The New Omicron Sublineage: A Cause for Concern?
Once again, the world is braceing itself for a new covid variant. But this time, it's not just any variant - it's a sublineage of Omicron, named HV.1.
After Eris, Pirola, and JN.1, the stage is set for HV.1. The mutation is currently seeing a rapid spread in the United States, pushing its way to the forefront of infections.
In a blink of an eye, HV.1, an Omikron offspring and direct descendant of Eris, has claimed its space in infection charts. Andrea Garcia, Vice President of the American Health Association (AMA), has already sounded the alarm: "We have a new covid variant, and we need to keep an eye on it."
Initially, HV.1 was barely a blip on the radar. By the end of July, it accounted for a minuscule 0.5% of Covid-19 cases in the United States, based on data from the Centers for Disease Control and Prevention. But, by September 30, that figure had surged to a significant 12.5%, and by November, it was a startling 25.2% of cases.
HV.1: The Bronchial Tube Assailant?
The symptoms of HV.1 are akin to those of other Omicron variants. However, because it's a new player in the game, a clear classification remains elusive. Common symptoms include: sore throat, runny nose, cough, fatigue, headache, fever, chills, and muscle aches.
However, researchers claim that HV.1 may attack the bronchial tubes with more fervor than its predecessors. Dr. William Schaffner, Professor of Infectious Diseases at Vanderbilt University Medical Center, tells "Today.com," "It seems to cause a kind of chronic bronchitis, so you can have a cough syndrome that lingers beyond the time you've recovered from other symptoms."
But, while the potential severity is concerning, there's currently no evidence that HV.1 is more contagious than its predecessors. Researchers also indicate that it isn't as extreme as JN.1, which boasts a substantial number of changes to the spike protein, enabling the virus to penetrate cells even more swiftly.
HV.1 Over the Atlantic
As of yet, HV.1 hasn't made an appearance in Germany. The Omicron variants, Eris (51%), Pirola (14%), and the more recent JN.1 (5%), continue to dominate infections here. But, that doesn't mean infections have dwindled.
Since October, there have been over 95,500 covid infections in Germany. The Robert Koch Institute (RKI) reports that more than 22,000 cases were reported by laboratories last week, a spike of 10,000 cases compared to a month prior.
It's worth noting that not everyone with symptoms gets tested. Consequently, the actual number of unreported cases may be higher. And with the odds of HV.1 reaching German shores increasing, we can expect the first cases to surface shortly.
The Battle Against Omicron Sublineages
To curb the spread of Omicron sublineages, researchers are urging widespread Coronavirus vaccinations. They stress the significance of booster shots to fortify immunity against new variants.
Despite the threat posed by HV.1, scientists remain somewhat optimistic about the efficacy of existing vaccines. While further studies are warranted, existing vaccinations are thought to provide some level of protection against HV.1 and its brethren.
Keeping a watchful eye on the evolving coronavirus landscape, the World Health Organization (WHO) is readying countries for potential new vaccine needs. If new variants emerge, capable of bypassing existing vaccines, new vaccines may need to be developed to address the challenge.
