9:18 p.m.: Trudeau's wife given all clear

Sophie Grégoire Trudeau, Canadian Prime Minister Justin Trudeau's wife, has been given a clean bill of health after previously testing positive for coronavirus.

She said in a Facebook post Saturday night that she was cleared by her doctor and Ottawa Public Health.

From the bottom of my heart, I want to say thank you to everyone who reached out to me with their well wishes. And to everyone who is suffering right now, I send you all my love.

"These are challenging times," she wrote. "I know it’s not easy to be alone -- we are all social beings, me included! But just because we’re increasing the physical distance between us doesn’t mean we have to do the same emotionally. From social media to a simple phone call, there are so many ways for us to stay connected while we’re apart and actually deepen our relationships."

Sophie tested positive for the virus March 13. Her husband said he never developed symptoms and continued working.

8:26 p.m.: Trump says he won't use enforceable quarantine in tristate

After threatening it earlier in the day, President Donald Trump now says he will not be using an enforceable quarantine in New York, New Jersey and Connecticut.

Instead Trump said he has asked the Centers for Disease Control and Prevention to issue a strong travel advisory "to be administered by the Governors, in consultation with the Federal Government."

The CDC later issued its advisory, writing in a release, "Due to extensive community transmission of COVID -19 in the area, CDC urges residents of New York, New Jersey, and Connecticut to refrain from non-essential domestic travel for 14 days effective immediately. This Domestic Travel Advisory does not apply to employees of critical infrastructure industries, including but not limited to trucking, public health professionals, financial services, and food supply."

The statement also said the governors of Connecticut, New York and New Jersey would have full oversight of implementing the advisory.

The governors of each of the three states -- all Democrats -- had reacted strongly against the proposed measure.

"That is not a quarantine, that is a lockdown," New York Gov. Andrew Cuomo said in an interview on CNN, likening the restriction to Wuhan, China. "I don’t believe it would be legal. I believe it would be illegal."

7:12 p.m.: US death toll surpasses 2,000

Cuomo's order applies to all hospitals in the state, both public and private.

Mount Sinai, which instituted a similar obstetrics ban, also will comply with the order.

Melissa DeRosa, secretary to Cuomo, announced the executive order would be issued on Saturday.

4:01 p.m.: Infant dies after contracting COVID-19 in Illinois

An infant was among the 13 new deaths reported in Illinois, the state's Department of Public Health reported.

"If you haven't been paying attention, this is your wake-up call," Dr. Ngozi Ezike, the director of the state's health agency, said. "We don't want to be one of the hotspots that the Surgeon General predicts Chicago could be.”

No details around the infant's death were provided.

Ezike said a full investigation was underway to determine the cause of death.

“There has never before been a death associated with COVID-19 in an infant.

The Department of Public Health noted that while older adults are at higher risk of severe illness, and more than 85% of deaths in Illinois are among individuals 60 years of age and older, people of all ages are suffering severe illness.

There were also an additional 465 new cases in Illinois, where there is a total of 3,491 confirmed cases.

2:14 p.m.: Trump strikes more assertive tone on GM manufacturing ventilators

President Donald Trump said he had compelled General Motors to manufacture ventilators, after saying the day before that "maybe we won't even need the full activation," referring to using the Defense Protection Act.

"This week, I invoked the Defense Production Act to compel General Motors to carry out federal contracts for ventilators and I think they're going to do a great job. I have to say that," Trump said in his speech at Norfolk Naval Base.

The president also said that FEMA has "shipped or delivered" 11.6 million N-95 respirators, 26 million surgical masks and 5.2 million face shields.

2:08 p.m.: New cases in Italy continue to slow, but deaths top 10,000

It was the lowest percentage increase to date in the country. The total number of cases in Italy is now at least 92,472, health officials said.

In the province of Bergamo, the hardest-hit province, there was a nearly 50% drop in new reported cases, from Friday's 602 to Saturday's 289.

1:44 p.m.: UN to donate 250,000 masks to NYC

The United Nations will donate 250,000 protective face masks to New York City, an area now considered the epicenter of the pandemic.

UN Secretary General António Guterres said the masks would go to medical professionals in the city who have been "working courageously, selflessly, and tirelessly in response to the spread of COVID-19 across the boroughs in the hope that they play some small role in saving lives."

The U.N. and U.S. Mission personnel are working with Mayor Bill de Blasio's office to quickly get the masks to medical facilities in New York City.

12:46 p.m.: Trump considering enforceable quarantine in New York, New Jersey and Connecticut

President Donald Trump said he may announce an enforceable quarantine in the New York, New Jersey and Connecticut areas.

Trump noted that he "doesn't want to do it, but may have to."

“There's a possibility that sometime today we'll do a quarantine, short-term two weeks, on New York, probably New Jersey, certain parts of Connecticut,” Trump told reporters on the South Lawn.

The president said that he would restrict travel from those areas because "they're having problems down in Florida, a lot of New Yorkers going down, we don't want that." He later said such a quarantine would not apply to truckers from outside of New York who are making deliveries or traveling through the state.

"It won't affect trade in anyway," Trump said.

New York Gov. Andrew Cuomo later responded to the possibility, saying he had not spoken to the president about such a measure and did not know what it would mean.

Connecticut Gov. Ned Lamont also issued a statement, saying, "Our state has already called on residents to stay at home. Further, if interstate travel is absolutely necessary, our state has directed travelers to self-quarantine to prevent against further transmission of the virus." Lamont said that he looked forward to speaking to the president directly, "because confusion leads to panic."

Cuomo did say there was a bit of good news: new hospitalizations and new ICU admissions went down in the last 24-hour period. He cautioned that one day does not prove a trend and the situation certainly could go the other way.

There were 372 people admitted in to an ICU Friday and 172 admitted Saturday. For new hospitalizations, the number Friday was 1,154 and 847 for Saturday.

“The overall line is still up,” Cuomo said. “This is good news on a one day number.”

10:01 a.m.: Nearly 200 US cities lack emergency equipment: Report

Nearly 200 cities in the United States do not have an adequate supply of tests kits or face masks for medical personnel and first responders, including police, fire, and EMTs, according to a report from the U.S. Conference of Mayors.

About 88% of cities of the cities surveyed, or 186 cities, don't have enough personal protective equipment (PPE) other than face masks to protect the front-line workers, according to the report.

The staggering statistics "illustrates the scope and severity of the need for COVID-19 emergency equipment in this nation's cities," according to a letter from the conference's executive director, Tom Cochran.

One-hundred and thirty-one states have reported receiving no emergency equipment from their states, while 84% of those who are receiving help say it is not adequate for their needs.

The report estimates that across the cities surveyed there is a need for 28.5 million face masks, 24.4 million PPE items, 7.9 million test kits, and 139,000 ventilators.

There were 213 cities in 40 states that participated in the survey.

"It is abundantly clear that the shortage of essential items such as face masks, test kits, personal protective equipment, ventilators and other items needed by health and safety personnel has reached crisis proportions in cities across the country," Cochran said in his letter.

9:53 a.m.: More than 8,000 new cases, 832 new deaths in Spain

Spain reported 8,189 new cases of novel coronavirus in the last 24 hours, putting the total number of cases at 72,248, according to the Health Ministry.

8:55 a.m.: German Aerospace Center to make masks

The German Aerospace Center will make medical equipment using its 3D printers, according to a statement from the agency.

The printers were tested and can successfully produce protective masks and valves for respirators, the statement read.

The German Aerospace Center had been asked by the European Commission to help in producing much needed medical equipment as the world scrambles to combat the pandemic.

The most powerful printer can produce up to 10 protective masks or 15 valves for ventilators per day, according to the agency. However, it's possible to increase the quantity through networking with other institutes and facilities.

6:00 a.m.: Lockdown leads to drop in pollution in Europe

Air pollution has dropped significantly across Europe as lockdowns have been adopted and residents are told to stay home, according to the European Space Agency.

Satellite images from the Copernicus Sentinel-5P show the drop in nitrogen dioxide concentrations, which coincides with the quarantine measures, according to the agency.

The most significant drops were in Milan, Paris and Madrid.

Scientists from the Royal Netherlands Meteorological Institute (KNMI) have been using data from the satellite to monitor both weather and pollution over Europe. The images show the nitrogen dioxide concentrations from March 14 to March 25, comparing it to the averages from last year.

"By combining data for a specific period of time, 10 days in this case, the meteorological variability partly averages out and we begin to see the impact of changes due to human activity," Henk Eskes, from KNMI, said in a statement.

Other countries are also being monitored, including the Netherlands and the United Kingdom. Scientists have said that right now there is a larger variability because of changing weather conditions, making it more difficult to observe any changes.

4:43 a.m.: Rhode Island targeting New York travelers

A day after announcing all vehicles with New York license plates will be pulled over by state police and travelers informed they must quarantine if they are staying in the state, Rhode Island Gov. Gina Raimondo announced that the National Guard would go door-to-door to make sure New Yorkers are following orders.

"We have a pinpointed a risk that we need to address, and that risk is New York City," Raimondo said Friday during her daily coronavirus media briefing. She said the 14-day quarantine for New York travelers is a law and will be enforced, "it's not a suggestion."

Members of the National Guard will be stationed at bus and train stops, as well as airports to collect personal information form travelers when they arrive. State police officers are doing the same for vehicles they pull over. With that information, Raimondo said authorities would go hotels, vacation homes and any type of residence to keep track of New York travelers.

All these measures, she said, are designed to let the state have time to get ready for the spread of COVID-19. If Rhode Island were to have an outbreak right now, she said the state and its healthcare system would be overwhelmed.

"We are not ready for a surge of cases," Raimondo said.

New York City currently has at least 26,000 diagnosed cases of COVID-19, with 450 deaths. There are more than 44,000 cases in New York state. As of Friday, only 28 of the 203 diagnosed coronavirus cases in Rhode Island have required hospitalization. The state has no reported COVID-19 deaths.
