Understanding Flu

Understanding flu symptoms

  • Flu symptoms are intense and can appear suddenly;1 causing a fever, aching muscles, extreme tiredness, a stuffy nose, sore throat and a dry cough2
  • In serious cases, flu can lead to complications such as a painful ear infection, acute bronchitis and pneumonia2
  • Flu viruses are constantly changing, so vaccination is needed every year3,4
  • Flu is miserable for children and the family, with children taking up to seven days to recover,5 which can mean time off work for parents and affect childcare arrangements6

Understanding how the flu virus spreads

  • Flu is infectious and spreads easily to other people from coughs and sneezes, living on hands and surfaces for 24 hours7
  • Children are also more likely to spread flu as they stay infectious for longer8
  • A survey of more than 2,000 UK parents revealed that two thirds of children forget to wash their hands, a further 55% pick their noses and 48% don’t cover their mouths to sneeze or cough9

How to prevent the spread of flu

In addition to seeking vaccination for children, the NHS recommends that parents and carers minimise the spread of flu by:10

  • Teaching children about hygiene practices, including:
    – Using tissues to catch germs when coughing or sneezing, and throw away used tissues as quickly as possible
    – Washing hands effectively with warm water and soap
  • Cleaning household surfaces with anti-bacterial cleaners regularly

When is the best time to get vaccinated?

The best time to have a flu vaccine is in the autumn, from the beginning of October to the end of November.11

While it is impossible to predict how many cases of flu there will be each year or exactly when most people will get ill, we know that flu circulates every winter and generally peaks in December and January. You can have the flu vaccine later in the winter, although receiving the vaccine earlier will help to prevent the spread of flu.11
