Further COVID-19 testing of Navy sailors from the USS Theodore Roosevelt shows the number of positive cases has increased again in the past few days, from 615 to 678, military officials said Monday.

Ninety-four percent of the roughly 4,800-member crew has been tested so far. About 3,900 of them have tested negative.

The aircraft carrier was caught in the middle of a controversy after its captain, Brett Crozier, sounded the alarm of an outbreak on board; he was relieved of his duty earlier this month. The military said last week that one crew member died last week from coronavirus-related complications.

The commander of Iran's Revolutionary Guard Corps unveiled a handheld device on Wednesday that he said could detect coronavirus almost instantly, but Iranian scientists have rejected the claim and other government officials have distanced themselves.

GENEVA — The World Health Organization chief warned Monday that “the worst is yet ahead of us” in the coronavirus outbreak, reviving the alarm just as many countries ease restrictive measures aimed at reducing its spread.

WHO Director-General Tedros Adhanom Ghebreyesus didn’t specify why he believes the outbreak that has infected some 2.5 million people and killed over 166,000 could get worse. He and others, however, have previously pointed to the likely future spread of the illness through Africa, where health systems are far less developed.

A video that has garnered over 1 million views on social media shows endangered penguins roaming the empty streets of Cape Town, South Africa, during the country's COVID-19 lockdown. They're not the only ones.

New York Gov. Andrew Cuomo said Monday that an additional 478 people have died due to COVID-19, not including presumed cases, bringing the total number of deaths to 14,347. 

It's the the first time since April 2 that the single-day death toll dropped below 500 people, according to The New York Times.

During his daily news conference, Cuomo also called for a 50 percent pay bonus for first responders as part of a “hazard pay” for their work amid the coronavirus crisis. He also announced a plan to distribute hand sanitizer as well as over 500,000 cloth masks to public housing communities so that each resident has at least one mask.

Cuomo also discussed President Donald Trump's insistence that states are responsible for the widespread testing needed ease lockdown restrictions, saying that he agreed governors should take the lead but stressed the need for the federal government to coordinate around critical lab supplies. 

Russian President Vladimir Putin said in a meeting with epidemiologists Monday that his country has not yet reached the peak of coronavirus infections and deaths.

"Therefore we must do everything to flatten this peak," Putin said. Russia has around 47,000 confirmed cases and more than 400 reported deaths.

Meanwhile, Russia's defense ministry has quarantined 15,000 troops after they took part in rehearsals for the country's now-postponed Victory Day celebrations, which had been scheduled to take place May 9.

Video footage showed the thousands of soldiers in tight formation without masks or other protective equipment. All hardware used in the rehearsals will be sanitized before being returned to its bases, the ministry said.

Facebook has removed events in a handful of states planning protests against stay-at-home measures meant to stop the spread of the coronavirus.

The events, which were planned in California, Nebraska and New Jersey, violated protective measures imposed by governors, Facebook said.

"Unless government prohibits the event during this time, we allow it to be organized on Facebook,” a Facebook spokesperson said in a statement. “For this same reason, events that defy government's guidance on social distancing aren’t allowed on Facebook."

The removals were first reported by The Washington Post. Many other protest events remain active on Facebook, with some slated for Monday.

Karla Duarte, 16, was released from Cohen Children’s Medical Center after a nearly month-long battle with COVID-19, the disease caused by coronavirus. She was hospitalized on March 29 after experiencing symptoms for about a week and was intubated on April 2 after her condition worsened, according to Northwell Health. 

On April 4, Duarte was put on a VV ECMO machine, which is an invasive therapy where blood is removed from the body, passed through an artificial lung to remove carbon dioxide and add oxygen and then returned to the body. According to Northwell Health, this is the first time this treatment has been used on a minor on a ventilator for COVID-19 at Cohen Children’s Medical Center. 

Miraculously, the treatment was successful. Duarte was removed from ECMO on April 10 and extubated on April 15. She continued to quickly recover and was released from the hospital on April 19.

“Her successful treatment and use of ECMO would not have been possible without the extraordinary multidisciplinary effort by the entire Cohen Children’s team, including PICU nurses and physicians, ECMO nurse specialists, perfusionists, and surgeons,” said Dr. James Schneider in a statement released by Northwell Health.
