Influenza, commonly known as the flu, is a contagious respiratory illness caused by influenza viruses. While it often peaks during the winter months, influenza can circulate year-round. Parents need to understand how influenza spreads, recognize its symptoms, know how to treat it, and most importantly, how to prevent it to keep their children healthy.
What is Influenza?
Influenza is a viral infection that primarily affects the respiratory system, including the nose, throat, and lungs. It is caused by different influenza virus strains, with two main types—Influenza A and Influenza B—responsible for most flu cases. Influenza spreads quickly from person to person through respiratory droplets that are released when someone coughs, sneezes, or talks.
While the flu can affect people of all ages, children under 5, especially those under 2, and children with chronic health conditions like asthma or diabetes are at a higher risk for complications from the flu.
How Does Influenza Spread?
Influenza is highly contagious and spreads mainly through respiratory droplets. When someone with the flu coughs, sneezes, or talks, tiny droplets containing the virus can land in the mouths or noses of nearby people or be inhaled into the lungs. Less frequently, the virus can spread when a person touches a surface with the flu virus (such as a doorknob, toy, or table) and then touches their mouth, nose, or eyes.
Children, in particular, are more susceptible to catching the flu in environments like schools, daycares, and playgrounds, where close contact with others is expected.
Symptoms of Influenza
Flu symptoms can come on suddenly and vary in severity. Common signs and symptoms of the flu in children include:
High Fever: Often over 102°F (39°C)
Cough: A dry, persistent cough
Sore Throat: Often accompanied by a scratchy or painful throat
Runny or Stuffy Nose: Congestion and nasal discharge are common, especially in younger children.
Body Aches: Muscle or body aches, particularly in the back, legs, and arms.
Headache: Often severe and accompanied by fatigue.
Chills: Shivering and feeling cold, even when the child has a high fever.
Fatigue: A general feeling of tiredness or weakness.
Vomiting and Diarrhea: Gastrointestinal symptoms are more common in children than adults with the flu.
The flu can often be confused with the common cold, but influenza symptoms tend to be more severe and come on much more suddenly than cold symptoms.
Potential Complications
While most children recover from the flu within a week or two without any lasting problems, some can develop complications, which can be severe. Children under the age of 5 and those with underlying health conditions are more vulnerable to flu-related complications, which may include:
Pneumonia: A lung infection that can be life-threatening.
Bronchitis: Inflammation of the airways in the lungs.
Ear Infections: Flu can lead to secondary infections, such as ear infections.
Sinus Infections: Persistent congestion can result in bacterial sinus infections.
Worsening of Chronic Health Conditions: Children with asthma, diabetes, or heart conditions may see their symptoms worsen when they have the flu.
In severe cases, the flu can lead to hospitalization and, in rare cases, death, particularly in young children, the elderly, or those with weakened immune systems.
Treatment for Influenza
If you suspect your child has the flu, it’s essential to consult with a healthcare provider, especially if your child is in a high-risk group or showing severe symptoms. Treatment typically focuses on relieving symptoms and supporting recovery. Here are some ways to manage the flu at home:
Rest and Hydration:
Ensure your child gets plenty of rest to help the body fight the infection.
Encourage them to drink fluids like water, clear soups, or electrolyte solutions to prevent dehydration, especially if they have a fever, vomiting, or diarrhea.
Fever and Pain Relief:
Acetaminophen (Tylenol) or ibuprofen (Advil) can reduce fever, body aches, and headaches.
Never give aspirin to children due to the risk of Reye’s syndrome, a rare but severe illness.
Antiviral Medications:
Your child’s doctor may sometimes prescribe antiviral medications such as oseltamivir (Tamiflu).
These medications work best if given within the first 48 hours of symptom onset and can shorten the duration of the illness and reduce the severity of symptoms. Antivirals are particularly important for children at high risk of complications.
Comfort Measures:
A humidifier adds moisture to the air, which can help with a dry, sore throat and nasal congestion.
Use saline nose drops or a nasal aspirator for younger children to help clear stuffy noses.
When to Seek Medical Attention
While most children recover from the flu without significant issues, specific symptoms warrant immediate medical attention. Call your doctor or seek emergency care if your child has:
Difficulty breathing or rapid breathing
A bluish or grayish skin color
Severe chest pain or persistent pressure
Not drinking enough fluids or signs of dehydration (dry mouth, no tears when crying, very little urine output)
Severe or persistent vomiting
Seizures
Confusion or difficulty waking up
Fever above 104°F (40°C) in children older than three months or any fever in a baby under three months
Prevention of Influenza
The best way to protect your child from the flu is through vaccination. The flu vaccine is recommended for all children six months and older and is updated annually to protect against the most common strains of the virus. Here are essential preventive measures:
Flu Vaccine:
Annual Flu Shot: The Centers for Disease Control and Prevention (CDC) recommends that everyone six months and older get vaccinated against the flu each year. The vaccine is essential for young children, elderly individuals, and people with chronic health conditions.
Nasal Spray Vaccine: In some cases, children may be eligible for the nasal spray flu vaccine, a live, attenuated form of the flu virus. It’s typically recommended for healthy children over the age of 2.
Good Hygiene Practices:
Frequent Handwashing: Teach your child to wash their hands regularly with soap and water for at least 20 seconds, especially after coughing, sneezing, or touching their face.
Cough and Sneeze Etiquette: Encourage your child to cover their mouth and nose with a tissue or their elbow when coughing or sneezing to prevent the spread of germs.
Avoiding Contact with Sick Individuals:
Try to minimize your child’s exposure to individuals who are sick with the flu.
If your child is sick, keep them home from school or daycare to prevent spreading the illness to others.
Disinfect Commonly Touched Surfaces:
Regularly disinfect toys, doorknobs, and other frequently touched surfaces in your home, especially if someone is sick.
Conclusion:
Influenza is a common but potentially severe illness that affects children every year. Understanding the symptoms and seeking timely treatment can help your child recover quickly. Most importantly, preventive measures like vaccination and good hygiene can significantly reduce your child’s flu risk. If you have any concerns about the flu or the flu vaccine, talk to your healthcare provider to ensure your child is protected.
