The flu is a common respiratory illness, but it can sometimes lead to serious health complications. Although many people recover within a few days, influenza can be more dangerous for young children, older adults, pregnant women and people with certain medical conditions. Understanding how the flu spreads, recognising its symptoms and getting recommended vaccinations can help you protect yourself and your family.
If you live in Dubai, learning about seasonal influenza prevention is an important part of maintaining your health throughout the year.
What Is the Flu (Influenza)?
Influenza, commonly known as the flu, is a contagious respiratory infection caused by influenza viruses. It primarily affects the nose, throat and sometimes the lungs. Symptoms can range from mild to severe, and some people may develop complications that require medical care.
The flu is different from the common cold. Although both illnesses can cause coughing, a sore throat and a runny nose, influenza often begins suddenly and may cause fever, body aches, headaches, chills and significant tiredness.
What Are the Common Symptoms of Influenza?
Flu symptoms can develop quickly and may vary from person to person. Common symptoms include:
- Fever or feeling feverish, although not everyone develops a fever
- Dry or persistent cough
- Sore throat
- Runny or blocked nose
- Headache
- Muscle and body aches
- Chills
- Fatigue and weakness
- Some people, particularly children, may also experience vomiting or diarrhoea.
Most people recover without serious complications, but symptoms can become severe in vulnerable individuals. If symptoms worsen, you have difficulty breathing or experience chest pain, seek prompt medical attention.
Why Is the Flu Vaccine Important?
It Helps Reduce the Risk of Flu
The flu vaccine prepares the immune system to recognise targeted influenza viruses. Protection varies depending on factors such as the vaccine formulation, the circulating viruses and an individual’s age and health.
Vaccination cannot guarantee that you will never catch the flu, but it can reduce your risk.
It Can Reduce the Risk of Severe Illness
Some people develop serious complications from influenza, including pneumonia or worsening of existing medical conditions. Vaccination can reduce the risk of severe outcomes, including hospitalisation, among vaccinated people.
It Helps Protect People at Higher Risk
Vaccination is particularly important for people who are more likely to experience flu-related complications. Protecting yourself may also help reduce the chance of passing influenza to vulnerable family members and other people in your community.
It Supports Healthier Communities
Seasonal influenza can affect families, schools, workplaces and healthcare services. Vaccination, together with everyday preventive measures, helps reduce the overall impact of the flu season.
It Is Recommended Every Flu Season
Protection from vaccination decreases over time, and influenza viruses evolve. An updated seasonal vaccine helps provide protection against the strains targeted for that season. Your healthcare provider can advise you on the appropriate timing based on current UAE recommendations.
Who Should Consider the Flu Vaccine?
- Young children: Children may be more vulnerable to complications from influenza.
- Older adults: The risk of severe illness generally increases with age.
- Pregnant women: Influenza can pose additional risks during pregnancy.
- People with chronic conditions: Those with certain heart, lung, kidney, liver or metabolic conditions may face a greater risk of complications.
- People with weakened immune systems: Some medical conditions and treatments can increase vulnerability to infections.
- Healthcare workers: Vaccination helps protect healthcare staff and the patients they care for.
How Can You Help Prevent the Flu?
- Wash your hands regularly with soap and water.
- Cover your mouth and nose when coughing or sneezing.
- Avoid close contact with people who are unwell where possible.
- Improve ventilation in enclosed spaces.
- Avoid touching your eyes, nose and mouth with unwashed hands.
- Stay home when you are ill, if possible, to reduce the risk of infecting others.
- Seek medical advice if symptoms become severe or you are at higher risk of complications.
FAQ
Is the flu vaccine necessary every year?
Seasonal vaccination is recommended because influenza viruses change over time and immunity decreases. Ask your healthcare provider about the vaccine recommended for the current season.
Can I get the flu after receiving the vaccine?
Yes. Vaccination does not provide complete protection, and other respiratory viruses can cause similar symptoms. However, the flu vaccine can reduce the risk of influenza and its potentially serious complications.
Does the flu vaccine cause the flu?
No. The injected flu vaccine does not cause influenza. Temporary side effects, such as a sore arm or mild fever, may occur as the body responds to vaccination.
Who is at higher risk of flu complications?
Young children, older adults, pregnant women and people with certain chronic medical conditions or weakened immune systems may be at greater risk. A healthcare professional can provide advice based on individual circumstances.
How long does it take for the flu vaccine to work?
It takes approximately two weeks for the body to develop an adequate immune response after vaccination. Protection can vary from person to person.
Can I get the flu vaccine if I have a cold?
It depends on how unwell you are. A mild illness may not always prevent vaccination, but a moderate or severe illness may mean it should be postponed. Ask a healthcare professional before proceeding.
Where can I ask about flu vaccination in Dubai?
