As the coronavirus pandemic continues to affect people all over the globe, Airbnb is stepping up with a plan to offer free or subsidized housing to people working on the disease's front lines, namely health care professionals, emergency workers and relief personnel. From a report: The company announced today that it will provide "free or subsidized housing" for 100,000 people working as frontline healthcare, relief for first response professionals focused on stemming the COVID-19 crisis. Airbnb's effort will work by allowing Hosts on its platform to opt-in to making their space available, with any fees that Airbnb would normally charge for using its platform waived for those who participate.

sciencehabit shares a report from Science Magazine: The $2 trillion stimulus package that the U.S. Senate is working to approve today is aimed at helping the country cope with the massive impact of the coronavirus pandemic. But it also includes at least $1.25 billion for federal research agencies to support scientists trying to better understand coronavirus disease 2019 (COVID-19). In addition, it extends a financial hand to universities that have shut down because of the pandemic, some of which could go to support research that has been disrupted.

Details of the legislation have yet to emerge after Republican and Democratic leaders in Congress worked out their differences in negotiations that ran into the early morning. But a 22-page summary (PDF) released by the Senate Appropriations Committee this morning contains these highlights:

- The National Institutes of Health would receive $945 million for "vaccine, therapeutic, and diagnostic research" on COVID-19 as well as on "the underlying risks to cardiovascular and pulmonary conditions."
- The National Science Foundation would receive $76 million to supplement an ongoing program that allows scientists to jump into the field for pilot studies on all manner of natural disasters.
- The Department of Energy's Office of Science would get $99.5 million to cover the additional costs of operating user facilities at its national laboratories, including support for equipment and staff.
- The U.S. Forest Service would get $3 million to "reestablish experiments impacted by travel restrictions" stemming from the pandemic, including an ongoing forest inventory.

In addition, three research agencies would receive a total of $86 million "to support continuity of operations" affected by COVID-19. NASA would receive $60 million for the costs of rescheduling scientific missions, the National Oceanic and Atmospheric Administration would get $20 million to supplement "life and property related services" within its National Weather Service, and the National Institute of Standards and Technology would receive $6 million to support "research and measurement science" aimed at developing better diagnostics and testing of the coronavirus.

Nuclear scientists in Austria are closing in on new coronavirus testing kits that could dramatically lower the cost and time it takes to diagnose people for the disease. From a report: With Covid-19 tests in short supply in many places, some individuals have turned to private laboratories that can genetically detect the pathogen. That process, called reverse transcription-polymerase chain reaction, or RT-PCR, can cost as much as $400 in some private facilities. But the International Atomic Energy Agency expects it can produce Covid-19 tests costing as little as 10 euros ($10.83) that yield a diagnosis within hours, according to an spokesperson, who said the IAEA kits are close to being shipped. While the IAEA's individual tests may top out at 15 euros a person, countries will still need laboratories to process the results. Setting up a new facility from scratch can cost as much as 100,000 euros, according to the agency. The IAEA's lab outside Vienna has previously developed kits testing for Ebola, Zika and African Swine Fever. Fourteen countries in Africa, Asia and Latin America asked the agency's scientists earlier this month to help them ramp up testing. The effort drew an extra $5 million of funding on Tuesday from the U.S. State Department.

People are having to use videolinks to say their last goodbyes to dying relatives with Covid-19 because hospitals are curtailing visits to prevent spread of the virus. From a report: In a sad scene that is increasingly being played out out across the country, in the early hours of Tuesday morning a patient with coronavirus was taken off a ventilator at a hospital in south-east London. His wife and two children were unable to be with him but watched at home via videolink, after agreement from staff in the intensive treatment unit.

Coronavirus RNA survived for up to 17 days aboard the Diamond Princess cruise ship, lasting far longer on surfaces than previous research has shown, according to new data published this week by the Centers for Disease Control and Prevention. From a report: The study examined the Japanese and U.S. government efforts to contain the COVID-19 outbreaks on the Carnival-owned Diamond Princess ship in Japan and the Grand Princess ship in California. Passengers and crew on both ships were quarantined on board after previous guests, who didn't have any symptoms while aboard each of the ships, tested positive for COVID-19 after landing ashore. The RNA, the genetic material of the virus that causes COVID-19, "was identified on a variety of surfaces in cabins of both symptomatic and asymptomatic infected passengers up to 17 days after cabins were vacated on the Diamond Princess but before disinfection procedures had been conducted," the researchers wrote, adding that the finding doesn't necessarily mean the virus spread by surface. The CDC said researchers couldn't "determine whether transmission occurred from contaminated surfaces," and that further study of COVID-19's spread through touching surfaces on cruise ships was warranted.

Amazon said on Tuesday that it is temporarily discontinuing accepting orders for "lower-priority" products in India and prioritizing servicing urgent items such as household staples, health care, and personal safety products as the e-commerce player -- along with several of its competitors -- grapples with coronavirus outbreak in one of its key overseas markets. From a report: "To serve our customers' most urgent needs while also ensuring safety of our employees, we are temporarily prioritizing our available fulfilment and logistics capacity to serve products that are currently critical for our customers such as household staples, packaged food, health care, hygiene, personal safety and other high priority products," the American e-commerce giant said in a statement. "This also means that we have to temporarily stop taking orders and disable shipments for lower-priority products," it added. Understandably, the company said it did not have a timeline to share for how long this new measure would last. Amazon has taken a similar approach in the U.S. and Italy. The move, which goes into effect today, comes as nearly every Indian state has imposed a lockdown to prevent the spread of COVID-19.

An anonymous reader quotes a report from ProPublica: A nationwide shortage of two drugs touted as possible treatments for the coronavirus is being driven in part by doctors inappropriately prescribing the medicines for family, friends and themselves, according to pharmacists and state regulators. Demand for chloroquine and hydroxychloroquine surged over the past several days as President Donald Trump promoted them as possible treatments for the coronavirus and online forums buzzed with excitement over a small study suggesting the combination of hydroxychloroquine and a commonly used antibiotic could be effective in treating COVID-19.

"It's disgraceful, is what it is," said Garth Reynolds, executive director of the Illinois Pharmacists Association, which started getting calls and emails Saturday from members saying they were receiving questionable prescriptions. "And completely selfish." Reynolds said the Illinois Pharmacists Association has started reaching out to pharmacists and medical groups throughout the state to urge doctors, nurses and physician assistants not to write prescriptions for themselves and those close to them. "We even had a couple of examples of prescribers trying to say that the individual they were calling in for had rheumatoid arthritis," he said, explaining that pharmacists suspected that wasn't true. "I mean, that's fraud." In one case, Reynolds said, the prescriber initially tried to get the pills without an explanation and only offered up that the individual had rheumatoid arthritis after the pharmacist questioned the prescription. In a bulletin to pharmacists on Sunday, the state association wrote that it was "disturbed by the current actions of prescribers" and instructed members on how to file a complaint against physicians and nurses who were doing it. It's important to note that there is little evidence that the drugs work to treat coronavirus, although clinical trials are underway to find out.

The report mentions a man in his 60s who died after ingesting a version of the chloroquine commonly used to clean fish tanks. "The man, who thought he might have COVID-19, took a small amount of the substance in a misguided effort to treat his symptoms," reports ProPublica. "His wife was also hospitalized after taking the substance but survived."

Ford announced today that it's partnering with 3M and GE to build respirators, ventilators and face shields for front-line healthcare workers and COVID-19 patients. TechCrunch reports: Its efforts include building Powered Air-Purifying Respirators (PAPRs) with partner 3M, including a new design that employs existing parts from both partners to deliver effectiveness and highly scalable production capacity. Ford says that it's also going to be building face shields, leaning on its 3D printing capabilities, with an anticipated production rate of more than 100,000 units per week. The company has designed a new face shield, which will be tested with the first 1,000 units this week at Detroit Mercy, Henry Ford Health Systems and Detroit Medical Center Sinai-Grace Hospitals in Michigan to evaluate their efficacy. Provided they perform as planned, Ford anticipates scaling to building 75,000 by end of week, with 100,000 able to be made in one of the company's Plymouth, Mich. production facilities each week thereafter.

The automaker is also going to be working with GE on expanding production capacity for GE Healthcare's ventilator, with a simplified design that should allow for higher-volume production. That's part of a response to a U.S. government request for more units to support healthcare needs, the company said. On top of its U.S.-focused ventilator project with GE, Ford is also working on a separate effort to spin up ventilator production targeting the U.K. based on a request for aid from that country's government, and it's also shipping back 165,000 N95 respirator masks that were sent by the company from the U.S. to China earlier this year, since the need for that equipment is now greater back in the U.S., the company said, and China's situation continues to improve. "The PAPRs that Ford is building, for instance, will use off-the-shelf components from the automaker's F-150 truck's cooled seating, as well as 3M's existing HEPA filters," the report adds. "These respirators could potentially offer significant advantages in use compared to N95s, since they are battery-powered and can filter airborne virus particles for up to eight hours on a single, swappable standard power tool battery pack worn at the waist."

Indian Prime Minister Narendra Modi said on Tuesday the government would impose a nationwide lockdown from midnight for 21 days to stem the spread of the coronavirus. "There will be a total ban on venturing out of your homes," Modi said in a televised address.

Communities living in warmer places appear to have a comparative advantage to slow the transmission of coronavirus infections, according to an early analysis by scientists at the Massachusetts Institute of Technology. From a report: The researchers found that most coronavirus transmissions had occurred in regions with low temperatures, between 37.4 and 62.6 degrees Fahrenheit (or 3 and 17 degrees Celsius). While countries with equatorial climates and those in the Southern Hemisphere, currently in the middle of summer, have reported coronavirus cases, regions with average temperatures above 64.4 degrees Fahrenheit (or 18 degrees Celsius) account for fewer than 6 percent of global cases so far. "Wherever the temperatures were colder, the number of the cases started increasing quickly," said Qasim Bukhari, a computational scientist at M.I.T. who is a co-author of the study. "You see this in Europe, even though the health care there is among the world's best."

sciencehabit writes: Science Magazine has learned that researchers across the U.S. are euthanizing thousands of lab mice in anticipation of a shortage of workers who can care for them. Some scientists have had to sacrifice half or more of their colonies, potentially resulting in the loss of months or years of work. "I was staring at my mice one by one and deciding who lives and who dies," says one researcher. "It was really rough." At the moment, Science has not seen evidence that larger animals such as cats, dogs, or monkeys are being proactively euthanized. That will likely remain the case. Unlike larger animals, mice breed quickly and must be used quickly. And because they comprise about 95% of all research animals, they suck up the most money and time.

An anonymous reader quotes a report from Bloomberg: President Donald Trump is considering easing health directives that prevent the spread of the coronavirus in an attempt to contain economic fallout. A new analysis suggests that those measures are helping to save hundreds of thousands of lives. Economists led by Northwestern University's Martin Eichenbaum wrote that keeping social-distancing measures in place before the number of new virus cases declines -- in other words, before a peak in the infection rate -- could limit infections and prevent as many as 600,000 additional U.S. deaths. While the economic damage is deeper when optimal health measures are taken, a recession is unavoidable even without them, as infected people would stay at home to recover and millions die, the report shows.

Under a worst-case scenario, with stores remaining open and no social isolation policies, as many as 215 million Americans could become infected and 2.2 million could die from the spread of the virus, the economists' data shows. That's based on an estimate from German Chancellor Angela Merkel that up to 70% of that country's population could become infected without a vaccine. It also matches the worst-case global estimate from Harvard University epidemiology professor Marc Lipsitch.

With medical supplies strained by the coronavirus outbreak, health care professionals and technologists are coming together online to crowdsource repairs and supplies of critical hospital equipment. From a report: Doctors, hospital technicians and 3D-printing specialists are also using Google Docs, WhatsApp groups and online databases to trade tips for building, fixing and modifying machines like ventilators to help treat the rising number of patients with COVID-19, the disease caused by the coronavirus. The efforts come as supply shortages loom in one of the biggest challenges for health care systems around the world. "We have millions of health care workers around this country who are prepared to do battle against this virus, but I am concerned there are a couple of areas of supplies they need to fight that virus as effectively as possible," Dr. Peter Slavin, president of Massachusetts General Hospital in Boston, told NBC News, noting that protective equipment, including surgical masks and eye protection, was in particularly short supply. "We wouldn't want to send soldiers to war without helmets and armor," he said. "We don't want to do the same with our health care workers."

The American Hospital Association says COVID-19 could require the hospitalization of 4.8 million patients, 960,000 of whom would need ventilators. As the demand for the equipment surges, making timely repairs will be critical to saving lives. New York Mayor Bill de Blasio warned Friday that the city could run out of basic medical supplies in as little as two weeks. 3D printing, a relatively new and niche technology that can create everything from houses to tiny and complex structures from raw materials, has remained mostly on the fringes of the manufacturing and health care sectors. But the coronavirus has suddenly made it a crucial resource. On Thursday, Slavin called on people with 3D printers to help make protective masks for hospital staff.

UK Prime Minister Boris Johnson announced strict measures to combat the spread of the coronavirus. He says a "huge national effort" has been needed to halt the spread, adding: "there will come a moment when no health service in the world could possibly cope because there won't be enough ventilators, enough intensive care beds, enough doctors and nurses." Non-essential businesses will be closed and citizens are being ordered to stay in their homes. They can only leave for the following "very limited purposes": shopping for basic necessities; one form of exercise a day alone or with members of your household; any medical need, to provide care or to help a vulnerable person; and/or traveling to and from work, but only where this is absolutely necessary and cannot be done from home.

"That's all -- these are the only reasons you should leave your home," says Johnson. "You should not be meeting friends. If your friends ask you to meet, you should say No. You should not be meeting family members who do not live in your home. You should not be going shopping except for essentials like food and medicine -- and you should do this as little as you can. And use food delivery services where you can." The police will be able to take action through fines and dispersing gatherings. The lockdown restrictions will be looked at again in three weeks to determine if they'll be relaxed or not.

India is turning to WhatsApp, the most popular app in the country, to create awareness about the coronavirus pandemic and has urged social media services to tackle the spread of misinformation on their platforms. From a report: Narendra Modi, India's Prime Minister, said on Saturday that citizens in the country can text a WhatsApp bot -- called MyGov Corona Helpdesk -- to get instant authoritative answers to their coronavirus queries such as the symptoms of the viral disease and how they could seek help. An individual is required to text +919013151515 to connect to the bot. The bot was built by Mumbai-based firm Haptik Technologies, which local telecom giant Reliance Jio acquired last year, and the information is being provided by the nation's Ministry of Health.

The number of "silent carriers" -- people who are infected by the new coronavirus but show delayed or no symptoms -- could be as high as one-third of those who test positive, according to classified Chinese government data seen by the South China Morning Post. An anonymous reader writes: That could further complicate the strategies being used by countries to contain the virus, which has infected more than 300,000 people and killed more than 14,000 globally. More than 43,000 people in China had tested positive for Covid-19 by the end of February but had no immediate symptoms, a condition typically known as asymptomatic, according to the data. They were placed in quarantine and monitored but were not included in the official tally of confirmed cases, which stood at about 80,000 at the time. Scientists have been unable to agree on what role asymptomatic transmission plays in spreading the disease. A patient usually develops symptoms in five days, though the incubation period can be as long as three weeks in some rare cases.

South Korea "has emerged as a sign of hope and a model to emulate," reported Nature earlier on Tuesday. "The country of 50 million appears to have greatly slowed its epidemic; it reported only 74 new cases today, down from 909 at its peak on 29 February." And it has done so without locking down entire cities or taking some of the other authoritarian measures that helped China bring its epidemic under control. "South Korea is a democratic republic, we feel a lockdown is not a reasonable choice," says Kim Woo-Joo, an infectious disease specialist at Korea University. South Korea's success may hold lessons for other countries — and also a warning: Even after driving case numbers down, the country is braced for a resurgence.

Behind its success so far has been the most expansive and well-organized testing program in the world, combined with extensive efforts to isolate infected people and trace and quarantine their contacts. South Korea has tested more than 270,000 people, which amounts to more than 5200 tests per million inhabitants — more than any other country except tiny Bahrain, according to the Worldometer website. The United States has so far carried out 74 tests per 1 million inhabitants, data from the U.S. Centers for Disease Control and Prevention show. South Korea's experience shows that "diagnostic capacity at scale is key to epidemic control," says Raina MacIntyre, an emerging infectious disease scholar at the University of New South Wales, Sydney. "Contact tracing is also very influential in epidemic control, as is case isolation," she says...

Legislation enacted since [2015] gave the government authority to collect mobile phone, credit card, and other data from those who test positive to reconstruct their recent whereabouts. That information, stripped of personal identifiers, is shared on social media apps that allow others to determine whether they may have crossed paths with an infected person... There are 43 drive-through testing stations nationwide, a concept now copied in the United States, Canada, and the United Kingdom. In the first week of March, the Ministry of the Interior also rolled out a smartphone app that can track the quarantined and collect data on symptoms.


"We hope our experience will help other countries control this COVID-19 outbreak," Kim tells Nature. And Reuters reports that in the five days since the article was published, South Korea has still kept new infections around a low 100 or less each day -- for 12 consecutive days -- compared with the peak of 909 new cases reported on February 29.

Reuters adds that though South Korea has experienced 8,961 cases, on Monday it reported its lowest daily number yet for new cases -- 64. And on the same day, "257 patients were released from hospitals where they had been isolated for treatment, the KCDC said.

"South Korea posted more recoveries than new infections on March 13 for the first time since its first case was confirmed on January 20."

"White House officials are asking tech companies for more insight into our social networks and travel patterns," reports Wired, noting that Facebook even "created a disease mapping tool that tracks the spread of disease by aggregating user travel patterns." And Clearview AI "says it is in talks with public officials to use its software to identify anyone in contact with people who are infected." Such efforts clash with people's expectations of privacy. Now, there's a compelling reason to collect and share the data; surveillance may save lives. But it will be difficult to draw boundaries around what data is collected, who gets to use it, and how long the collection will continue...

"What's really important is for the government to be really clear in articulating what specific public health goals it's seeking to accomplish," said Kelsey Finch, senior counsel at the Future of Privacy Forum, an industry-backed group focused on tech policy. "And how it's limiting the collection of personal data to what's necessary to achieve those very specific goals, and then making sure that there are appropriate privacy safeguards put in place before data starts to change hands...."

Some privacy scholars question whether enhanced surveillance in the name of fighting disease can be dialed back once the danger has passed. "I'm not sure that we should be making longer-term judgments, in an emergency situation, about what the right balance is right now," said Jennifer Daskal, faculty director of the Tech, Law, and Security program at American University and a former national security official in the Department of Justice. "That often doesn't work out so well." Pointing back to 9/11, when Congress granted immense surveillance powers to the federal government, Daskal said decisions made during emergency situations tend to lead to overreach...

The rapid spread of the disease has prompted even some traditional defenders of personal privacy to acknowledge the potential benefits of digital tracking. "Public policy must reflect a balance between collective good and civil liberties in order to protect the health and safety of our society from communicable disease outbreaks," the Electronic Frontier Foundation wrote in a blog post earlier this month. But, the group continued, any data collection "must be scientifically justified and ⦠proportionate to the need."

An anonymous reader writes: 57-year-old U.S. Senator Rand Paul has tested positive for the coronavirus, reports CNN, citing a tweet from the senator's Twitter account.

"He is feeling fine and is in quarantine," the tweet reports. "He is asymptomatic and was tested out of an abundance of caution due to his extensive travel and events. He was not aware of any direct contact with any infected person." Another tweet adds that "Ten days ago, our D.C. office began operating remotely, hence virtually no staff has had contact with Senator Rand Paul."

Paul plans to continue working while in quarantine, and hopes to return to the Senate after his quarantine period ends.

The Wall Street Journal reports that as the coronavirus pandemic began, America's Centers for Disease Control and Prevention "provided restrictive guidance on who should be tested."

They're basing that on archived pages on the CDC's own web site. "While agencies in other countries were advising and conducting widespread testing, the CDC, charged with setting the U.S. standard for who should be tested for the virus, kept its criteria limited." Once the CDC deferred testing evaluations to individual physicians and rolled out testing widely, early data show a surge in positive cases, so public-health officials expect a clearer picture of the epidemic's scale to emerge... Containing a virus requires identifying and isolating those who are infected, infectious-disease and public-health experts say. "If we would have had a true understanding of the extent of the disease several weeks ago, implementation of social-distancing measures could have prevented the escalation of the disease," said Neil Fishman, chief medical officer at the Hospital of the University of Pennsylvania and an infectious-disease specialist...

Initially, the CDC recommended only investigating those who had symptoms and had recently traveled to Wuhan, China, or made contact with someone who may have the virus. As the outbreak worsened, it expanded the criteria for travel history slowly, but maintained its recommendation that symptoms be present, despite some cases having mild or no symptoms.

Now, the CDC has turned over authority to physicians to determine who gets tested, but the testing rates vary widely by state.
America's response was also hampered by "a botched initial test batch," according to the article, which meant there were fewer tests available until the agency allowed private laboratories to develop tests.
