Influenza activity at high levels


People in high-risk groups are urged to get vaccinated against influenza, as the number of reported cases of influenza-like illness (ILI) in Ireland has increased again in the past week.

Influenza is actively circulating in community and hospital settings in Ireland. ILI rates have risen to 95.3 per 100,000 population during the week ended January 8th 2017 and are above baseline threshold levels. Influenza hospitalisations and outbreaks in residential care facilities are at high levels and are continuing to increase. Influenza A (H3) is currently the main influenza virus circulating in Ireland, mainly affecting those aged 65 years and older. Influenza is expected to increase over the coming weeks and to continue circulating in the community up to mid February.

The influenza vaccine is available free of charge from GPs for all people in at risk groups, and from pharmacists for everyone in risk groups aged 18 years and over. An administration charge may apply to people who don’t hold medical cards or GP visit cards.

At-risk groups for the vaccine are:

  • All those aged 65 years and older
  • People including children with chronic illness requiring regular medical follow-up such as chronic lung disease, chronic heart disease, chronic neurological disorders, neurodevelopmental disorders and diabetes
  • Those with lower immunity due to disease or treatment
  • All pregnant women. The vaccine can be given at any stage of pregnancy.
  • Those with morbid obesity i.e. Body Mass Index ≥ 40
  • Residents of nursing homes, old people's homes and other long stay facilities
  • Health care workers and carers of those in at-risk groups.

Vaccination remains the most effective means of preventing infection by seasonal influenza viruses and can reduce severe disease that can lead to hospitalisation and death.

Anyone who gets flu should stay at home, rest, drink plenty of fluids and use over-the-counter remedies like paracetamol to ease symptoms. Advice, tips, information and videos on getting over flu and other common illnesses are available at a new HSE website,

Anyone in one of the high-risk categories should contact their GP if they develop influenza symptoms. GPs may wish to prescribe antivirals for those presenting with influenza in the high risk groups.

Covering your nose and mouth with a tissue when you cough and sneeze (catch it), disposing of the tissue as soon as possible (bin it) and cleaning your hands as soon as you can (kill it) are important measures in helping prevent the spread of germs and reducing the risk of transmission. Posters on respiratory etiquette are available on the HPSC website.

ILI GP consultation rates give an indication of the overall community levels of influenza activity in Ireland and are reported by a network of sentinel GPs as part of a surveillance system jointly run by the Irish College of General Practitioners, the National Virus Reference Laboratory and the Health Protection Surveillance Centre.

The weekly influenza surveillance reports and further information on influenza and flu vaccine are available on the HPSC website.
