Flu is a highly contagious virus which is spread by germs from coughs and sneezes. These germs have the ability to live on hands and surfaces for 24 hours. There has been an increase in flu cases in the UK over the last few weeks, and in some areas the spread of the virus had led to the closure of schools. From January 19, Redbridge Community School in Southampton was shut for three days after more than 300 pupils and staff fell ill.
Oasis Academy Mayfield in the same city has now been forced to shut after an “unprecedented level” of staff and students became sick, reports the BBC.
So how do you know if you have the flu – what are the symptoms?
The NHS lists the following signs, detailing that they can come on very quickly:
- A sudden fever – a temperature of 38C or above
- An aching body
- Feeling tired or exhausted
- A dry cough
- A sore throat
- A headache
- Difficulty sleeping
- Loss of appetite
- Diarrhoea or tummy pain
- Nausea and being sick
How can you prevent flu and stop it spreading?
One of the best ways to prevent flu is to get the flu jab.
Dr Nicola Read, clinical fellow at Bupa UK, says anyone in the UK can have the flu vaccine, but some groups of people are specifically advised to have one.
She explains: “This is because they’re either at a higher risk of catching flu, or likely to become ore unwell if they do catch flu.”
The people that fall into this category are:
- People aged 65 and over
- Pregnant women
- Children aged between six months and five years
- People with a health condition such as diabetes, heart disease, kidney disease or asthma
- People with a weakened immune system
Dr Read advises: “If you’re part of these at-risk groups, you’ll be eligible for a free flu vaccine through the NHS.
“It’s also recommended that you have the flu vaccine if you’re a healthcare professional who regularly sees patients, or if you’re a carer for a vulnerable person. This is to prevent you from passing the virus on to them or being unable to care for them should you become ill.
“You can have the flu vaccine if you’re pregnant, but be sure to let your doctor or nurse know first so they can explain the precautions to you.
“If you think you already have the flu or are unwell, it’s best to wait until you’re feeling better to have the vaccine.
“You shouldn’t have the flu vaccine if you’ve had a serious allergic reaction to the vaccine in the past. If you’re allergic to eggs or egg products, you might not be able to have the usual flu vaccine. There are different vaccines available, so speak to your doctor or nurse for advice.”
To avoid the flu spreading make sure to wash your hands with warm water and soap, use tissues to trap germs when you cough or sneeze, and bin used tissues as quickly as possible.
Taking these precautions can help you prevent flu, but some experts also recommend eating certain foods.
