It ’ s not all Greek to me

By now, we’ve all heard the phrase “variant of concern” referring to a new form of the coronavirus that causes COVID-19. Technically, these variants have mutations that alter how well the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) virus infects our cells. If the new form of the virus is of concern it is usually because the mutations in the spike protein on the surface of the virus are likely to make it more infectious, faster spreading and/or to worse symptoms or lead to more deaths. The national and international health organisations assess new variants of which there are known to be hundreds of thousands, if not millions, on the basis of whether they show increased transmissibility, increased morbidity, increased mortality, increased risk of “long COVID”, ability to evade detection by diagnostic tests, decreased susceptibility to antiviral drugs, decreased susceptibility to neutralizing antibodies, ability to cause reinfections, ability to infect people who have been vaccinated, increased risk of multisystem inflammatory syndrome and long-haul COVID, increased impact on particular demographic or clinical groups. The new variants were initially referred to by the name of the place where they were first identified, although each was given a technical name too to represent their genetic lineage. However, those scientific names, for example, B.1.1.529, are not particularly media friendly nor memorable to non-experts. As such, in M...
