What is a new variant? Viruses have one aim: to survive and propagate- which they can only do by invading host tissues as they lack the “machinery” to replicate on their own. With this in mind, viruses constantly change to form new “variants.” Some variants emerge and disappear, some persist. Variants which allow a virus to spread more easily or to evade treatment or vaccination are termed “variants of concern.” Background to Omicron On the 24th November 2021 (only 2 weeks ago!) a new variant of then SARSCoV2 virus (B.1.1.529, named Omicron) was reported to the World Health Organization. Only two days later it was declared as a “variant of concern.” Within 2 weeks, the Omicron variant has become the dominant variant circulating throughout most of South Africa. Is Omicron more catchy? We are awaiting more data, but at this stage it seems that Omicron is even more transmissible than…

For those still awaiting or debating the vaccine in your 12-17 year-olds, a couple of pointers: 1️⃣ Why should my child get the COVID-19 vaccine? – The vaccine is highly effective in protecting against severe disease and death. Yes, most children have mild illness, BUT some children get very ill, require hospitalization or ventilation and even die. This is unacceptable in a vaccine-modifiable disease. – The vaccine can help prevent long-term or severe inflammatory conditions such as Long-Covid and Paediatric Multisystem Inflammatory Disease. – Teens can play a major part in transmitting the SARSCoV2 virus: vaccines can reduce transmission and protect the community. – Vaccines can stop other variants from emerging. 2️⃣ Are the vaccines safe? – Medication safety is taken extremely seriously by the regulatory authorities, including the FDA in the USA and SAHPRA in South Africa, who are constantly scrutinizing data. They have approved the use of the…

The basics seem so simple but are often so hard to action! The basics include: – Healthy eating and reducing sugar intake – Exposure to the good outdoors, “sun and sand” – Reducing stress/reducing overfull schedules – Getting enough sleep – Avoiding unnecessary medication. Today we shall only be focusing on healthy eating as it is so important- “we are what we eat!” 1.Healthy eating (food provides the building blocks for a good immunity!) • Eat as much variety as possible • Eat as much “whole food” as possible- processed food is often nutritionally poor and pro-inflammatory • Do not leave out any entire food groups in children- they need them all! A “carb-free” diet, for example, is not appropriate for the vast majority of children. • Veges and fruits are so important for vitamins and anti-oxidants • Zinc and protein are important for tissue repair • Try include some…

A big focus of parenting is on keeping kids healthy. This is, of course, complicated by the fact the children’s immune systems are still developing. Children often encounter various infections ‘for the first time’- which means they have little pre-existing immunity and are prone to getting ill from these infections. In subsequent exposures to similar bugs, an immune memory will have been built up and the illness will tend to be less severe. So what is this thing called the immune system? The immune system is a maze of cells, tissues and organs that work together to: – protect us from invading pathogens – protect us from allergies (over-reacting to “benign” external allergens) – protect us from auto-immunity (attacking our own cells) – resist repeated infections ​ Parts of the immune system are innate (we are born with it) and parts are acquired (built up over time, usually after initial…
