What history tells you about post-pandemic booms – The Economist

People spend more, take more risks—and demand more of politicians. The cholera pandemic of the early 1830s hit France hard. It wiped out nearly 3% of Parisians in a month, and hospitals were overwhelmed by patients whose ailments doctors could not explain. The end of the plague prompted an economic revival, with France following Britain into an industrial revolution. But as anyone who has read “Les Misérables” knows, the pandemic also contributed to another sort of revolution. The city’s poor, hit hardest by the disease, fulminated against the rich, who had fled to their country homes to avoid contagion. France saw political instability for years afterwards.

It’s Time For America’s Fixation On Herd Immunity To End, Scientists Say – NPR

The end of this pandemic sometimes gets boiled down to two words: herd immunity.

FDA Authorizes Longer Time for Refrigerator Storage of Thawed Pfizer-BioNTech COVID-19 Vaccine Prior to Dilution, Making Vaccine More Widely Available – FDA

Making COVID-19 vaccines widely available is key to getting people vaccinated and bringing the pandemic to an end. Pfizer Inc. submitted data to the FDA to support storage of undiluted, thawed vials of its COVID-19 vaccine for up to one month at refrigerator temperatures. This change should make this vaccine more widely available to the American public by facilitating the ability of vaccine providers, such as community doctors’ offices, to receive, store and administer the vaccine.

Clinical Considerations

Researchers are closing in on long covid – The Economist

Britain’s Office for National Statistics (ons) estimates that 14% of people who have tested positive for covid-19 have symptoms which subsequently linger for more than three months (see chart 1). In more than 90% of those cases the original symptoms were not severe enough to warrant admission to hospital. According to the ons, in the four weeks from February 6th nearly half a million people in Britain reported they had had long covid for more than six months—and this will not include any of those infected towards the end of 2020 in the country’s second wave.

Science and Tech

Face masks effectively limit the probability of SARS-CoV-2 transmission – Science

Airborne transmission by droplets and aerosols is important for the spread of viruses. Face masks are a well-established preventive measure, but their effectiveness for mitigating SARS-CoV-2 transmission is still under debate. We show that variations in mask efficacy can be explained by different regimes of virus abundance and related to population-average infection probability and reproduction number. For SARS-CoV-2, the viral load of infectious individuals can vary by orders of magnitude. We find that most environments and contacts are under conditions of low virus abundance (virus-limited) where surgical masks are effective at preventing virus spread. More advanced masks and other protective equipment are required in potentially virus-rich indoor environments including medical centers and hospitals. Masks are particularly effective in combination with other preventive measures like ventilation and distancing.

Computational modelling reveals SARS-CoV-2 mutation ‘hotspots’ – Drug Target Review

A new modelling method could be used as a surveillance tool to monitor emerging infectious SARS-CoV-2 variants, scientists say.

What Happens When Americans Can Finally Exhale – The Atlantic

he pandemic’s mental wounds are still wide open. This time last year, the United States seemed stuck on a COVID-19 plateau. Although 1,300 Americans were dying from the disease every day, states had begun to reopen in a patchwork fashion, and an anxious nation was looking ahead to an uncertain summer. Twelve months later, the situation is very different. Cases are falling quickly. About half as many people are dying every day. Several vaccines were developed faster than experts had dared to predict, and proved to be more effective than they had dared to hope. Despite a shaky start, the vaccination campaign has been successful, and almost half of the country has received at least one shot, including 85 percent of people older than 65. As the pandemic rages on elsewhere in the world, the U.S. is eyeing a summer of reconnection and rejuvenation.
