The world is unprepared for the next pandemic, report says

The New York Times reports: Nearly two years into the Covid-19 pandemic, the world remains “dangerously unprepared” for the next major outbreak, according to a new report. The 2021 Global Health Security Index, released on Wednesday, ranks 195 countries according to their capacity to respond to epidemics and pandemics. The inaugural version of the index, published just months before the first Covid-19 cases were detected, concluded that no nation was ready for such a crisis. Overall, the world is not…

What’s next for Covid’s viral evolution

What’s next for Covid’s viral evolution

Nature reports: As the world sped towards a pandemic in early 2020, evolutionary biologist Jesse Bloom gazed into the future of SARS-CoV-2. Like many virus specialists at the time, he predicted that the new pathogen would not be eradicated. Rather, it would become endemic — the fifth coronavirus to permanently establish itself in humans, alongside four ‘seasonal’ coronaviruses that cause relatively mild colds and have been circulating in humans for decades or more. Bloom, who is based at the Fred…

Omicron is fast moving, but perhaps less severe, early reports suggest

Omicron is fast moving, but perhaps less severe, early reports suggest

The New York Times reports: The Covid-19 virus is spreading faster than ever in South Africa, the country’s president said Monday, an indication of how the new Omicron variant is driving the pandemic, but there are early indications that Omicron may cause less serious illness than other forms of the virus. Researchers at a major hospital complex in Pretoria reported that their patients with the coronavirus are much less sick than those they have treated before, and that other hospitals…

Pro-Trump counties now have far higher COVID death rates. Misinformation is to blame

Pro-Trump counties now have far higher COVID death rates. Misinformation is to blame

NPR reports: Since May 2021, people living in counties that voted heavily for Donald Trump during the last presidential election have been nearly three times as likely to die from COVID-19 as those who live in areas that went for now-President Biden. That’s according to a new analysis by NPR that examines how political polarization and misinformation are driving a significant share of the deaths in the pandemic. NPR looked at deaths per 100,000 people in roughly 3,000 counties across…

WHO says no deaths reported from Omicron yet as Covid variant spreads

WHO says no deaths reported from Omicron yet as Covid variant spreads

The Guardian reports: The Omicron variant has been detected in at least 38 countries but no deaths have yet been reported, the World Health Organization has said, amid warnings that it could damage the global economic recovery. The United States and Australia became the latest countries to confirm locally transmitted cases of the variant, as Omicron infections pushed South Africa’s total cases past 3 million. The WHO has warned it could take weeks to determine how infectious the variant is,…

Where did ‘weird’ Omicron come from?

Where did ‘weird’ Omicron come from?

Science reports: Since South African scientists announced last week they had identified an unsettling new variant of SARS-CoV-2, the world has anxiously awaited clues about how it might change the trajectory of the pandemic. But as big a mystery—if less urgent—is where and how Omicron evolved, and what lessons its emergence holds for avoiding future dangerous variants. Omicron clearly did not develop out of one of the earlier variants of concern, such as Alpha or Delta. Instead, it appears to…

A virus’s genes hold a record of where it’s traveled, and when. imaginima/E+ via Getty Images By Claire Guinat, Swiss Federal Institute of Technology Zurich; Etthel Windels, Swiss Federal Institute of Technology Zurich, and Sarah Nadeau, Swiss Federal Institute of Technology Zurich More than 250 million people worldwide have tested positive for SARS-CoV-2, usually after a diagnostic nose swab. Those swabs aren’t trash once they’ve delivered their positive result, though. For scientists like us they carry additional valuable information about…

Omicron risks infecting vaccinated people but may not cause them severe illness

Omicron risks infecting vaccinated people but may not cause them severe illness

The Wall Street Journal reports: The Omicron variant of the Covid-19 virus could lead to more infections among vaccinated people, according to several scientists, but some said there were reasons to believe the shots would protect against severe disease. While the new variant might evade the antibodies generated in reaction to the vaccines, the virus will likely remain vulnerable to immune cells that destroy it once it enters the body, said Ugur Sahin, co-founder of BioNTech SE, which sells a…

It looks like Omicron causes milder illness – is this how COVID becomes endemic?

It looks like Omicron causes milder illness – is this how COVID becomes endemic?

AP Photo/Denis Farrell By Hamish McCallum, Griffith University These are very early days in terms of our understanding the Omicron variant. What is known is that it has a large number of mutations, particularly in the spike protein and it appears to be rapidly spreading in specific parts of the world. Very early indications from Africa suggest it does not cause particularly severe disease (though the World Health Organization has urged caution given the limited data available). At this point,…

How the Omicron variant rattled the world in one week

How the Omicron variant rattled the world in one week

The Wall Street Journal reports: Over coffee at his office on Tuesday, Tulio de Oliveira, director of South Africa’s Center for Epidemic Response and Innovation, let a colleague in on a secret. “There’s something going on,” he told Alex Sigal, a virologist growing coronaviruses at a South African laboratory. “They’ve found a variant they’ve never seen before.” For days, case numbers in the nation had been rising rapidly. Puzzled lab technicians had been getting back Covid-19 tests that were positive,…

WHO chief: Omicron backlash against Africa shows why world needs pandemic treaty

WHO chief: Omicron backlash against Africa shows why world needs pandemic treaty

Politico reports: It’s time for a new pandemic treaty, the chief of the World Health Organization said on Monday. The emergence of the new Omicron coronavirus variant amid vaccine inequity and the rapid imposition of travel bans on southern African nations “demonstrates just why the world needs a new accord on pandemics,” said WHO boss Tedros Adhanom Ghebreyesus, at a special session of the World Health Assembly. Countries are gathering at the session where they will agree to start negotiations…

Humans have evolved to stay active even in old age, new hypothesis claims

Humans have evolved to stay active even in old age, new hypothesis claims

Science Alert reports: In the modern western world, people tend to reduce their levels of physical activity as they get older. But with this inactivity comes a raft of adverse health effects, so why didn’t evolution engineer us so that people could maintain a decent quality of life as they inevitably slow down? In a newly published paper, researchers argue it is because we aren’t meant to reduce our physical activity as we age at all. Enter the ‘active grandparent…

How dangerous Omicron is, won’t be known for weeks

Science reports: At 7.30 a.m. on Wednesday, Kristian Andersen, an infectious disease researcher at Scripps Research in San Diego, received a message on Slack: “This variant is completely insane.” Andrew Rambaut of the University of Edinburgh was reacting to a new SARS-CoV-2 genome sequence found in three samples collected in Botswana on 11 November and one picked up a week later in a traveler from South Africa to Hong Kong. Andersen looked at the data and then replied: “Holy shit—that…

Ten million deaths a year

Ten million deaths a year

David Wallace-Wells writes: Not​ all deaths are created equal. In February 2020, the world began to panic about the novel coronavirus, which killed 2714 people that month. This made the news. In the same month, around 800,000 people died from the effects of air pollution. That didn’t. Novelty counts for a lot. At the start of the pandemic, it was considered unseemly to make comparisons like these. But comparing the value of human lives is one thing the machine of…

How Norilsk, Siberia, became one of the most polluted places on Earth

How Norilsk, Siberia, became one of the most polluted places on Earth

Marianne Lavelle reports: It was 2 a.m. and the sun was shining, as it does day and night in mid-July in Norilsk, a Siberian city 200 miles north of the Arctic Circle. Igor Klyushin went to the bank of the river where he used to fish with his father for grayling, a sleek and dorsal-finned beauty known for its graceful leaps above the water surface. “A very merry fish,” Klyushin recalled. “It enjoys cold and clean, clean water.” He doubted…
