It is a matter of ongoing review that different countries have experienced different levels of infection with SARS-Cov-2. Some had had very low rates to date with a similarly adjusted associated loss of life and others such as the USA, UK and India have had high levels of infection and associated loss of life.
The results of the new study, published (July 21 2020) in JAMA Internal Medicine suggest that, despite the rising numbers, the infection rate suggested to be necessary for herd immunity has yet to be reached. However, the data indicates that many of these people likely had no symptoms or mild illness and may have had no idea that they were infected. The authors indicate that as many as 40% have been without symptoms while the symptoms brought on by the disease can be highly variable.
Existing immune competence, viral load and other elements previously discussed are suggested as reasons for such a high asymptomatic level and the related number needed to be exposed to determine the gradual collapse in new cases is accordingly adjustable. Read the rest of this entry »
Whilst the subject of viral disease is by virtue of the time span since Jan 2020 somewhat overcovered in musings as well as science reviews, each month brings new clarity on the intersecting health and economic risks of a global pandemic.
The SARS-Cov-2 virus is a recognised threat to billions of people around the world, with the risk being compounded for people who live in overcrowded homes, who don’t have access to safe drinking water or nutritious food and are obese. Other risk factors are also relevant but being overweight, according to one of the largest UK studies on the Covid-19 mortality rate to date from Glasgow University, found that as a patient’s Body Mass Index (BMI) increases, so does their risk of having a severe case of the virus. Obesity is a chronic inflammatory disease and it starts with an inflammation in adipose tissue, or body fat. Researchers have proposed there may be a link between this inflammation and an immune system response in Covid-19 patients ultimately manifesting in the terminal induction of the “cytokine storm”.

Few will have missed the photograph of Boris Johnson this week (June 29th, 2020), allegedly performing push ups in No 10. Ostensibly demonstrating his intent to modify his body shape considering his well-publicised experience of the symptomatic response to Sars-Cov-2 infecting many of his cells.
Prior to this, a number of the established newspapers also heavily indicated that there was going to be a top down approach to steer people away from practices that foments weight gain, to weight management and where appropriate loss and a healthier lifestyle. Read the rest of this entry »
