European nations tightened restrictions designed to check the spread of the coronavirus, with Germany banning gatherings of more than two people, Spain moving to extend a state of emergency and Italy ordering a halt to domestic travel.

While Germany stopped short of confining people to their homes, it will prevent citizens meeting in groups for at least two weeks, with only families and people sharing a home exempt, Chancellor Angela Merkel said Sunday. Restaurants will be closed except for takeout and delivery services.

“No one wants to stand before the people and discuss such rules,” Merkel said at a news conference in Berlin after a video conference with regional leaders.

At least five downtown Denver hotels have closed temporarily to stem the coronavirus spread, and the statewide industry is bracing for a hit that could lead to as many as 72,000 job losses in a sector that produces a $13.4 billion annual gross domestic product statewide.

While only a handful of mountain resorts had shut down by early this week, that number has ballooned in recent days as hotels across the metro region are reporting vacancy levels below 10% during a month many had predicted would be record-setting, Colorado Hotel and Lodging Association President/CEO Amie Mayhew said. Among those that have announced they will shutter until May 11 or 12 are the Grand Hyatt Denver, the Oxford Hotel, the Crawford Hotel and The Maven Hotel at Dairy Block.

All of those except for the Grand Hyatt are operated by Sage Hospitality Group of Denver, whose CEO, Walter Isenberg, issued a letter Thursday saying he’d made “the very difficult decision to temporarily suspend business operations at a portion of our hotels and restaurants in order to protect the health and safety of our guests, our associates and our communities.”

Dr. Ezekiel Emanuel, an American oncologist and bioethicist who is senior fellow at the Center for American Progress as well as Vice Provost for Global Initiatives at the University of Pennsylvania and chair of the Department of Medical Ethics and Health Policy, said on MSNBC on Friday, March 20, that Tesla and SpaceX CEO Elon Musk told him it would probably take 8–10 weeks to get ventilator production started at his factories (he’s working on this at Tesla and SpaceX).

I reached out to Musk for clarification on that topic and he replied that, “We have 250k N95 masks. Aiming to start distributing those to hospitals tomorrow night. Should have over 1000 ventilators by next week.” With medical supplies such as these being one of the biggest bottlenecks and challenges at the moment in the COVID-19 response in the United States (as well as elsewhere) — something that is already having a very real effect on medical professionals and patient care — the support will surely be received with much gratitude. That said, while there has been much attention put on the expected future need for ventilators, very few places reportedly have a shortage of them right now. In much greater need at the moment are simpler supplies like N95 masks, which must be why Tesla/SpaceX is providing 250,000 of them.

Dr. Emanuel also said in the segment of MSNBC’s “Morning Joe” he was on that we probably need 8–12 weeks (2–3 months) of social distancing in the US in order to deal with COVID-19 as a society. However, he also expects that the virus will come back and we’ll basically have a roller coaster of “social restrictions, easing up, social restrictions, easing up … to try to smooth out the demand on the health care system.”

“Infusions of antibody-laden blood have been used with reported success in prior outbreaks, including the SARS epidemic and the 1918 flu pandemic.”

With a vaccine for COVID-19 still a long way from being realized, Johns Hopkins immunologist Arturo Casadevall is working to revive a century-old blood-derived treatment for use in the United States in hopes of slowing the spread of the disease.

With the right pieces in place, the treatment could be set up at Johns Hopkins University in Baltimore within a matter of weeks, Casadevall says.

As they increasingly log on from home, Americans are having to meld their personal technology with professional tools at unprecedented scale. For employers, the concern isn’t just about capacity, but also about workers introducing new potential vulnerabilities into their routine — whether that’s weak passwords on personal computers, poorly secured home WiFi routers, or a family member’s device passing along a computer virus.


The dramatic expansion of teleworking by US schools, businesses and government agencies in response to the coronavirus is raising fresh questions about the capacity and security of the tools many Americans use to connect to vital workplace systems and data.

At one major US agency, some officials have resorted to holding meetings on iPhone group calls because the regular conference bridges haven’t always been working, according to one federal employee. But the workaround has its limits: The group calls support only five participants at a time, the employee noted.

“Things have worked better than I anticipated, but there are lots of hiccups still,” said the employee, who spoke on condition of anonymity because he is not authorized to speak on the record.
