US COVID-19 pandemic: Cases vs deaths paradox
The US CDC data reveals an interesting age-specific case versus deaths paradox. Look at the following graph. I created the graph using data available at the US CDC website. Of all the COVID-19 cases, 85.6 percent occurred among those aged equal and below 64 years. In contrast, of all the COVID-19 deaths, 80.6 percent occurred among those aged 65 and above. Now, my message is clear and straightforward based on this graph: Minimize the contact between these two age groups. How can we minimize the contacts between these two age groups? My suggestions are; Provide financial and other incentives to…

Face mask compliance: A simple study design
This face mask compliance observational study attracted my attention because of its simplistic nature and reader-friendly presentation. I must thank Assistant Professor Susan Parham and Dr Matthew Hardy for publishing the study on The Centre for Evidence-Based Medicine website. About the location Researchers have chosen a small tourist city in Paris for this face mask compliance study. Their reason for choosing this place is because of its popularity among both tourists and the local population. Wearing face coverings became mandatory in this place by the time they conducted the observation. Location selection Professor Susan Parham and Dr Matthew Hardy have…

“They told me it’s out there: The Pacific Vortex.

Spin in reporting a case-control study
This post follows up on my previous post on the same topic of cannabis use and psychosis. I was inspired by a podcast presented by Matt, Chris, and Don from the Population Health Exchange of the Boston University School Health Public Health. My focus here is on the “spinning in science writing”. About the study This was a multi-centre case-control study, which involved several countries. It appeared in The Lancet Psychiatry in 2019 under the title, “the contribution of cannabis use to variation in the incidence of psychotic disorders across Europe (EU-GEI): “A multicenter case-control study”: You can access the…
Avoid traps in risk communication
As an individual who closely follows pandemic communication, I have been observing some communication “traps” that the communicators fall into. During my research on this, I found excellent advice from the US CDC website with regard to this topic. I am sharing relevant pieces from that post here. This post details out dos and don’ts when we communicate events related to an outbreak. Dos Do not s define technical terms in plain language Use language that even a small section cannot understand Ask whether you have made the information clear. Do not assume that everything is clear. use examples or…
