To date, none of the available vaccines prevent transmission from one individual to another. Most focus on decreasing the severity of symptoms. In the short term, that is a very effective strategy. In the longer term it can turn into a double-edged sword.  Evolving new strains of COVID may be more beneficial than detrimental. Consider […]

With the advent of antibiotics in the first half of the last century, traditional public health went into hibernation.  Communicable or infectious diseases surfaced only occasionally, and usually only in small outbreaks of old foes such as TB, leprosy and polio. Most of these outbreaks were contained and in relatively inaccessible locations subject to a small […]

Since March 2020, most places in the world have been through several versions of CoVID-19 lockdown. The most extreme level, currently in force in several cities in the USA, prohibits social contact beyond the immediate household throughout the rest of the year. Those who can work from home are expected to do so. Those who […]

Absolute risk is the likelihood an event will occur. Relative risk is the likelihood an event will occur in one group compared to another. In CoVID-19 terms, the absolute risk of dying from the disease is low. However, if we look at very old residents of care facilities who have multiple health problems compared with […]

Over the past two decades, three human coronaviruses (SARS-CoV, MERS-CoV, and SARS-CoV-2) have emerged worldwide and there is still no approved vaccine for any of them. Greedy nations race each other in a drug-ridden CoVID Olympics, spending billions to find the gold medal vaccine. Yet we are told the greatest elite performer on earth – […]

CoVID is no longer just a health concern. As clinicians we now understand the disease a little better, are comforted that most cases are mild and self-limiting, and relieved that the intensive care resources are becoming equipped to manage the increase in patient numbers. Even the danger to health care workers of too much exposure […]

CoVID-19 is all about lungs and breathing. As the infection increases in seriousness so the need for breathing assistance becomes greater. Critical and intensive care units (ICUs) provide the optimal support for these life-threatening breathing problems. But are they ready for the expected surge in cases? There will never be enough ICU beds. Overall, critical […]

Global travel no doubt contributes to polluting our planet, but is it really responsible for the spontaneous outbreaks of CoVID-19 (coronavirus) occurring around the world? The recent outbreak in Italy, which has not been linked to any human carrier, makes me wonder. It is time to look into transmission beyond human-to-human. Granted we humans are […]

Doctors, nurses, and other health care professionals have a long history of wearing face masks in clinical environments, but I’ve never seen a person in scrubs walking down the street in a face mask.  That look is generally reserved to  tourists, particularly from Japan and China, who wear masks as they see the sights. Surgical […]

The Olympics are never without a health issue. In the pastit has been doping. But doping is never going to be eradicated, despite the number of exposes of athletes, withdrawn medals and public outrage. Now there is a new target – the Zika virus. The Olympics are a global health risk, rather than a celebration […]
