Covid origins
ANGELA Rasmussen studies the interactions between hosts and pathogens and how they shape disease. Before the pandemic, she worked on the emerging viruses that cause Middle East respiratory syndrome (Mers), Ebola, dengue and avian flu. Then, when Covid-19 erupted, the American virologist, who works at the University of Saskatchewan in Canada, was drawn into the…

The global race to contain Omicron
WHAT does Omicron conjure in your mind? I’ve seen the new “scariant” compared to Frankenstein’s monster and a Transformer, but I picture it as an overgrown mafioso named “Tiny”, whose trousers stop short of his feet, who uncomplainingly takes on all the dirty work and whose mother loves him.

On the under-explored promise of the immune response in your nose
WHILE everyone celebrated this month’s news that not one but two experimental vaccines against Covid-19 have proved at least 90% effective at preventing disease in late-stage clinical trials, research into understanding how the Sars-CoV-2 virus, which causes Covid-19, interacts with the human immune system never paused… This story first appeared in The Observer on 22 October…

Arms and the virus
LETTING the virus that causes Covid-19 circulate more-or-less freely is dangerous not only because it risks overwhelming hospitals and so endangering lives unnecessarily, but also because it could delay the evolution of the virus to a more benign form and potentially even make it more lethal… This article first appeared in The Guardian on 19 November…

On pathogen evolution
A DEEPLY entrenched idea, that newly emerged agents of disease inevitably evolve to become more benign over time, is scientifically unfounded, according to new research… This story was first published in The Guardian on 19 November 2020. To continue reading, click here.

SARS-CoV-2 is changing at a glacial pace
SCIENTISTS have had eyes on Sars-CoV-2, the virus that causes Covid-19, since the beginning of this pandemic. They can see it is evolving, but it is happening at a glacial pace compared with two other viruses with pandemic potential: those that cause flu and Aids. That is good news for efforts to develop vaccines and treatments,…

Interview: Christian Drosten
CHRISTIAN Drosten, who directs the Institute of Virology at the Charité Hospital in Berlin, was one of those who identified the Sars virus in 2003. As the head of the German public health institute’s reference lab on coronaviruses, he has become the government’s go-to expert on the related virus causing the current pandemic… This article…

Is factory farming to blame for coronavirus?
WHERE did the virus causing the current pandemic come from? How did it get to a food market in Wuhan, China, from where it is thought to have spilled over into humans? The answers to these questions are gradually being pieced together, and the story they tell makes for uncomfortable reading… This article first appeared…
