flu workplace prevention

Overview

Flu (short for influenza) is a common viral infection that attacks your nose, throat, and lungs. It spreads easily in places where people are close together, like offices, factories, shops, and other workplaces. Workplace prevention is about simple habits and policies that help stop the virus from passing between coworkers and from work to home.

Flu is common. Every year, millions of working-age adults get flu. Most recover within a week or two, but some get more serious complications, such as chest infections or pneumonia.

Flu can affect anyone, but it tends to be more serious for older adults, young children, pregnant women, and people with long-term health conditions. At work, people who are very tired, stressed, or not sleeping enough may be more likely to catch infections like flu.

Symptoms

Common symptoms

• Fever or feeling feverish and chills
• Cough
• Sore throat
• Runny or stuffy nose
• Muscle or body aches
• Headache
• Tiredness and weakness
• Some people may have vomiting and diarrhea (more common in children)

Symptoms in children

• High fever
• Cough and sore throat
• Irritability and feeling miserable
• Vomiting and diarrhea (more common than in adults)
• Ear pain or signs of an ear infection

Symptoms in older adults

• The classic fever may be less obvious or even absent.
• Confusion or unusual drowsiness
• Feeling weak or less steady on their feet
• Worsening of existing conditions, such as heart failure or lung disease
• Loss of appetite and reduced activity

Causes

Main causes

• Influenza viruses, especially types A and B, cause flu.
• Flu spreads mainly by tiny droplets when an infected person coughs, sneezes, or talks.
• You can also catch flu by touching surfaces or objects that have the virus on them, then touching your eyes, nose, or mouth.

Risk factors

• Working in crowded indoor spaces
• Close contact with coworkers, customers, or clients who may be sick
• Poor hand hygiene
• Touching your face often
• Not getting the annual flu vaccine
• Being very stressed, overtired, or having a weakened immune system

When to see a doctor

See a doctor urgently if:

• If you have trouble breathing, chest pain, confusion, or severe weakness, call emergency services immediately.
• If your fever lasts more than 3 days or your symptoms get much worse, contact a healthcare provider the same day.

Book a routine appointment if:

• If you have flu symptoms and you are at higher risk of complications (for example, you are older, pregnant, or have a long-term health condition), contact your healthcare provider within a day or two.
• If you are returning to work and still have a bad cough or feel very weak, you may want to get a check-up.

Diagnosis

A healthcare provider often diagnoses flu based on your symptoms, especially during flu season. In some cases — such as for people in high-risk groups or when the illness is severe — they may recommend a test.

Tests that may be done

• A swab test from the nose or throat, which checks for flu virus
• A Rapid Influenza Diagnostic Test (RIDT), which gives a result in about 15 minutes but can be less accurate
• More sensitive PCR tests, which are usually done in a lab and take a few hours to a day

What to expect at your appointment

Your doctor or nurse will ask about your symptoms and may check your temperature, breathing, and heart rate. If you have flu, you may be advised to rest, drink plenty of fluids, stay away from work until you feel better, and possibly take prescription medication if you are in a high-risk group. They will also tell you warning signs to watch for.

Treatment

Flu is caused by a virus, so antibiotics do not work. For most people, treatment focuses on relieving symptoms and letting the body heal. Some people who are high-risk or seek care very early may be prescribed antiviral medicine, which can shorten the illness, but this must be started quickly by a qualified healthcare provider.

Self-care at home

• Rest and allow yourself time to recover — do not rush back to work
• Drink plenty of fluids like water, broth, or herbal tea
• Use a humidifier or take a warm shower to ease cough and congestion
• Soothe a sore throat with warm salt water gargles or lozenges
• Use over-the-counter pain and fever relief as directed by a pharmacist or healthcare provider
• Gently blow your nose and wash your hands often

Medical treatments

A healthcare provider may offer prescription antiviral medicines, especially if you are at high risk or you are seen within the first 48 hours of symptoms. These are not a cure, but they can make the illness shorter and less severe. There are also over-the-counter symptom relievers for fever, aches, and congestion — ask your pharmacist which are safe for you.

Living with this condition

When you have flu, stay home from work and avoid close contact with others, even if you feel well enough to work. If you must be around people, wear a mask, cough into a tissue or your elbow, and wash your hands often. Let your workplace know about your situation and follow their sick-leave policy.

Lifestyle tips

• Get plenty of sleep and avoid heavy activity while recovering
• Keep your nose and mouth covered when coughing or sneezing
• Clean and disinfect surfaces you touch often, like phones, keyboards, and doorknobs
• Keep a safe distance from others if you are still coughing or sneezing
• Return to work only when you are fit to do so and no longer likely to spread the virus

Diet and exercise

Eat light, nutritious meals if you have an appetite — soups and broths are especially good. Avoid alcohol and too much caffeine while ill. Once you feel better, gradually ease back into physical activity; gentle walking is fine, but wait until your energy returns.

Mental health and emotional wellbeing

It is normal to feel frustrated, anxious, or low when you are sick and unable to work. Give yourself permission to rest, keep in touch with loved ones by phone or video, and do calming activities like listening to music or reading. If low mood persists after your symptoms improve, speak to a healthcare provider.

Prevention

Flu vaccination is the single best way to reduce your risk of getting flu and spreading it. Workplace prevention also includes good hand hygiene, covering coughs and sneezes, staying home when sick, and keeping shared spaces clean.

Vaccines

The flu vaccine is updated every year and is recommended for almost everyone aged 6 months and older, including working adults. Many employers offer flu vaccines at work or cover the cost at local pharmacies. Ask your employer, pharmacist, or healthcare provider about getting your annual flu vaccine.

Complications

If left untreated

• Ear infections and sinus infections
• Bronchitis (inflammation of the airways)
• Pneumonia, which can be severe
• Worsening of existing health conditions like asthma, diabetes, or heart disease
• In rare cases, inflammation of the brain (encephalitis) or multiple organ failure

Long-term outlook

Most people who get flu recover completely in 1 to 2 weeks with rest and fluids. More serious complications are uncommon, and treatment works best when started early, especially for people at higher risk. A healthy recovery is the usual outcome. And with workplace prevention practices, you reduce the chance of spreading it to others.
