Coronavirus disease (COVID-19)

No link between hypertension drugs and COVID-19 risk, study rules

takeing drug

On March 17, 2020, the American College of Cardiology (ACC), the American Heart Association (AHA), and the Heart Failure Society of America (HFSA) issued a joint statement urging researchers to address certain gaps in our understanding of COVID-19 risk.

More specifically, the ACC, AHA, and HFSA pointed out a need to clarify whether or not people who have taken antihypertensive medication — that is, the drugs that help lower blood pressure — are at higher risk of developing COVID-19 or experiencing a severe form of the disease.

A majority of vaccine skeptics plan to refuse a COVID-19 vaccine, a study suggests, and that could be a big problem

Dr. Anthony Fauci

The availability of a vaccine for the novel coronavirus will likely play a key role in determining when Americans can return to life as usual. Dr. Anthony Fauci, head of the National Institute of Allergy and Infectious Diseases, on April 30 announced that a vaccine could even be available by January 2021.

Whether a vaccine can end this pandemic successfully, however, depends on more than its effectiveness at providing immunity against the virus, or how quickly it can be produced in mass quantities. Americans also must choose to receive the vaccine.

New drug candidate against the novel coronavirus

COVID-19 treatment

A team of scientists from China has found a new candidate drug against the novel coronavirus, SARS-CoV-2, which works by inhibiting a key part of the virus’s machinery.

Much of the world is on hold until scientists find a vaccine for the novel coronavirus, which has, so far, claimed hundreds of thousands of lives.

However, with current estimates suggesting that a vaccine is 12–18 months away, many people are placing increasing hope on an effective treatment for COVID-19.

Loss of smell may suggest milder COVID-19, study finds


New research suggests that loss of smell as a symptom of COVID-19 may indicate a mild case of the disease.

A new study has found that loss of smell, which is a reported symptom of COVID-19, may indicate that a person will experience a milder case of the disease.

The research, which features in the International Forum of Allergy & Rhinology, may be valuable in allowing clinicians to identify which COVID-19 patients require hospitalization and which may be able to self-treat the disease at home.

How Apple and Google will let your phone warn you if you’ve been exposed to the coronavirus

Coffee shop

On April 10, Apple and Google announced a coronavirus exposure notification system that will be built into their smartphone operating systems, iOS and Android. The system uses the ubiquitous Bluetooth short-range wireless communication technology.

There are dozens of apps being developed around the world that alert people if they’ve been exposed to a person who has tested positive for COVID-19. Many of them also report the identities of the exposed people to public health authorities, which has raised privacy concerns. Several other exposure notification projects, including PACT, BlueTrace and the Covid Watch project, take a similar privacy-protecting approach to Apple’s and Google’s initiative.

Are blood clots to blame for COVID-19 deaths?


Several research teams writing in the journal Radiology suggest that blood clots play a significant role in why some people become seriously sick with COVID-19.

The death toll from COVID-19 continues to rise daily. But how SARS-CoV-2, the new coronavirus that causes the disease, actually causes death remains poorly understood.

Clinical reports show that people with severe COVID-19 develop pneumonia, acute respiratory distress syndrome, and multiple organ failure.

What does survival of the fittest mean in the coronavirus pandemic? Look to the immune system

Charles Darwin

Charles Darwin popularized the concept of survival of the fittest as a mechanism underlying the natural selection that drives the evolution of life. Organisms with genes better suited to the environment are selected for survival and pass them to the next generation.

Thus, when a new infection that the world has never seen before erupts, the process of natural selection starts all over again.

In the context of the coronavirus pandemic, who is the "fittest"?

Severe COVID-19: Study investigates a possible underlying mechanism


New research has found a link between increased COVID-19 severity and higher blood levels of neutrophil extracellular traps (NETs). NETs usually help defeat infections, but in some COVID-19 cases, they may have something to do with disease severity.

In a new study, researchers from the University of Michigan in Ann Arbor, Northwell Health in New York City, and Cold Spring Harbor Laboratory, also in New York, NY, have made a discovery that could help advance scientists’ knowledge about how COVID-19 progresses.

Vaccine Hesitancy Post-COVID-19: Will Our Memory Fade or Last?

A child receiving a vaccine

Full-scale efforts are underway to develop a vaccine free us from COVID-19’s deadly grip. But even if they succeed (and that’s no guarantee), the question regrettably must be asked: Will people take it?

Given the severity of the current crisis, taking countless lives and sending our socioeconomic systems to the brink of collapse, it seems unimaginable that anyone would reject a Coronavirus vaccine. Yet, over the last 2 decades, vaccine hesitancy has risen so substantially that the WHO now considers it a major threat to global health.

Why are necropsies not performed in the Covid-19 pandemic?

Prof. Dr. V. Astarastoae

The COVID-19 medical crisis we are going through has brought us into situations we have never encountered before, from the phenomenon of social distancing to the lack of any articulated solution plan. Prof. Dr. Vasile Astarastoae made several analyzes in the last weeks of the medical oddities from COVID-19 crisis. Today it raises a new question: why are necropsies not performed on the bodies of those who died because of SARS-CoV-2 virus. This is all the more strange as it is the first time that this medical research tool is not used.

The COVID-19 crisis is certainly a phenomenon that humanity has never encountered. Isolating people in homes, but also the lack of a solution plan, other than driving with masks on their faces and the possibility of being stuck at any time, make this medical problem even more complicated.
