Published on 1 March 2021 in the SA Medical Journal, the article titled Viruses, variants and vaccines was co-authored by Rhodes University’s Professor Rosemary Dorrington from the Department of Biochemistry and Microbiology. The article addresses some of the major global clinical, sociological and economic issues brought about by the SARS-CoV-2 pandemic, focusing on short-term factors such as virus variants and vaccine efficacy, and also considers the longer-term implications of the current pandemic.
According to the article, SARS-CoV-2 will probably remain in circulation for decades or longer. However, “The core issue is not whether SARS-CoV-2 is here to stay, like its common cold-causing relatives, but how we as the human race will deal with it in the medium to long term. How will human behaviour and lifestyles ‘normalise’ in a ‘post-COVID pandemic’ world?”.

Ask a woman for the most embarrassing, frustrating, and uncomfortable health condition she’s ever dealt with down there, and bacterial vaginosis (BV) likely tops the list. While many women may have BV without any symptoms, the
telltale signs of a life-disrupting infection include surprise plops of gray, green, or white vaginal discharge, a fishy odor, itchy skin, a burning sensation when you pee, and painful sex all of which can make even the most empowered woman feel anxious and insecure.
Despite the shame and stigma that sometimes comes with BV, what’s happening isn’t your fault. Rather, it’s a reflection of the complex and ever-changing balance of bacteria inside the vagina.

Ancient alchemists dreamed of transforming base materials like lead into gold and other valuable commodities. While such efforts generally came to naught, researchers today are having some success in extracting a variety of useful products like aviation fuels, lubricants, solvents, food additives and plastics from organic waste.
The trick is accomplished with the aid of specialized bacteria, whose metabolic activities can convert simpler chemicals into useful products through a microbial growth process knows as chain elongation.
