Flu Season in UAE: Symptoms, Prevention Tips & When to See a Doctor

As the UAE’s weather turns cooler, influenza—commonly called the flu—often becomes a greater health concern. More time spent indoors, closer contact in schools, workplaces, and social settings, and increased travel can make it easier for the virus to spread from person to person.

Although flu and the common cold can share symptoms such as a runny nose, sore throat, cough, and fatigue, they are not the same. Flu typically comes on more suddenly and may cause a high fever, body aches, chills, marked tiredness, and a more severe cough. For some people—particularly young children, older adults, pregnant women, and those with chronic health conditions—it can also lead to serious complications.

Recognising flu symptoms early and taking prompt steps, such as staying home when unwell, limiting close contact with others, and seeking medical advice when symptoms are severe or persistent, can help reduce transmission and support a safer recovery.

What Is Seasonal Flu?

Seasonal flu, or influenza, is a contagious viral infection that affects the respiratory system, including the nose, throat and sometimes the lungs. The main viruses responsible are influenza A and influenza B. Flu spreads primarily through respiratory droplets and small particles released when an infected person coughs, sneezes, talks or breathes. It can also spread through close contact with someone who is unwell, or when contaminated hands touch the eyes, nose or mouth.

Symptoms typically develop within 1 to 4 days after exposure, often starting suddenly with fever, cough, sore throat, body aches, headache and fatigue. In uncomplicated cases, most symptoms improve within around 3 to 7 days, although cough and tiredness may last longer for some people.

Flu vs. Common Cold: What's the Difference?

Flu and the common cold are both respiratory illnesses, but flu symptoms are generally more intense and tend to appear more abruptly. A cold is usually milder and often develops gradually, with symptoms such as a runny or blocked nose more commonly reported.

Symptom	Flu	Common cold
Onset	Often sudden	Usually gradual
Fever	Common	Less common
Body aches	Often prominent	Usually mild
Fatigue	Can be significant	Usually milder
Cough	Often dry and persistent	Usually milder

Symptoms can overlap, so symptoms alone do not always confirm whether someone has the flu or a cold. Testing and clinical assessment may be needed, particularly when symptoms are severe, persistent or worsening.

Common Flu Symptoms to Watch For

Flu symptoms often come on suddenly and can feel more intense than those of a common cold. Common signs include fever or feeling feverish, chills, a dry or persistent cough, sore throat, runny or blocked nose, headache, muscle and joint aches, and marked fatigue or weakness. While fever and body aches may improve within several days, a cough and tiredness can sometimes continue for two weeks or longer.

Flu Symptoms in Children

Children can develop many of the same flu symptoms as adults, including fever, cough, sore throat, runny or blocked nose, and fatigue. They may also seem unusually irritable or sleepy, have a reduced appetite, or be less interested in feeding and playing. Vomiting or diarrhoea can occur with flu and is more common in children than in adults; importantly, not every child with flu will develop a fever.

How Long Does the Flu Last?

Flu recovery varies, but most people with uncomplicated influenza begin to improve within about a week. Symptoms often start suddenly after an incubation period of 1 to 4 days following exposure.

Typical timeline	What to expect
Days 1–2	Symptoms can appear abruptly, often with fever, chills, body aches, headache, cough and marked fatigue.
Days 3–5	Fever, aches and exhaustion may be at their most intense.
Around 1 week	Most people begin to feel significantly better as the acute symptoms settle.
Afterwards	A cough, low energy and tiredness may linger for two weeks or longer in some people.

Recovery may take longer—and the risk of flu-related complications can be higher—for young children, older adults, pregnant women, and people with underlying health conditions or weakened immune systems. People in these groups should seek medical advice early if flu symptoms develop, particularly if symptoms are severe, worsening or accompanied by breathing difficulty.

Who Is More at Risk of Flu Complications?

Anyone can become seriously unwell with influenza, but some people are more likely to develop complications such as pneumonia, worsening of an existing condition or a need for hospital care. Flu symptoms should be taken particularly seriously in:

Children under 5, especially those under 2
Adults aged 65 and over
Pregnant women and women in the first two weeks after delivery
People with asthma or chronic respiratory conditions, such as COPD
People with heart disease or diabetes
People with weakened immune systems due to a medical condition or immune-suppressing treatment.

These groups should seek medical advice early if they develop flu symptoms, particularly if symptoms are severe, getting worse, or include shortness of breath, chest pain, confusion or signs of dehydration.

Healthcare workers and others with frequent close exposure to infections are not automatically at higher risk of severe flu solely because of their job, but they may be more likely to encounter the virus and could pass it to vulnerable patients or household members. Preventive measures, including seasonal flu vaccination and staying home when unwell, are therefore especially important.

How to Prevent the Flu During Flu Season UAE

Get Your Annual Flu Vaccine

Annual flu vaccination is the most effective way to reduce the risk of influenza and its potentially serious complications. Because influenza viruses continually change, vaccine formulations are reviewed and updated each season to target the strains expected to circulate. Vaccination may not prevent every infection, but it can reduce the likelihood of illness and help lessen the severity of disease if someone does get the flu. It takes around two weeks after vaccination for protective antibodies to develop, so it is best to get vaccinated ahead of periods of increased flu activity.

Practice Everyday Prevention

Alongside vaccination, everyday precautions can help reduce the spread of flu and other respiratory infections:

Wash hands regularly with soap and water, or use hand sanitiser when handwashing is not available.
Cover the mouth and nose with a tissue or elbow when coughing or sneezing.
Dispose of used tissues promptly and wash hands afterwards.
Avoid close contact with people who are unwell where possible.
Stay home and limit contact with others when sick.
Improve airflow in indoor spaces by opening windows or using suitable ventilation where feasible.
Avoid crowded, poorly ventilated indoor settings when respiratory illnesses are circulating.
Consider wearing a well-fitting mask if you have respiratory symptoms and need to be around other people, especially those at higher risk of complications.

Together, these measures can reduce exposure to respiratory particles and help protect vulnerable people in homes, workplaces, schools and healthcare settings.

What to Do If You Get the Flu

For mild flu symptoms, focus on rest, fluids and limiting the risk of passing the virus to others. Stay home where possible, minimise close contact with others, and monitor whether symptoms are steadily improving or becoming more severe. Fever, aches and discomfort can often be managed with appropriate over-the-counter symptom relief, following the product instructions and advice from a pharmacist or clinician. Avoid giving aspirin-containing medicines to children or teenagers unless specifically advised by a clinician.

Seek medical advice promptly if you are at higher risk of complications, if symptoms are severe or worsening, or if there is shortness of breath, chest pain, confusion, persistent dehydration, or difficulty waking or staying awake. In general, return to normal activities only once symptoms are improving overall and you have been fever-free for at least 24 hours without using fever-reducing medicines.

What About Antivirals?

Antiviral medicines are prescription treatments that act against influenza viruses. They are different from antibiotics and may be recommended by a doctor for people who are hospitalized, very unwell, or at higher risk of flu complications—including young children, older adults, pregnant women and people with certain chronic health conditions. When appropriate, antivirals work best when started as early as possible, ideally within 48 hours of symptom onset; however, they can still be beneficial later in severe or high-risk cases.

Antibiotics do not treat influenza because flu is caused by a virus, not bacteria. They may only be prescribed if a clinician identifies a separate bacterial infection or complication.

When Should You See a Doctor for the Flu?

Most people with uncomplicated flu recover with rest, fluids and symptom management. However, influenza can sometimes lead to complications—including pneumonia—or worsen existing conditions such as asthma, heart disease or diabetes. It is important not to dismiss symptoms that feel severe, are not improving, or return after seeming to settle.

Speak to a Doctor If:

Symptoms are getting worse rather than gradually improving.
A fever persists, returns after improving, or is accompanied by worsening cough.
You have significant breathing difficulties, wheezing or shortness of breath.
You develop chest pain or pressure.
You feel unusually weak, confused, faint, very drowsy or difficult to wake.
You cannot keep fluids down, are vomiting repeatedly, or have signs of dehydration.
You are in a higher-risk group, including young children, adults aged 65 and over, pregnant women, or people with chronic health conditions or weakened immunity.
Symptoms improve and then suddenly worsen.
You are concerned about a child, an older family member or a pregnant person.

When to Seek Urgent Medical Care
Seek urgent medical care immediately for:

Severe difficulty breathing or rapid breathing
Persistent chest pain or pressure
Bluish or grey lips, face or skin
Significant confusion, inability to stay awake or reduced responsiveness
Signs of severe dehydration, such as very little urine, a very dry mouth, or no tears when crying in a child
Rapid deterioration or a sudden worsening of symptoms

In children, urgent warning signs can also include working hard to breathe, ribs pulling in with each breath, refusing fluids, or not interacting normally when awake.

Flu Season UAE: What You Should Know

In the UAE, the Ministry of Health and Prevention’s national seasonal flu awareness campaign identifies September to March as its official period for flu awareness and prevention. The campaign encourages vaccination, good hygiene and early action to reduce the spread of influenza and protect people who are more vulnerable to complications.

Prevention becomes particularly important as routines shift during the cooler months. Children return to school, families spend more time together indoors, and workplaces and social venues may be busier—creating more opportunities for respiratory viruses to pass between people in close-contact settings. Better ventilation can help reduce the concentration of respiratory virus particles indoors, especially in crowded spaces.

Vaccination is particularly important for families with young children, older adults, pregnant women and people living with chronic conditions such as asthma, diabetes or heart disease. Speak with a healthcare professional about the most appropriate time to receive the seasonal influenza vaccine, and about testing or antiviral treatment options if flu symptoms develop—especially for anyone at higher risk of complications.
