Surveillance of influenza in Northern Ireland

The influenza season started later than normal, clinical indices began to increase marginally in mid-February, much later than previous seasons, and activity remained very low throughout, with community syndromic indicators not reaching the baseline warning threshold during the season. The peak GP influenza-like illness consultation rates in 2011/12 were the lowest since surveillance began in Northern Ireland in 2000. No one age-group appeared predominantly affected, with low levels of activity in all age groups, however, GP consultation rates increased in both children and adults.Influenza A (H3) was the predominant strain of the virus circulating, with small numbers of the influenza B strain circulating later in the season. Unlike the 2010/11 season when Influenza A (H1N1)2009 strain dominated in Northern Ireland, there were no detections of this subtype in 2011/12; virological activity generally corresponded to clinical activity.There were however, patients with confirmed influenza admitted to Intensive care units, across Northern Ireland during the season. Numbers were low, the average age of these patients increased compared with the previous season and one fatality was reported in this group.The proportion of over 65 year olds who received the 2011/12 seasonal influenza vaccine was 77.0%, and in those in a clinical risk group aged under 65 years was 81.7%, both of these vaccination uptake figures were a slight increase on the previous year. Influenza vaccine uptake in frontline healthcare workers also increased marginally this season to 20.8%, as did the proportion of pregnant women vaccinated during the season.

Pandemic Influenza Background (PDF 99 KB)

The Presence of highly pathogenicH5N1 avian influenza has been confirmed in birds in Turkey, Romania, Russia and Kazakhstan. There have been a total of 4 confirmed cases of human infection in Eastern/South Eastern Turkey that has resulted in 2 deaths. Background Avian influenza naturally circulates in wild waterfowl such as ducks and geese often causing little or no symptoms. Many other bird species are susceptible to infection with these influenza viruses and in many of these species it may cause severe disease associated with high mortality. Outbreaks associated with high bird mortality are called Highly Pathogenic Avian Influenza (HPAI) to distinguish them from less pathogenic influenza. In January 2004 avian influenza in poultry was confirmed in Vietnam. Subsequently, there have been very substantial outbreaks of avian influenza associated with high mortality affecting poultry in various countries throughout Asia including Vietnam, Thailand, China, Malaysia, Mongolia, North & South Korea, Cambodia, Indonesia, Laos and Japan. These outbreaks are caused by H5N1 subtype of influenza A virus, the same subtype (but not identical to the virus) that caused the outbreak in Hong Kong in 1997. åÊ

Surveillance of influenza in Northern Ireland 2010-11

This report describes influenza activity in Northern Ireland in the 2010-11 winter flu season period.

Surveillance of influenza in Northern Ireland 2012-2013

The 2012/13 influenza season started earlier than in 2011/12; however it lasted longer, with GP consultation rates being elevated for approximately four months. Clinical indices began to increase in late December and peaked in early January, with the only two instances of community syndromic indicators exceeding the baseline threshold occurring in this month. GP influenza-like illness consultation rates in 2012/13 were higher than those in the 2011/12 season for the majority of the season but remained low overall.Overall no one age-group appeared predominantly affected; however, older adults predominated during the peak period, with rates increasing in children during February. Rates for those aged 65 and over increased late in the season, and this was associated with influenza outbreaks in care homes for the elderly.

Surveillance of Influenza in Northern Ireland 2013-2014

�The 2013/14 influenza season started later than in 2012/13, it did not last as long and was noted at generally lower levels throughout than the previous season. Clinical indices began to increase in early January and peaked in mid-March, with community syndromic indicators not exceeding the baseline threshold at any time during the season. GP influenza-like illness consultation rates in 2013/14 were lower than those in the 2012/13 season for the majority of the season and remained low overall.Overall no one age group appeared predominantly affected with rates fluctuating throughout the season. The highest rate overall however was noted among the youngest age group during the peak period.

The 2014/15 influenza season was characterised by moderate levels of influenza activity.� Primary care consultation rates were higher than in 2013/14 for the majority of the season, although still low overall.� Activity seen in other surveillance was also higher than in 2013/14 year, and showed that the severity and impact of influenza was greater in 2014/15 and affected older age groups most frequently, with more reported respiratory outbreaks, patients with confirmed influenza admitted to Intensive Care Units/High Dependency Units and excess mortality in those over 65 years of a

Final Report of the National Narcolepsy Study Steering Committee

Final Report of the Final Report of the National Narcolepsy Study Steering Committee In August 2010 the Swedish pharmacovigilance authority reported that it was investigating six cases of narcolepsy reported by health care professionals as a possible adverse event following the use of Pandemrix vaccine, used during the H1N1 2009 pandemic. This was followed shortly by reports from the Finnish National Institute for Health and Welfare (THL) noting there had been a more than expected number of cases of narcolepsy in children and adolescents that year. On 23rd September, the Committee on Human Medicinal Products (CHMP) of the EMA concluded in its initial review of available data that the available evidence did not confirm a link but that more research was needed.   Click here to download PDF 1.1mb

PHA urges parents to get 'at risk' children vaccinated against seasonal flu

The Public Health Agency is urging Northern Ireland parents to make sure children in 'at risk' groups get their flu vaccine early.The message has been issued to parents and carers of children as the PHA's seasonal flu vaccination programme gets underway for 2011/12.It is very important that children with any condition that puts them more at risk of the complications of flu get the vaccine.These 'at risk' conditions include:chronic lung conditions such as asthma;chest infections that have required hospital admission;chronic heart conditions;chronic liver disease;chronic kidney disease;diabetes;lowered immunity due to disease or treatment such as steroids or cancer therapy;chronic neurological conditions such as stroke, multiple sclerosis or a condition that affects the nervous system, such as cerebral palsy;hereditary and degenerative diseases of the central nervous system or muscles.Children who attend special schools for severe learning or physical disabilities are considered to be particularly at risk, as well as those with other complex health needs.The PHA has written to principals of local special schools, as well as parents of children at these schools, to raise awareness of the importance of getting vaccinated early.Dr Richard Smithson, PHA Flu Vaccination Lead, said: "For many people, flu is a short, unpleasant illness, but it does not usually cause any serious problems. However, for others, it can have very serious complications including, in rare cases, being fatal."We have been particularly reminded over the last two winters that children with chronic neurological problems and other complex health needs are very vulnerable to these complications. We have seen children become very seriously ill and, tragically, there have even been a few deaths in children who attend special schools."For this reason, we recommend that all children who attend special schools for severe learning disability, and special schools for physical disability, are offered the flu vaccine early in the autumn, before the flu viruses start circulating."The vaccine is now available from GP surgeries and the PHA recommends that parents check arrangements with their own GP's surgery so that their child can get the jab.The earlier you get vaccinated the better, as it takes the body about 10-14 days after the jab to develop antibodies. These will then protect you against the same or similar viruses if the body is exposed to them. The vaccine contains three strains of the flu virus, which are considered the most likely to be circulating this winter, including the H1N1 (swine flu) virus."Your child needs to get the flu jab every year - the protection it gives only lasts for one winter, so even if they got it last year, they still need to get it this year," added Dr Smithson."Also, if your child has been diagnosed with flu or swine flu in the past couple of years, they will still need the jab this year as there are different types of flu that the jab will protect against. Getting the flu jab is the best way to protect your child against flu and we would strongly recommend that you arrange for them to have it."Although the vaccine gives good protection, no vaccine gives total protection, so if your child develops flu-like symptoms (such as fever, cough, aches and pains, and sore throat) you should contact your GP for advice. If your child has any of these symptoms, they should be kept at home until they feel better."For more information on seasonal flu, go to www.fluawareni.info and follow us on Facebook and Twitter.
