RSV Medical Abbreviation | RSV treatment

RSV stands for Respiratory Syncytial Virus, a common respiratory virus that infects the nose, throat, and lungs. While RSV often causes mild, cold-like symptoms, it can lead to serious illness—especially in infants, older adults, and those with weakened immune systems.

In short? RSV is more than just a seasonal sniffle—it’s a major cause of hospital visits for babies and vulnerable individuals.

What Is RSV?

RSV (Respiratory Syncytial Virus) is a highly contagious virus that spreads through droplets when an infected person coughs or sneezes, or by touching contaminated surfaces and then touching your face.

Most people recover in a week or two. But for some, especially young children, elderly adults, and people with chronic health conditions, RSV can cause severe respiratory infections like:

• Bronchiolitis (inflammation of the small airways in the lungs)

• Pneumonia

Symptoms of RSV

Symptoms typically appear 4 to 6 days after exposure and can range from mild to severe:

• Coughing and sneezing

• Runny nose

• Fever

• Wheezing

• Shortness of breath

• Fatigue

• Decreased appetite

• Irritability in infants

In babies, signs may be subtle—such as reduced activity, poor feeding, or breathing trouble—so it’s crucial to watch carefully.

When Is RSV Season?

RSV season typically occurs during fall and winter, with infections peaking between December and January in many parts of the world.

Who’s Most at Risk?

Although RSV affects people of all ages, certain groups face a higher risk of complications:

• Infants, especially under 6 months

• Premature babies

• Children with heart or lung conditions

• Adults over 60

• People with weakened immune systems

In fact, RSV is the leading cause of hospitalisation for infants under 1 year old in the U.S. and a growing concern among older adults.

Prevention: Can RSV Be Avoided?

Yes—and here’s how:

• Vaccines:

  • One vaccine is available for adults aged 60+

  • Another protects newborns when given to pregnant people between 32 and 36 weeks gestation

• Monoclonal antibody treatments (like nirsevimab) are available for high-risk infants

• Frequent handwashing

• Avoiding close contact with sick individuals

• Disinfecting surfaces and toys

Treatment for RSV

There’s no cure for RSV, but supportive care can help ease symptoms:

• Fluids: Prevent dehydration, especially in children

• Fever reducers and pain relievers: Paracetamol (acetaminophen) or ibuprofen—never give aspirin to children

• Saline nasal drops and humidifiers: Help with congestion

• Hospitalisation: May be needed in severe cases, especially for infants struggling to breathe

Over-the-counter cough medications are not recommended for children under 4 years.

When to Seek Medical Help

Call a doctor immediately if a child or older adult:

• Is breathing rapidly or struggling to breathe

• Has bluish lips or fingernails

• Shows signs of dehydration (dry mouth, fewer wet nappies)

• Is unusually sleepy, lethargic, or irritable

In Summary

RSV (Respiratory Syncytial Virus) is a common but potentially serious illness, especially during the colder months. While it often feels like a cold, RSV can quickly turn dangerous for vulnerable groups. With new vaccines, monoclonal antibodies, and basic hygiene, it’s now more preventable than ever.
