Many People Lack Protective Antibodies After COVID-19 Infection

Cut to a couple of days ago, when I came across this article in Nature — the first deep dive attempting to answer the question of just how protective those coronavirus antibodies are. And, at first blush at least, the news isn’t great.

What a controversial face mask study says about science in the Covid-19 era

A high-profile dispute between researchers over the role of face masks in preventing Covid-19 is revealing the tensions in how science is conducted during a global pandemic. It’s also raising questions about the role of prestigious journals in elevating findings that may not hold up.

Cause of Common Autoinflammatory Disease May Have Protected Ancestors From Plague

Researchers have discovered that Mediterranean populations may be more susceptible to an autoinflammatory disease because of evolutionary pressure to survive the bubonic plague. The study, carried out by scientists at the National Human Genome Research Institute (NHGRI), part of the National Institutes of Health, determined that specific genomic variants that cause a disease called familial Mediterranean fever (FMF) may also confer increased resilience to the plague.

Editor’s Note:

The genetic basis for diseases is a major focus of research, but can also be linked with evolution. Here the NIH reports on a study about current patients of familial Mediterranean fever and their ancestors fighting bubonic plague.

TB cases and deaths predicted to spike due to COVID-19

The global COVID-19 pandemic could significantly increase the global burden of tuberculosis (TB) due to disruptions to health services, and delays to diagnosis and treatment, according to new estimates published in the European Respiratory Journal.

Where are the COVID-19 Hotspots? Tracking State Outbreaks

There is growing concern about rising COVID-19 cases and other troubling trends in a subset of states that have reopened, and a few Governors and Mayors have either paused reopening or signaled their intention to do. Understanding in which states the pandemic is moving in the wrong, or right, direction, is critical but complex, as no single metric can tell the full story. For example, an increasing number of cases could be the result of more testing or the result of increasing transmission, or a combination of both.

Seeing is believing: Effectiveness of facemasks

Research from Florida Atlantic University’s College of Engineering and Computer Science, just published in the journal Physics of Fluids , demonstrates through visualization of emulated coughs and sneezes, a method to assess the effectiveness of facemasks in obstructing droplets. The rationale behind the recommendation for using masks or other face coverings is to reduce the risk of cross-infection via the transmission of respiratory droplets from infected to healthy individuals.

The US isn’t in a second wave of coronavirus – the first wave never ended

After sustained declines in the number of COVID-19 cases over recent months, restrictions are starting to ease across the United States. Numbers of new cases are falling or stable at low numbers in some states, but they are surging in many others. Overall, the U.S. is experiencing a sharp increase in the number of new cases a day, and by late June, had surpassed the peak rate of spread in early April.

In the year since I donated, the pandemic has made it more important than ever for other Canadians to do the same. But it’s also made me rethink why people help another – and how I could have helped someone, but didn’t
