Flu Cases Surge as HSE Warns of Mutant Strain Peak Ahead

The Health Service Executive (HSE) has raised alarms over a significant increase in flu admissions in Ireland, warning that hospitals are currently facing a surge in cases. The HSE has noted that both flu cases and hospitalisations have been “rising rapidly” in recent days. In light of this spike, the public is strongly encouraged to receive their flu vaccinations.

The recent rise in flu cases has been linked to a mutated variant of the H3N2 strain, which is known to cause more severe illness, particularly among elderly individuals. The HSE confirmed that the majority of influenza A(H3N2) samples sequenced by the National Virus Reference Laboratory belong to a new subclade, identified as K. This variant is causing concern as it has not been prevalent in the community for several years, resulting in a lack of built-up immunity among the population.

Vaccination and Public Health Guidance

Despite the emerging strain, the HSE Health Protection Surveillance Centre (HPSC) stated that current flu vaccines continue to provide effective protection. The HSE is urging eligible individuals to obtain their flu vaccinations at participating GP clinics and pharmacies. They warned that flu cases are expected to “continue to rise rapidly over the coming weeks,” with the peak still anticipated.

Statistics reveal that the highest number of flu cases recorded this season has been among individuals aged 65 years and older, as well as those under 15 years. Notably, 73 percent of intensive care unit admissions due to flu this season involved individuals who had not received the current seasonal influenza vaccine.

The HSE is offering free flu vaccines at various healthcare locations, including GP clinics, pharmacies, and community health centres. Individuals at heightened risk of severe flu complications include young children, adults aged 65 and above, expectant mothers, and those with pre-existing health conditions or weakened immune systems.

Recognizing Symptoms and When to Seek Help

The symptoms associated with the H3N2 flu strain largely mirror those of other influenza variants. The HPSC has outlined common flu symptoms, which include fever, fatigue, body aches, and cough. Most cases can be managed at home through adequate rest, hydration, and over-the-counter medications such as paracetamol or ibuprofen.

Pharmacists are available to provide guidance on treatment options and flu remedies. However, patients should seek immediate medical assistance if they experience sudden chest pain, difficulty breathing, or cough up blood.

As the flu season progresses, the HSE continues to emphasize the importance of vaccination and public health measures to mitigate the impact of this virus.
