Winter and fall have not been kind to us in recent years, but a sneaky omicron mutation could lead to an outbreak of COVID-19 this fall.
In 2020, COVID-19 instances started to increase in October. And last year, we were, in a sense, in the quiet before the storm as the omicron variety started on its path to global dominance at the end of November, while the delta-driven case counts were steadily declining. What will happen as omicron continues to develop and many people stop using masks in our third pandemic winter?
Time will only tell. But there are already some indicators that we might be in for yet another wave of illnesses, hospitalizations, and fatalities. One is that some European nations, like the United Kingdom, are seeing an increase in cases and hospitalizations.
Typically, what occurs abroad foretells what will take place in the US. Cases are still declining both nationally and in most states. As temperatures drop and more people assemble indoors, where the coronavirus is more prone to spread, researchers are concerned that this may not be the case for very long. For instance, coronavirus levels in wastewater have sharply increased in some Northeastern states, indicating an increase in transmission even if it hasn't yet been captured in official case counts.
This year's wild card further complicates things. Numerous omicron variants exist. How might they alter the impending course of the pandemic?
Answering that question is difficult. On the one hand, with additional medicines available and an omicron-specific booster, we're in a significantly different position than we were two years ago or even last year. But the coronavirus has a history of throwing us some unexpected curveballs. Winter is predicted to bring yet another wave, although it's unclear what it will look like or how high it will peak.

The majority of people have been exposed to the virus, whether by immunization, an infection, or both of those less favorable routes. That implies that the virus's mug photo is present in our immune systems. As soon as the coronavirus enters our noses, throats, or lungs, our antibodies and T cells are programmed to go into high gear.
The bad news is that the omicron variety has acquired a few disguises over the past year in the form of mutations that assist the virus in evading our immune systems. Over the course of the summer, a version known as BA.5 overtook its relatives BA.2 and BA.2.12.1 to take over. Researchers are currently monitoring a new alphanumeric form of the omicron family.
As happened in 2021 with the delta and omicron variants, it is feasible for a brand-new unsettling variant to sporadically emerge and outcompete all of its relatives. "pi" would be the next name on the list.
Another, maybe more plausible, scenario is that during the coming months, a swarm of novel varieties will capture our attention rather than a single lineage that spreads over the globe. That's in part due to the competition between the virus and our immune systems.
