new H3N2 Flu Subvariant circulating in Europe, Belgian Virologist Warns
Table of Contents
A new subvariant of the H3N2 influenza virus is currently causing illness in the United Kingdom and Spain, according to Belgian virologist Marc Van Ranst, as reported on ‘Het Journaal’ on VRT 1. This comes as the holiday season approaches, raising concerns about potential increased transmission.The H3N2 strain is known to disproportionately affect older adults, often leading to more severe illness and potentially a more impactful flu epidemic.
H3N2: Why is it a Concern?
The H3N2 influenza virus is one of three main flu viruses currently circulating. Van Ranst explained that H3N2 tends to cause more severe illness in older individuals. This is significant as a higher proportion of sick elderly people frequently enough translates to a more serious overall flu epidemic.
According to the Centers for Disease Control and Prevention (CDC), H3N2 viruses have historically been associated with more severe seasons and higher hospitalization rates, particularly among older adults and young children. This is due to the virus’s ability to evolve rapidly,potentially reducing the effectiveness of existing antibodies from previous flu seasons or vaccinations.
Holiday Gatherings and Flu Transmission
with the holidays approaching, questions arise about the safety of customary greetings like kissing and hugging. Van Ranst advises that individuals who are not sick can continue these practices. However,anyone experiencing flu-like symptoms or other communicable conditions should refrain from social gatherings to prevent further spread.
The World Health Organization (WHO) emphasizes the importance of practicing respiratory hygiene, including covering coughs and sneezes, and frequent handwashing to minimize transmission during the flu season.
flu Statistics in Belgium
Data from Sciensano, the Belgian institute for health, indicates that approximately 500,000 people in belgium are affected by flu syndrome annually, representing 2 to 8% of the population.
* moderate Flu Epidemic: Affects around 5% of the population.
* Strong Flu Epidemic: Affects around 10% of the population.
Complications requiring hospitalization occur in approximately 1 in 1,000 flu cases. The most severe outcomes, including death, are overwhelmingly concentrated among individuals aged 65 and older, with over 90% of flu-related deaths occurring in this age group, according to Sciensano. The European Centre for Disease Prevention and Control (ECDC) also highlights the increased vulnerability of older adults and individuals with underlying health conditions to severe flu outcomes.
Key Takeaways:
* A new H3N2 flu subvariant is circulating in Europe.
* H3N2 often causes more severe illness in older adults.
* Avoid social gatherings if you are experiencing flu-like symptoms.
* Approximately 2-8% of the Belgian population is affected by flu syndrome annually.
* Individuals over 65 are at the highest risk of severe complications and death from the flu.
Staying Protected This Flu Season
Vaccination remains the most effective way to protect against the flu. The WHO and national health authorities recommend annual flu vaccination, especially for vulnerable populations like the elderly, young children, pregnant women, and individuals with chronic health conditions. In addition to vaccination, practicing good hygiene and staying home when sick are crucial steps in preventing the spread of influenza.
