SARS-CoV-2 fabriqué en laboratoire? Vraiment?

FR La pandémie COVID-19 a apporté avec elle un lot de changements mais aussi une multitude de théories. Parmi ces dernières, nous retrouvons la théorie selon laquelle le virus SARS-CoV-2, responsable de la maladie COVID-19, a été conçu par l’homme en laboratoire. En effet, Luc Montagnier, lauréat d’un prix Nobel, déclarait le 17 avril 2020 à la télévision française qu’« on a ajouté à ce modèle (coronavirus) des séquences du VIH (...)». Depuis, cette théorie a été nourrie par certains, rejetée par d’autres. Tentons d’y voir plus clair. Lire la suite

Standing up for science in the era of COVID-19

At the onset of the COVID-19 pandemic, I had a glimmer of hope that maybe through this crisis, trust in science and the importance of scientific research would become indisputable. It felt like we would finally see an example of what a world without just one vaccine for a deadly infectious disease would look like. But the stories that the world chooses to focus on, and those that are shared across non-expert audiences, tell a different story. Read on

Pandemic danger to the deep: the risk of marine mammals contracting SARS-CoV-2 from wastewater

The current COVID-19 pandemic is caused by the SARS-CoV-2 coronavirus that spreads between humans, primarily through respiratory droplets. However, recent studies demonstrate that SARS-CoV-2 is excreted in feces and can survive in water for up to 25 days, raising the possibility that wastewater provides a separate mode of spread for this coronavirus.

The Racial Disparities of COVID-19

People with compromised immune systems or other health challenges understandably have high rates of mortality from COVID-19. But why does COVID-19 have an unusually large impact among some racialized and ethnic groups? Studies suggest that systemic discrimination against minorities, especially Black communities, is a driving factor that leaves these populations disproportionately affected by COVID-19. Read on

ES Es comprensible que las personas con sistemas inmunes comprometidos u otros problemas de salud tengan altas tasas de mortalidad por causa del COVID-19. Pero ¿cuál es la causa por la que el COVID-19 tiene un impacto tan alto en algunos grupos étnicos? Estudios recientes sugieren que una de las causas es la discriminación sistémica contra las minorías, especialmente las comunidades afroamericanas, provocando que estos grupos sean afectados por el COVID-19 de manera desproporcionada.
