Corona virus: signs of subvariant JN.1

As of December 2023, the JN.1 variant has spread rapidly and is now the dominant strain of the virus in the United States, according to the Centers for Disease Control and Prevention (CDC). The strain has led to a decline in the total number of new cases and hospitalizations in the United States. JN.1 is also becoming dominant in the UK, France, China, India and other European countries, including Greece, according to the CDC.

EKPA’s Department of Epidemiology and Preventive Medicine Professors Theodora Psaltopoulos, Biologist Panayota Zacharakis and Dr. Yanis Danasis summarize the latest data. International health authorities note that it is not yet clear whether the JN.1 variant causes any special symptoms compared to other variants. However, the CDC notes that the nature and severity of symptoms depends largely on the individual’s immunity and overall health at the time of infection with this variant.

It is important to note that the scientific community continues to closely study the JN.1 variant and its impact on the epidemiological picture. Scientists emphasize the need to monitor possible changes in the nature of symptoms and the effectiveness of immune responses in response to this strain.

In addition, extensive studies are being conducted to evaluate the efficacy of existing vaccines against the JN.1 variant. This is an important aspect in controlling the spread of the virus, and the results of these studies may influence vaccination strategies and additional control measures.

We will monitor developments and provide updates as new information becomes available.
