The dataset provides a list of the wild birds identified and submitted under both passive and active (targeted) surveillance programmes in Great Britain for testing for Avian Influenza by the Animal and Plant Health Agency (APHA). The main emphasis in the surveillance programmes is on patrols of designated reserves by skilled wild bird ecologists and wardens to locate “found dead” wild birds, including “mass mortality incidents”. These Warden Patrols continue all-year-round, and are also seasonally targeted in the winter and spring periods (October to March) each year. Members of the public are also asked to remain vigilant for mass bird mortality incidents occurring in any location in GB and report these to the Defra Helpline. The criteria for a “mass mortality incident” are five or more wild birds of any species at any location in England, Scotland and Wales. The dataset contains information on the identity of the bird, the date, location and which samples were taken from those birds and their test results. Please Note: The location represents a 10km x 10km square in which the bird was found. Location data is provided by the submitter and is not verified and, if no location information is available, the location of the testing laboratory may be used. For further information and explanations of the data included in this dataset, please see the data dictionary available for download alongside this dataset.

Very different influenza seasons have been observed from 2008/09–2011/12 in England and Wales, with the reported burden varying overall and by age group. The objective of this study was to estimate the impact of influenza on all-cause and cause-specific mortality during this period. Age-specific generalised linear regression models fitted with an identity link were developed, modelling weekly influenza activity through multiplying clinical influenza-like illness consultation rates with proportion of samples positive for influenza A or B. To adjust for confounding factors, a similar activity indicator was calculated for Respiratory Syncytial Virus. Extreme temperature and seasonal trend were controlled for. Following a severe influenza season in 2008/09 in 65+yr olds (estimated excess of 13,058 influenza A all-cause deaths), attributed all-cause mortality was not significant during the 2009 pandemic in this age group and comparatively low levels of influenza A mortality were seen in post-pandemic seasons. The age shift of the burden of seasonal influenza from the elderly to young adults during the pandemic continued into 2010/11; a comparatively larger impact was seen with the same circulating A(H1N1)pdm09 strain, with the burden of influenza A all-cause excess mortality in 15–64 yr olds the largest reported during 2008/09–2011/12 (436 deaths in 15–44 yr olds and 1,274 in 45–64 yr olds). On average, 76% of seasonal influenza A all-age attributable deaths had a cardiovascular or respiratory cause recorded (average of 5,849 influenza A deaths per season), with nearly a quarter reported for other causes (average of 1,770 influenza A deaths per season), highlighting the importance of all-cause as well as cause-specific estimates. No significant influenza B attributable mortality was detected by season, cause or age group. This analysis forms part of the preparatory work to establish a routine mortality monitoring system ahead of introduction of the UK universal childhood seasonal influenza vaccination programme in 2013/14.

The information in this bulletin about immunisation statistics in England comes from Public Health England (PHE). Information on childhood immunisation coverage at ages 1, 2 and 5 years is collected through the Cover of Vaccination Evaluated Rapidly (COVER) data collection for Primary Care Trusts (PCTs). Information on persons aged 65 and over immunised against seasonal flu is collected from GPs through PHE's ImmForm system.

Influenza, commonly known as the flu, is a contagious respiratory illness caused by influenza viruses resulting in mild to severe influenza-like illness. Seasonal influenza affects persons of all ages. Each year, between 5% and 15% of the world's population is affected by seasonal influenza (WHO, 2013). Complications of influenza include pneumonia, bronchitis, ear infections, sinus infections, and worsening of chronic medical conditions such as congestive heart failure, asthma, or diabetes. Vaccination has been shown to reduce influenza morbidity and mortality and high economic burden associated with influenza illness. Read More

The UK Health Security Agency (UKHSA) weekly all-cause mortality surveillance helps to detect and report significant weekly excess mortality (deaths) above normal seasonal levels. This report does not assess general trends in death rates or link excess death figures to particular factors.
Excess mortality is defined as a significant number of deaths reported over that expected for a given week in the year, allowing for weekly variation in the number of deaths. UKHSA investigates any spikes seen which may inform public health actions.
Reports are currently published weekly. In previous years, reports ran from October to September. Since 2021, reports run from mid-July to mid-July each year. This change is to align with the reports for the National flu and COVID-19 weekly surveillance report.
