During the 2019/20 influenza season, in General Practice (GP) registered patients, in England:1

16 to 65 age group icon

55%*
of people aged 16-65 years, with chronic medical conditions**

Over 65 icon

28%*
of people aged over 65 years

Pregnancy icon

56%*
of pregnant women (both healthy and at-risk)

WERE NOT VACCINATED AGAINST INFLUENZA1

*Median vaccine uptake rates in GP registered patients in England, as reported between 1st September 2019 and 29th February 2020 (based on a 99.3% survey response rate).

**Patients with clinical risk as listed in the Green Book (diabetes, chronic kidney disease, immunosuppression, chronic neurological disease, chronic respiratory disease, chronic heart disease, chronic liver disease, asplenia or dysfunction of the spleen and morbid obesity).



The burden of influenza continues to pose a challenge:2-4

Hospital icon

39,670 hospital admissions recorded during the 2018/19 flu season alone2

Hospital bed icon

286,256 bed days resulting from secondary care admissions during the 2018/19 flu season2

Cardiovascular disease icon

Influenza may increase the risk of heart attack by up to 10-fold in the 1–3 days following a confirmed infection3

Vaccination icon

“In light of the risk of flu and COVID-19 co-circulating this winter, the national flu immunisation programme will be absolutely essential in helping to protect vulnerable people and supporting the resilience of the health and care system”4

 

 

IN THE UK, INFLUENZA OCCURS MOST OFTEN IN WINTER, AND PEAKS BETWEEN DECEMBER AND MARCH, ALTHOUGH OUTBREAKS MAY OCCUR AS EARLY AS OCTOBER, OR AS LATE AS MAY5

 

Virus detections and hospitalisations 2019 2020 season


INFLUENZA VIRUS DETECTION IN ENGLAND
* AND PROPORTION OF HOSPITILISATIONS DUE TO  INFLUENZA,** AS REPORTED DURING THE 2019/20 FLU SEASON.6,7


*Influenza virus detections in sentinel-source specimens by type and subtype, cumulative for week 40 to 20.

**Based on hospitalised laboratory-confirmed influenza cases in ICUs.


Trends suggest that during the 2019/20 flu season, cases peaked in December.6

 

EVEN THOUGH THE INFLUENZA SEASON HAS ALREADY STARTED, WHILE FLU VIRUSES ARE CIRCULATING, YOU CAN STILL HELP PROTECT ELIGIBLE PATIENTS WITH AN INFLUENZA VACCINATION8

It takes up to two weeks to be protected after an influenza vaccine.9
