Our models demonstrate that while social distancing measures clearly do flatten the curve, strategic reduction of contact can strongly increase their efficiency, introducing the possibility of allowing some social contact while keeping risks low. Limiting interaction to a few repeated contacts emerges as the most effective strategy.

COVID-19 is, in many ways, proving to be a disease of uncertainty. According to a new study from Italy, some 43 percent of people with the virus have no symptoms. Among those who do develop symptoms, it is common to feel sick in uncomfortable but familiar ways—congestion, fever, aches, and general malaise. Many people start to feel a little bit better. Then, for many, comes a dramatic tipping point. “Some people really fall off the cliff, and we don’t have good predictors of who it’s going to happen to,” Stephen Thomas, the chair of infectious diseases at Upstate University Hospital, told me. Those people will become short of breath, their heart racing and mind detached from reality. They experience organ failure and spend weeks in the ICU, if they survive at all. Meanwhile, many others simply keep feeling better and… Read More...

In France, the public hospital system in Paris has tallied 490 infected staff members, a small but growing proportion of the system’s 100,000 or so employees. France: By 11 May, when interventions are scheduled to be eased, we project 3.7 million (range: 2.3-6.7) people, 5.7% of the population, will have been infected.

It took only 10 days for signs that the approach here — “elimination” rather than the “containment” goal of the United States and other Western countries — is working.

“Those with antibodies will be able to travel and work, and the rest will be discriminated against.”
Without widespread testing and surveillance, said Angela Rasmussen, a virologist at Columbia University in New York, “we won’t be able to quickly identify and isolate cases in which the patients are presymptomatic or asymptomatic, and thus community transmission could be re-established.” Without a vaccine, the virus is expected to circulate for years, and the death tally will rise over time. [...] Only when tens of thousands of antibody tests are done will we know how many silent carriers there may be in the United States. The C.D.C. has suggested it might be 25 percent of those who test positive. Researchers in Iceland said it might be double that.

Studies are underway to better understand the susceptibility of different animal species to the COVID-19 virus and to assess infection dynamics in susceptible animal species.

Most experts agree that wearing a face mask can stop some virus-laden watery droplets that are thought to be a main coronavirus vector and are expelled into the air when a person coughs, sneezes, just breathes out [Financial Times] or talks [CNN] The importance of viral dose is being overlooked in discussions of the coronavirus. As with any other poison, viruses are usually more dangerous in larger amounts. Small initial exposures tend to lead to mild or asymptomatic infections, while larger doses can be lethal. From a policy perspective, we need to consider that not all exposures to the coronavirus may be the same. Stepping into an office building that once had someone with the coronavirus in it is not as dangerous as sitting next to that infected person for an hourlong train commute. Both small and large amounts of… Read More...

The Seattle area, home of the first known coronavirus case in the United States and the place where the virus claimed 37 of its first 50 victims, is now seeing evidence that strict containment strategies, imposed in the earliest days of the outbreak, are beginning to pay off. While each infected person was spreading the virus to an average of 2.7 other people earlier in March, that number appears to have dropped, with one projection suggesting that it was now down to 1.4. The study found high levels of contamination on commonly used surfaces and in the air of patients' rooms. Samples of air from hallways outside of patient rooms were also positive.

Science will come up with solutions
Coronavirus Info-Database, an attempt to organize the disparate papers, articles and links 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. Covid-19 diagnosis could drop to 10 to 15 euros a person. We need to test as many people as possible. If we know who is infected, who is not and who has recovered, we could greatly relax social isolation requirements and send both the uninfected and the recovered back to work. Although our health-care system is now struggling to produce enough tests even for those who are likely infected, we recommend a massive mobilization that would allow hundreds of millions to be tested. There are two types of tests, and expanding both would be necessary. The polymerase chain reaction, or… Read More...

OH (a former CTO of Autodesk): “I can walk through most buildings and tell you which version of AutoCad was used to design it.” A standard response of both policy makers and private citizens to hardships—from natural disasters to mass shootings—is to offer “thoughts and prayers.” Critics argue that such gestures are meaningless and may obstruct structural reforms intended to mitigate catastrophes. In this study, we elicit the value of receiving thoughts and prayers from strangers following adversity. We find that Christians value thoughts and prayers from religious strangers and priests, while atheists and agnostics are “prayer averse”—willing to pay to avoid receiving prayers. Furthermore, while indifferent to receiving thoughts from other secular people, they… Read More...
