Microbiomes & misfiring immunity

During the Covid-19 pandemic, many have written about the immune system turning against us. Ali Daneshkhah, a researcher who published a recent article about Vitamin D and COVID stated: “what seems to kill a majority of COVID-19 patients (is) not the destruction of the lungs by the virus itself. It […]

Microbiome and risk factors

Hypertension, obesity, and diabetes have been identified as risk factors for severe COVID-19. Intriguingly, these are diseases that are linked with the microbiome. The microbiota is the collection of microbes that inhabit our bodies. The microbiome is the collection of all of the genes of the microbiota. The vast majority […]


Athena Aktipis interviewed David Quammen, the author of Spillover, for a recent episode on zoonotic epidemic events for her podcast “Zombified.” This was recorded before the pandemic, but is absolutely relevant to our current situation. Did you know, “eight percent of the human genome is DNA that was inserted by […]

Uncertainty, evolution, and drug therapy

The two pharma companies, Sanofi and Regeneron, proposed that a drug called Kevzara might help patients with COVID-19 pneumonia. The rationale was that patients with COVID-19 have an exaggerated immune response, a phenomenon called a cytokine storm, that is responsible for the lung and organ pathology in COVID-19. The logic […]

What does high altitude have to do with COVID-19?

I recently became aware of Cameron Kyle-Sidell, an emergency physician and intensivist in NYC because of his videos describing his experience with COVID-19 patients. Sidell has argued that COVID-19 appears less like traditional ARDS (acute respiratory distress syndrome) and features more in common with high altitude illness. He argues that […]

Virulence evolution in SARS-CoV2

In a recent report, healthcare workers accounted for 11% (1,689 of 15,194) of reported cases. It is clear that being a healthcare worker is a risk factor for symptomatic COVID-19 disease. It is less clear if health care workers get sicker than the general population when infected.  Severe disease in […]

Strokes and COVID 19

The Washington Post today ran a piece entitled Young and middle aged people, barely sick with COVID-19, are dying from strokes. “Doctors sound alarm about patients in their 30s and 40s left debilitated or dead. Some didn’t even know they were infected.” From the article: Sherry H-Y Chou, an intensive […]
