19, including one who died last week in Placer County. On Friday, tests that were flown to the ship came back positive for 21 people aboard, which included 19 crew and two passengers.
On Monday people began disembarking, and California officials have said that 407 people disembarked then.
Officials have said that those disembarking would be subject to a 14-day quarantine, many of them at military bases. Disembarking all of the passengers "will be a multiple day process," Princess Cruises said.
