The US Centers for Disease Control and Prevention (CDC) estimates that 99.5% of all cases in the United States are now omicron.
Omicron is far less deadly than its predecessors, but its hyper-transmissibility leads to an increase of people getting infected with the disease, resulting in more hospitalizations and deaths. It has quickly evolved to near-total dominance.
How likely is the possibility of super variants such as deltacron?
When omicron strikes communities already plagued by the delta variant, the medical community feared the possibility of recombination.
Deborah H Fuller, a professor of microbiology at the University of Washington School of Medicine who studies coronavirus and vaccinations, explains that recombination events are rare, but theoretically possible.
Fuller tells Quartz that a recombination event is when two viruses infect the same cell, which is rare.
The likelihood of a recombination event is that omicron and delta have been found in different parts of the lung, making it even more difficult for a omicron to occur.
A recombination event to produce such a virus requires both viruses to enter into the same cell, said Fuller.
Has omicron eased the outbreak to an end?
omicron is four times more transmissible than the delta variant, according to some experts.
Omicron is going to be dominant in the foreseeable future, but the only caveat is that there is a more transmissible variant with increased immune evasion properties to outweigh our natural defenses either from the vaccination or the previous infection, but that is still a highly unlikely situation, said Sumit Chanda, an infectious disease researcher at the Scripps Research Department of Immunology and Microbiology.
Given the number of unvaccinated populations having hospitalizations and deaths, Chanda believes in the long run that one or two new variants of coronavirus might exist from now on, leading us to an outbreak.
Chanda believes that we are retaliating for the virus genetically, balancing its ability to enter cells, evade the immune response, and become transmissible.
With the exception of measles, the world hasn't seen a virus with such levels of transmission: "It will be very difficult for the virus to continue to evolve to a point at which it has a clear advantage."
