Why the World Health Organization took two years to say Covid is airborne

Why the World Health Organization took two years to say Covid is airborne

Nature reports: As 2021 drew to a close, the highly contagious Omicron variant of the pandemic virus was racing around the globe, forcing governments to take drastic actions once again. The Netherlands ordered most businesses to close on 19 December, Ireland set curfews and many countries imposed travel bans in the hope of taming the tsunami of COVID-19 cases filling hospitals. Amid the wave of desperate news around the year-end holidays, one group of researchers hailed a development that had…

How we got herd immunity wrong

How we got herd immunity wrong

David Robertson writes: Herd immunity was always our greatest asset for protecting vulnerable people, but public health failed to use it wisely. In March 2020, not long after Covid-19 was declared a global public health emergency, prominent experts predicted that the pandemic would eventually end via herd immunity. Infectious disease epidemiologist Michael Osterholm, who advised President Biden, opined in the Washington Post that even without a vaccine, SARS-CoV-2, the virus that causes Covid-19, would eventually “burn itself out as the…

Why Russia’s invasion of Ukraine threatens global food supplies

Why Russia’s invasion of Ukraine threatens global food supplies

Tim Lang and Martin McKee write: Reliable access to adequate nutrition is essential for physical and mental health. Vladimir Putin’s illegal reinvasion of Ukraine reminds us that we take our food supply for granted. The consequences will be felt far beyond Ukraine’s borders. The immediate threat is to those under siege. Unable to escape Russian shelling, they are running out of food and water. This is a clear breach of the Geneva Convention, which proscribes “starvation of civilians as a…

What a single metric tells us about the pandemic

What a single metric tells us about the pandemic

David Wallace-Wells writes: Live long enough in a pandemic and you will see the entire narrative landscape shift, even flip, sometimes more than once. As recently as a month ago, Americans of a certain cast of mind could have still looked to China — and indeed all of East Asia, Southeast Asia, and Oceania — with some plausible pandemic envy. Those early lockdowns in Wuhan were brutal, yes; some of the surveillance testing, contact tracing, and quarantine measures imposed in…

Immunologists Prakash Nagarkatti and Mitzi Nagarkatti of the University of South Carolina explain what makes it different from previous variants, whether there will be another…

‘We’ve learned absolutely nothing’: Tests could again be in short supply if Covid surges

‘We’ve learned absolutely nothing’: Tests could again be in short supply if Covid surges

Politico reports: The United States could yet again find itself with too few Covid-19 tests if Congress fails to authorize new funds and cases surge, warn White House officials, diagnostic manufacturers and public health experts. The Biden administration estimates that the testing market will remain stable until the early summer, but rapidly falling demand for once-popular at-home Covid-19 tests is leading some manufacturers to cut back. “If we get to a point where companies really are turning off lines or…

A doctor’s impassioned critique of Big Pharma

A doctor’s impassioned critique of Big Pharma

By Troy Farah, Undark, March 18, 2022 Compared to other high-income countries, the fitness of Americans is in dismal shape — and has been declining for decades. Even before the Covid-19 pandemic accelerated health disparities, crisis on top of crisis has compounded to create even more devastating conditions for a growing number of people, especially marginalized groups. There is the diabetes crisis, the obesity crisis, and, of course, the despair crisis, which includes the rising tide of suicides, alcohol poisoning,…

Another Covid surge may be coming. Are we ready for it?

Another Covid surge may be coming. Are we ready for it?

The New York Times reports: Scarcely two months after the Omicron variant drove coronavirus case numbers to frightening heights in the United States, scientists and health officials are bracing for another swell in the pandemic and, with it, the first major test of the country’s strategy of living with the virus while limiting its impact. At local, state and federal levels, the nation has been relaxing restrictions and trying to restore a semblance of normalcy. Encouraging Americans to return to…

America is zooming through the pandemic panic-neglect cycle

America is zooming through the pandemic panic-neglect cycle

Ed Yong writes: All epidemics trigger the same dispiriting cycle. First, panic: As new pathogens emerge, governments throw money, resources, and attention at the threat. Then, neglect: Once the danger dwindles, budgets shrink and memories fade. The world ends up where it started, forced to confront each new disease unprepared and therefore primed for panic. This Sisphyean sequence occurred in the United States after HIV, anthrax, SARS, Ebola, and Zika. It occurred in Republican administrations and Democratic ones. It occurs…

New research points to Wuhan market as pandemic origin

New research points to Wuhan market as pandemic origin

The New York Times reports: Scientists released a pair of extensive studies on Saturday that point to a market in Wuhan, China, as the origin of the coronavirus pandemic. Analyzing data from a variety of sources, they concluded that the coronavirus was very likely present in live mammals sold in the Huanan Seafood Wholesale Market in late 2019 and suggested that the virus twice spilled over into people working or shopping there. They said they found no support for an…

Got a Covid booster? You probably won’t need another for a long time

Got a Covid booster? You probably won’t need another for a long time

The New York Times reports: As people across the world grapple with the prospect of living with the coronavirus for the foreseeable future, one question looms large: How soon before they need yet another shot? Not for many months, and perhaps not for years, according to a flurry of new studies. Three doses of a Covid vaccine — or even just two — are enough to protect most people from serious illness and death for a long time, the studies…

Wood burners emit more particle pollution than traffic, UK data shows

Wood burners emit more particle pollution than traffic, UK data shows

The Guardian reports: Wood burning in homes produces more small particle pollution than all road traffic in the UK, according to revised government data. The new data significantly cuts the estimated proportion of small particle pollution that comes from wood burners from 38% to 17%. But wood burning pollution remains a “major contributor” to particle pollution, another government report said. Road transport is responsible for 13% of particle pollution. The data shows tiny particle pollution, called PM2.5, produced by wood…

Pharmaceutical drugs have dangerously polluted the world’s rivers, scientists warn

Pharmaceutical drugs have dangerously polluted the world’s rivers, scientists warn

The Guardian reports: Humanity’s drugs have polluted rivers across the entire world and pose “a global threat to environmental and human health”, according to the most comprehensive study to date. Pharmaceuticals and other biologically active compounds used by humans are known to harm wildlife and antibiotics in the environment drive up the risk of resistance to the drugs, one of the greatest threats to humanity. The scientists measured the concentration of 61 active pharmaceutical ingredients (APIs) at more than 1,000…

Heart-disease risk soars after Covid — even with a mild case

Heart-disease risk soars after Covid — even with a mild case

Nature reports: Even a mild case of COVID-19 can increase a person’s risk of cardiovascular problems for at least a year after diagnosis, a new study1 shows. Researchers found that rates of many conditions, such as heart failure and stroke, were substantially higher in people who had recovered from COVID-19 than in similar people who hadn’t had the disease. What’s more, the risk was elevated even for those who were under 65 years of age and lacked risk factors, such…

Did Omicron come from mice?

Did Omicron come from mice?

Carolyn Kormann writes: Last Thanksgiving, Rilu, an eleven-year-old snow leopard and father of seven, began sneezing and wheezing. Snow leopards are native to the Himalayas, but Rilu was born in a zoo in Oklahoma City, then moved to the Miller Park Zoo, in Illinois, in 2011, to form part of the Species Survival Plan—the zoos’ matchmaking effort to maintain a genetically diverse “insurance” population of endangered animals. A PCR test in early December confirmed that Rilu had Covid-19. He developed…

The time to end pandemic restrictions is now

The time to end pandemic restrictions is now

Yascha Mounk writes: In March 2020, I wrote that America should “cancel everything” in response to the acute threat posed by COVID-19: Mass events should be postponed, companies should send employees home from the office, and schools should move classes online. I remain convinced that this was the right thing to do. Before anyone was vaccinated, and before doctors had even a preliminary understanding of how to treat the disease, these measures were necessary to save lives and avert a…
