The World Health Organization said Wednesday that Omicron subvariants BA.4 and BA.5 have been detected in more than a dozen countries and stimulated fuel sporadic Covid outbreaks across the world, but the heavily mutated strains are still circulating at very low levels.
Omicron, specifically BA.4 and BA.5, is driving the upsurge in South Africa, while BA.2 is dominant worldwide. The relatively high population immunity from vaccination and previous waves is keeping COVID-19 hospitalization and deaths rates at a comparably low level compared to previous waves, it said.
The BA.4 and BA.5 Omicron sub-variants driving up deaths and hospitalizations in places with high immunity is a warning that the global response needs to get ahead of future Variants of Concern. We must invest in research and development to update our tools, rolling out vaccines, tests and treatments to reduce and monitor transmission, while mitigating the impact of the pandemic and protecting essential services. Such actions should underpin an endgame strategy for the pandemic.
