The organisation said the labels do not replace existing scientific names involving numbers, Roman letters and full stops, which convey important scientific information and will continue to be used in research. The simplicity is obvious. While they have their advantages, these scientific names can be difficult to say and recall, and are prone to misreporting, the WHO said in a statement. The next letters on the list, if it comes to it, which it probably will, are epsilon, zeta, eta and theta. The WHO declared that variants of interest and variants of concern will receive a designated Greek letter listed on its website.
