Understanding RSV Season: What You Need to Know for Your Family

Respiratory Syncytial Virus (RSV) is a common respiratory virus that affects people of all ages but can be especially serious for infants, young children, and older adults. Each year, RSV season brings a surge in infections, leading to increased doctor visits, hospitalizations, and concerns among families. Understanding what RSV season means, how the virus spreads, and what steps you can take to protect your loved ones is essential for every household.

What Is RSV and Why Does It Matter?

RSV is a virus that causes infections of the lungs and respiratory tract. It spreads easily through droplets when an infected person coughs or sneezes, or by touching surfaces contaminated with the virus. While most healthy adults and older children experience mild cold-like symptoms, RSV can cause severe illness in:

• Infants, especially those under 6 months old

• Premature babies

• Children with chronic lung or heart conditions

• Older adults with weakened immune systems

  
  

During RSV season, hospitals often see a rise in cases of bronchiolitis and pneumonia caused by this virus. Understanding the risks helps families prepare and respond appropriately.

When Does RSV Season Occur?

RSV season typically begins in the fall and peaks in the winter months, lasting through early spring. The exact timing can vary by region and year, but in many parts of the United States, RSV activity starts around October or November and continues until March or April.

The virus thrives in colder months because people spend more time indoors in close contact, which helps it spread. Schools and daycare centers also become hotspots for transmission during this time.

Signs and Symptoms to Watch For

Recognizing RSV symptoms early can make a difference in how quickly your child receives care. Common symptoms include:

• Runny nose

• Coughing and sneezing

• Fever

• Decreased appetite

• Wheezing or difficulty breathing in severe cases

  
  

In infants, watch for signs such as:

• Rapid or troubled breathing

• Bluish color around lips or fingernails

• Unusual fussiness or lethargy

• Poor feeding

  
  

If you notice these symptoms, especially trouble breathing or dehydration, seek medical attention promptly.

How RSV Spreads and How to Prevent It

RSV spreads through close contact with infected individuals or contaminated surfaces. The virus can survive on hard surfaces for several hours, making hand hygiene and cleaning crucial.

Here are practical steps families can take to reduce the risk:

• Wash hands frequently with soap and water for at least 20 seconds

• Avoid close contact with sick individuals

• Clean and disinfect toys, doorknobs, and surfaces regularly

• Cover coughs and sneezes with a tissue or elbow

• Avoid sharing cups, utensils, or towels

• Keep infants away from crowded places during peak RSV season if possible

  
  

For high-risk infants, doctors may recommend a preventive medication called palivizumab during RSV season. This is given as monthly injections and helps reduce the severity of infection.

Managing RSV at Home

Most RSV infections can be managed at home with supportive care. Here are some tips to help your child feel better:

• Keep them hydrated with breast milk, formula, or fluids

• Use a cool-mist humidifier to ease breathing

• Clear nasal congestion with saline drops and a bulb syringe

• Monitor temperature and use fever reducers as advised by your healthcare provider

• Ensure plenty of rest

  
  

Avoid using over-the-counter cough and cold medicines in young children unless directed by a doctor.

When to Seek Medical Help

While many RSV cases are mild, some require medical attention. Contact your healthcare provider if your child:

• Has difficulty breathing or rapid breathing

• Shows signs of dehydration (dry mouth, no tears when crying, fewer wet diapers)

• Has a high fever lasting more than a few days

• Appears unusually sleepy or unresponsive

• Develops bluish skin or lips

  
  

Early intervention can prevent complications and improve outcomes.

Protecting Your Family Beyond RSV Season

Good hygiene habits and healthy lifestyle choices help protect your family year-round. Encourage regular handwashing, avoid close contact with sick people, and keep vaccinations up to date, including the flu vaccine, which can reduce the risk of respiratory infections.

If you have a newborn or a family member with health concerns, discuss RSV prevention strategies with your pediatrician or healthcare provider.
