flu risk reduction

Overview

The flu (short for influenza) is a common viral infection that affects your nose, throat, and lungs. It spreads easily from person to person. Flu risk reduction means taking simple steps to lower your chances of getting the flu or passing it to others.

Yes, the flu is very common. It happens every year, usually in the autumn and winter months in many parts of the world.

Anyone can get the flu, but young children, older adults, pregnant women, and people with long-term health conditions are more likely to become seriously ill.

Symptoms

Common symptoms

• Fever or feeling feverish
• Cough
• Sore throat
• Runny or stuffy nose
• Body aches or muscle pain
• Headache
• Feeling very tired

Symptoms in children

• All the common symptoms can appear, plus:
• Nausea, vomiting, or diarrhea
• Being fussy or less active than usual

Symptoms in older adults

• May have a lower fever or no fever at all
• Confusion or changes in thinking
• Weakness or extreme tiredness
• Worsening of other health conditions

Causes

Main causes

• Infection with the influenza virus, mainly types A and B
• Breathing in droplets from an infected person's cough, sneeze, or speech
• Touching your eyes, nose, or mouth after touching surfaces with the virus on them

Risk factors

• Not getting the annual flu vaccine
• Living or working in crowded places, like schools or care homes
• Being in close contact with someone who has the flu
• Having a weakened immune system
• Being younger than 5 or older than 65
• Being pregnant

When to see a doctor

See a doctor urgently if:

• If you or your child have any emergency symptoms, call your local emergency number right away.
• If you are at high risk of complications (such as older adults, young children, pregnant women, or people with chronic conditions) and you think you have the flu, contact your healthcare provider within the first day or two of symptoms.

Book a routine appointment if:

• If you have flu symptoms and are concerned, or if symptoms last longer than a week
• If your fever goes away but then comes back
• If you have a health condition and are unsure whether you need a check-up

Diagnosis

A doctor can often tell if you have the flu by asking about your symptoms and doing a simple exam. In some cases, they may take a swab from your nose or throat to confirm the virus.

Tests that may be done

• A swab of the nose or throat (called a rapid influenza test)
• A polymerase chain reaction (PCR) test, which is more accurate and may take longer
• In rare cases, a chest X-ray if the doctor suspects pneumonia

What to expect at your appointment

The testing process is quick and usually painless. The doctor will discuss your symptoms and let you know whether you have the flu or another illness. They will also explain how to manage your symptoms at home and when to seek care again.

Treatment

Treatment for the flu focuses on relieving symptoms and supporting your body's natural recovery. Most people get better at home without special medical treatment.

Self-care at home

• Rest and sleep as much as possible
• Drink plenty of fluids like water, warm soups, or herbal teas
• Take over-the-counter pain and fever reducers (if appropriate for you)
• Stay home until you feel better to avoid spreading the virus
• Use a cool-mist humidifier or take a warm bath to ease cough and congestion

Medical treatments

For some people, especially those at high risk of complications, a doctor may prescribe antiviral medicines. These are not cures, but they can reduce the severity of illness and shorten the time you are sick. They work best when started early, usually within the first two days of symptoms. Only a healthcare provider can decide if these are right for you.

Living with this condition

While you recover from the flu, take it easy. Rest, stay home, and keep up with fluids. Clean surfaces you touch often and wash your hands regularly to avoid passing the virus to others.

Lifestyle tips

• Wash your hands often with soap and water for at least 20 seconds
• Use hand sanitizer when soap is not available
• Avoid touching your face, especially your eyes, nose, and mouth
• Clean and disinfect common surfaces like doorknobs and phones
• Cover your nose and mouth with a tissue or your elbow when coughing or sneezing

Diet and exercise

Eat light, easy-to-digest foods like soups, toast, and fruits. You do not need to force yourself to eat a lot. Gentle movement, like walking around the house, is fine but do not overdo it until your energy returns.

Mental health and emotional wellbeing

Feeling unwell can make you feel frustrated or lonely. It is normal to feel low while sick. Give yourself time to recover and reach out to loved ones by phone or video if you cannot be together.

Prevention

Yes, you can greatly reduce your risk of the flu by getting vaccinated every year, washing your hands often, and avoiding close contact with sick people.

Vaccines

The seasonal flu vaccine is recommended for everyone aged 6 months and older, especially those at higher risk. It is updated each year to match the most common flu strains. The vaccine cannot give you the flu and is the best way to protect yourself and your community.

Complications

If left untreated

• Pneumonia (a lung infection)
• Worsening of existing conditions like asthma, diabetes, or heart disease
• Ear infections or sinus infections
• Dehydration

Long-term outlook

The outlook for most people with the flu is good. With rest and fluids, most recover in one to two weeks. For those who are at higher risk, early medical care and antiviral treatment can make a big difference. Getting the flu vaccine each year is the most hopeful step you can take to protect your health.
