The debate over when to lift mask mandates continues. The CDC extended mask guidance on airplanes, among other forms of mass transit, for an additional two weeks. The war over masks in elementary school continues to be waged. A new model attempts to provide more data on the interaction of the three horsemen of non-pharmaceutical intervention, face masks, room ventilation, and distance in short and long-range airborne transmission.
Reconsidering zoos, the most famous of monkeys, the symbolism of masks and a goldfish drives their aquarium.
As Omicron continues to infect its way across America, let us not forget its viral companion: influenza. How is that working out?
Instagram recently censored the Cochrane Collaboration, a highly respected nonprofit group made up of medical experts, for allegedly sharing "false content" about COVID-19. This is an inevitable consequence of the growing push for social media censorship.
What went wrong during the COVID-19 pandemic? A team of public health researchers recently outlined some of the crucial policy mistakes we made and explained how we might avoid them in the future.
Over the last year, the number of immune individuals necessary to achieve herd immunity has risen from 70% to 90%. Is it even possible to achieve herd immunity? Every other disease has herd immunity; why not COVID-19? And another problem, why is COVID-19 different from its siblings SARS or MERS?
The media likes to compare COVID-19 outcomes in different states based on carefully selected metrics. A closer look indicates that these match-ups are less compelling than reporters think. This has consequences for the public's trust in science.
Scientific American says there's good evidence to support mandatory masking in schools. A careful look at the data suggest the situation is more complicated.
Given the abundance of readily available, free, effective (albeit imperfect) vaccines for many months, why are we seeing a surge in COVID cases and hospitalizations? Let's examine the three primary factors that dictate the severity of an outbreak of a viral illness.
A new clinical trial examining the efficacy of masking on COVID-19 transmission has garnered a lot of media coverage. What the study shows and what people have been told the study shows are very different.
 It has been sixty years since the Concert for Bangladesh; It is doubtful that this low-income country, with half the population and 1/66th the size of the US, has had as much coverage in the media as now, with a report on the efficacy of masks in fighting COVID-19. It is a well-thought-out, performed, and reported study and deserves better than the superficial reporting of the media and 280 character Tweets. Let me provide a deeper look.
As a result of the latest Presidential election, state legislatures are garnering a great deal of publicity about a host of new laws surrounding voter registration.
