Last week, the WHO informed that they are monitoring two new sublineages of the Omicron variant — BA.4 and BA.5. “A small number of sequences of BA.4 and BA.5 descendent lineages have now been detected in a few countries. Both have additional mutations in the spike region and unique mutations outside of the spike. The mutations are associated with potential immune escape characteristics,” the organisation said. The announcement has come at a time when infections are rapidly declining globally, with only a very few nations recording a rise in cases. More importantly, the number of deaths due to COVID is at its lowest level since the pandemic started. Worryingly, only 60% of the world’s citizens have got both doses of the vaccine, with Africa lagging behind at just 16%. There is also a drop in the number of tests conducted across the globe
