Flu Hospitalisations Surge by One-Third in Just One Week

The number of individuals hospitalised due to flu has surged by one-third over the past week, according to data from the Health Service Executive (HSE). This rise follows a period of decline during the Christmas holidays, highlighting the impact of increased social interactions during the festive season.

As of January 3, 2025, the HSE reported a total of 2,049 flu cases, significantly up from 1,777 cases the previous week. Despite this increase, the figures remain considerably lower than the season’s peak of 3,547 cases. The number of patients in hospital due to flu has also risen, with 512 individuals hospitalised, up from 374 the week prior.

RSV and Other Respiratory Illnesses on the Rise

In addition to flu cases, the HSE recorded 588 cases of respiratory syncytial virus (RSV) last week, which includes 196 hospitalisations. This marks a noticeable increase from the 399 RSV cases and 119 hospitalisations reported for the week ending December 27, 2024. RSV is a common virus known for causing respiratory infections, particularly in young children and the elderly.

Conversely, Covid-19 has remained less prevalent this winter, with only 216 cases and 66 hospitalisations reported in the same timeframe. Additionally, there were 35 cases of norovirus, also referred to as the winter vomiting bug.

The HSE has urged caution concerning these figures, noting that holiday periods can affect data reporting and testing. Dr. Colm Henry, chief clinical officer of the HSE, acknowledged the healthcare system’s response to the recent surge in influenza. On Monday, the HSE confirmed that 700 people were in hospital with flu or RSV.

Dr. Henry stated, “Between the efforts of all services, in hospitals and in the community, we have seen a more efficient flow of patients resulting in less congestion within emergency departments.” He praised the hard work of healthcare staff in mitigating the pressures posed by high levels of respiratory illness alongside other medical needs.

Public Health Advisory and Future Outlook

As the HSE anticipates increased pressure on health services in early January, a period traditionally associated with high demand, Dr. Henry encouraged the public to adhere to public health guidelines. He advised individuals to stay home when feeling unwell, ensure they are up to date with vaccinations, and explore alternative healthcare options such as general practitioners, out-of-hours services, injury units, and pharmacies when necessary.

The HSE continues to stress the importance of vigilance among the public as it navigates the ongoing challenges presented by respiratory illnesses during this season.
