The Rise of COVID and New Variants: A Christmas Concern ( JN.1 COVID ) (2024 )

The Rise of COVID and New Variants: A Christmas Concern

As Christmas approaches, the rise in COVID numbers is causing concern among health professionals. Dr. Peter Chin-Hong from UCSF and Dr. Dean Winslow from Stanford are both emphasizing the increase in respiratory viruses, including the new JN.1 COVID variant. Despite the variant being highly transmissible, it does not appear to cause more severe disease than earlier variants.

With millions of people traveling for the holiday, the risk of COVID spread is high, especially in crowded areas like airports and planes. While the air on modern aircraft is relatively low-risk due to high turnover rates and HEPA filtration, walking through terminals, TSA lines, and crowded jetways poses a higher risk.

Both doctors advise wearing masks and increasing airflow by opening the gasper fans on commercial airliners. These precautions can help reduce the risk of contracting COVID and other respiratory viruses during holiday travel. As the new variant spreads across the country, it is crucial for individuals to take necessary precautions to stay healthy and safe. 

The CDC Warns of Rapid Spread of Coronavirus Subvariant JN.1 in the US

The Centers for Disease Control and Prevention (CDC) has issued a warning about the rapid spread of the coronavirus subvariant JN.1 in the United States. This subvariant is now responsible for approximately 20% of new COVID-19 infections in the country and has become dominant in the Northeast, where it is estimated to be the cause of about a third of new cases.

According to variant trackers, JN.1 is expected to become the leading coronavirus variant worldwide within a matter of weeks. The World Health Organization has named it a variant of interest due to its rapidly increasing spread, although the additional public health risk remains low.

Health experts believe that the heavily mutated JN.1 is also benefitting from holiday travel and waning immunity from previous COVID-19 vaccinations. In addition to getting vaccinated, Dr. Kurt Williamson, an associate professor in the biology department at the College of William & Mary, recommends simple preventive measures such as hand-washing, wearing masks around high-risk individuals, and staying home if feeling unwell.

It is important for the public to remain vigilant and take necessary precautions to prevent the further spread of this fast-growing subvariant.
