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 […]

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 […]

Hospitals are full of people sick with CoVID but not all of them are patients. More and more staff in our hospitals are turning up for work that they are unable to do. They are present, but not working at their best, either due to their own health problems, increased CoVID-related workload, or CoVID anxiety. […]

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 […]

In times of overwhelming disaster and limited resources, ingenuity and repurposing can save lives.  For example, the use of stapling wounds on the suture-poor battle fields more than a century ago was game changer. It worked because the purpose of a suture and a staple were similar – to hold two opposing surfaces together. Wrap […]

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 […]
