RSV vs Common Cold: What Parents Need to Know
Both RSV and the common cold are viruses that spread through tiny water droplets when sneezing, coughing or even a hug.
They often show similar symptoms: stuffy nose, cough, and tired eyes. Although there are many similarities between RSV and the common cold there are a few strong differences. Infants and those older than 60 have a greater chance in contracting RSV while anyone can catch a common cold. And unlike a cold that can pop up any time, RSV has a season, kind of like the flu.
Here’s a quick side by side look at RSV compared to the common cold.
This information is meant to help families understand common symptoms, not replace medical advice. Always reach out to your child’s healthcare provider if you have concerns.
What causes RSV and the common cold?
RSV is caused by a single virus, while the common cold can be caused by more than 200 different viruses. Rhinovirus is the most common cause of colds.
How they spread
Both RSV and the common cold spread easily through coughing, sneezing, and close contact, which is why they move quickly through homes, classrooms, and daycare settings.
Common symptoms
RSV and colds often start with similar symptoms, including:
-
Cough
-
Congestion
-
Sneezing
-
Low energy or tiredness
With RSV, especially in younger children, symptoms may also include irritability or decreased activity.
Colds may also come with a runny nose and fussiness, but they are usually mild.
When symptoms may be more serious
RSV can sometimes cause more severe symptoms, particularly in infants and young children. Warning signs may include:
-
Difficulty breathing
-
Poor appetite or trouble drinking
-
Signs of dehydration
These symptoms should prompt a call to your child’s healthcare provider.
How long symptoms last
RSV symptoms typically begin 4–6 days after exposure and usually last 1–2 weeks.
Cold symptoms can also last up to two weeks but are usually mild and improve on their own.
Possible complications
Most colds resolve without complications. RSV, however, can sometimes lead to more serious illnesses such as:
-
Bronchitis
-
Pneumonia
-
Hospitalization in more severe cases
Seasonality
RSV tends to follow a seasonal pattern, showing up most often in the fall and winter months.
The common cold can happen any time of year.
