Influenza, commonly known as the flu, is a highly contagious viral disease that affects the respiratory tract in humans, causing inflammation of the nose, throat, and lungs. While it can affect anyone, including healthy individuals, babies are particularly vulnerable to its severe consequences.
In this article, we will explore what influenza is, how babies catch the flu, why they are more at risk, complications from baby flu, symptoms, flu vaccination in babies, and essential preventive measures.
What is Influenza
Influenza, or the flu, is a respiratory virus caused by different strains of the flu virus, with influenza A and B being responsible for seasonal outbreaks and epidemics. It is highly contagious and spreads through droplets when an infected person coughs, sneezes or speaks.
The virus can also be transmitted indirectly through contact with contaminated surfaces. The flu can lead to various complications, including pneumonia and other respiratory infections.
How Do Babies Catch the Flu
Babies can catch the flu through exposure to the influenza virus. The virus is highly contagious and can spread from person to person, especially in crowded places or close contact settings. Common modes of transmission include:
-
Respiratory droplets: When an infected person coughs, sneezes, or talks, tiny droplets containing the virus can be released into the air. If a baby inhales these droplets or comes into contact with contaminated surfaces and then touches their face, they may contract the virus.
-
Close contact: Babies can catch the flu by being in close proximity to someone who has the virus. This often happens within families, childcare centers, or playgroups, where close interactions are frequent.
-
Contaminated surfaces: The flu virus can survive on surfaces for a few hours, so if a baby touches a contaminated object or surface and then touches their mouth, nose, or eyes, they may become infected.
-
Touching respiratory secretions: Babies can catch the flu by touching respiratory secretions from an infected person, such as touching used tissues or sharing toys with an infected child.
Why Are Babies More at Risk for Influenza

While everyone can catch the influenza virus, babies are more at risk because of the following reasons:
1. They have immature immune systems.
Infants’ immune systems are still developing, making it harder for them to fight off infections effectively.
2. They have limited immunity.
Babies have limited immunity to viruses like the flu because they haven’t been exposed to them before.
3. They are always in close contact with their caregivers.
Babies often have close contact with caregivers, siblings, and other children, increasing the likelihood of exposure to viruses.
4. They are not able to communicate their symptoms.
Infants cannot communicate their symptoms effectively, making it challenging for caregivers to recognize the early signs of flu.
5. They have limited protection.
Babies may not have received all their vaccinations yet, leaving them vulnerable to preventable diseases like the flu.
Symptoms of Flu in Babies
Recognising the symptoms of flu in babies is crucial for early intervention. Common signs include:
-
High Fever: A sudden high fever (temperature of 100.4 F or higher) is a typical flu symptom in babies.
-
Sore Throat: Infants may show signs of discomfort and have difficulty swallowing due to a sore throat.
-
Coughing: Persistent coughing is common in babies with the flu.
-
Headache: Babies may show signs of discomfort or irritability due to headaches.
-
Muscle Aches: Muscle pains may cause babies to be fussy and restless.
-
Stuffy Nose: Congestion and nasal discharge are common flu symptoms.
-
Loss of Appetite: Babies may refuse to feed due to the discomfort caused by flu symptoms.
-
Fatigue: Infants may be unusually tired and lethargic.
-
Weakness: The flu can cause weakness and decreased activity in babies.
Other signs to watch out for are the following
-
aversion to food
-
breathing problems
-
tearless crying
-
increased fussiness
-
less number of wet diapers than what is normal
How long does the flu last on a baby?
The duration of flu can vary depending on the severity of the infection and the overall health of the baby. In most cases, flu symptoms in babies can last for about a week or sometimes longer. During this period, infants may experience symptoms such as fever, cough, sore throat, body aches, runny or stuffy nose, and fatigue.
It is essential for parents to closely monitor their baby’s condition and seek medical attention if the symptoms persist or worsen.

Complications from Baby Flu
The flu is quite common and can usually be managed at home. However, if not treated in a timely manner, baby flu can lead to severe complications in infants, including:
-
Pneumonia: The infection can spread to the lungs and cause pneumonia, which can be life-threatening for infants.
-
Bronchitis: Inflammation of the airways, known as bronchitis, can lead to breathing difficulties and discomfort.
-
Ear Infection: Flu can increase the risk of ear infections, which are common in babies and can be painful.
-
Sinusitis: Infection of the nasal passages can lead to sinusitis, causing discomfort and congestion.
-
Meningitis: In rare cases, the flu virus can lead to meningitis, an inflammation of the brain lining.
- Myocarditis: Baby flu, caused by enterovirus infection, has been associated with severe myocarditis cases in neonates and infants
Treatment for Influenza in Babies
As parents or caregivers, it’s essential to know the best approaches to help your little one recover from the flu quickly and safely. Here’s a list of essential steps for treating baby flu:
At the first sign of flu symptoms in your baby, it’s crucial to seek medical guidance from a paediatrician. A healthcare professional can evaluate the severity of the illness and provide personalised recommendations for treatment based on your baby’s age and health condition.
One of the most important aspects of flu treatment is ensuring that your baby gets plenty of rest. Allow them to sleep and nap as much as they need to help their body fight off the virus effectively.
Offer your baby plenty of fluids, such as breast milk, formula, or water, to keep them hydrated. Proper hydration is essential to prevent dehydration, especially if the baby has a fever and is experiencing sweating or vomiting.
-
Use Fever-Reducing Medications
If your baby has a fever, consult your paediatrician about using appropriate fever-reducing medications like acetaminophen or ibuprofen. Always follow the recommended dosage and consult the healthcare provider before administering any medication.
For babies with nasal congestion, using saline drops can help clear their nasal passages and make breathing more comfortable. Consult your paediatrician before using any nasal drops or sprays.
-
Avoid Over-the-Counter Cough and Cold Medicines
Avoid giving over-the-counter cough and cold medicines to babies under the age of two, as they may not be safe for infants. Always consult with your paediatrician for suitable alternatives.
Continuously monitor your baby’s symptoms and watch for any signs of worsening illness. If symptoms persist or worsen, seek immediate medical attention.
Flu Vaccination in Babies

Vaccination is a crucial tool in protecting babies from the flu. The flu shot, also known as the flu vaccine, is recommended for all individuals aged 6 months and older, including babies. It is especially important for those at a higher risk of developing complications, such as babies under 5 years old.
The flu vaccine helps the body build immunity against specific flu strains, reducing the severity and risk of flu-related complications.
How to Prevent Baby Flu
Preventing the flu in babies involves a combination of vaccination and good hygiene practices. Here are some essential preventive measures:
-
Flu Vaccination: Ensure that your baby receives their flu vaccination as per the recommended schedule.
-
Hand Hygiene: Regularly wash your hands with soap and water for at least 20 seconds, especially before touching your baby or their belongings.
-
Avoid Close Contact: Limit contact with people who are sick and avoid crowded places during flu season.
-
