Science explained

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

There have been questions whether humans will develop immunity against SARS-CoV-2, the virus which causes the disease, COVID-19. This question is critical for vaccine developers. Recently, good news came from several immunologists around the world that once our bodies encounter the virus, a protective response to the virus can be achieved. Read on

The physical health impacts of COVID-19 have been well highlighted in the media. However, less discussed are the consequences that the stress of a pandemic in general – and quarantine measures in particular – have on mental health. Research from Australia shines a light on how the current pandemic has affected mental health, specifically the conditions of social isolation and loneliness. Read on

COVID-19 is known as an illness of the respiratory system, but the cardiovascular system has emerged as a critical player in the disease. Pre-existing cardiovascular conditions are linked with higher rates of mortality, and the virus can damage the cardiovascular system, causing potentially long-term injury. Read on

Although COVID-19 is a respiratory illness, a new review of COVID-19 studies published in the journal PLoS One shows that cardiovascular complications are common in COVID-19 patients, which might increase the risk of death. Read on

In January, 2020, during the earliest days of the COVID-19 pandemic, a US-based research scientist was exposed to SARS-CoV-2, the virus responsible for the disease, at a family gathering in Beijing. Within months, samples provided by this anonymous scientist helped to kick-start research in antibody-based treatments for COVID-19 that ultimately lead to an experimental antibody treatment received by US President Donald Trump.

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

These times can be especially alarming for many pregnant and new parents because there does not seem to be enough research, let alone digestible information to communicate what to expect. For this reason, I sought to understand what the data says about COVID-19 exposure and transmission in pregnancy and newborns. Read on

FA این دوران ميتواند براي بسياري از والدين باردار و زائو نگران كننده و استرس زا باشد چرا که به نظر نمي رسد تحقيقات كافي در زمینه [بارداری در دوران كويد-١٩] وجود داشته باشد چه برسد به اطلاعات قابل درکی که بتوان در اختیار قرار داد. به همين دليل من به دنبال درك آنچه داده ها درباره ابتلا به كويد-١٩ در دوران بارداري و انتقال آن به نوزادان مي گويند بودم. ادامه مطلب

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.

"Test, test, test" has been the leitmotif of the World Health Organization (WHO) since the start of the pandemic. However, mass screening requires a rapid, simple and effective detection test. To answer this question, french researchers carried out a real race against the clock in the laboratory in order to produce and market this test in record time. This one, called EasyCOV¹, requires a saliva sample and provides the results in 1 hour. Back on this test and its mode of action. Read on

COVID-19 has thrown North American professional baseball a curveball. An outbreak among players for the Miami Marlins, that has spread to the Philadelphia Phillies and St. Louis Cardinals, brings into question the infection control protocols touted by Major League Baseball. But perhaps more concerning is the report that Boston Red Sox pitcher Eduardo Rodríguez developed myocarditis as a result of COVID-19. Will myocarditis from COVID-19 be a strike out pitch for professional baseball? Read on

It is expected that there will be a second wave of COVID-19 — and possibly more — that could be even more deadly than the current one. We should be better prepared, and modelling and simulation can be useful to predict the evolution of the disease, help reduce the spread of infection and inform public and private policies in terms of prevention. We still have time. Read on

ES Se espera que haya una segunda ola de COVID-19 - y posiblemente más - que podría ser incluso más mortal que la actual.

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.
