Fauci: US could face ‘fifth wave’ of Covid as Omicron variant nears
Virus variants are cannibalistic. This is well established in influenza cases and appears to be the case in coronavirus cases as well. The DELTA variant has dominated all others in the U.S. for about six months now, replacing the ALPHA variant in two short months, never letting the LAMBDA variant get a foothold and basically eradicating the MU variant here. DELTA is responsible for 99.9% of cases presently in the U.S. There is early evidence from South Africa that the OMICRON variant is dominating the DELTA variant there. If so, it will likely dominate here as well in two to three months.
The severity of illness is the big question so far for OMICRON. Is it more severe, and can it cause "breakthrough" cases for vaccinated people? A report out of Canada appears to be the case. Another early interesting news item out of South Africa is that one doctor reported all the cases she saw were mild. That would be a game changer if true. Think of it: if the OMICRON variant dominates the DELTA variant, basically eradicating it from the U.S. landscape, but causing only mild symptoms and basically hospitalizing just a few people and killing no one, that's a path forward out of the pandemic.
I believe this is a pipe dream, however. I think we are in for a very rough winter. But one never knows. Here's hoping such a pipe dream comes true.
