Cold vs. RSV in adults: Key differences and when to get tested

If you're feeling under the weather, it can be challenging to determine whether you're dealing with a simple cold or a more serious condition like RSV. Respiratory syncytial virus (RSV) is getting more attention lately, especially among older adults and people with weakened immune systems, because it can cause severe breathing problems or lead to hospitalization.

According to the National Foundation of Infectious Diseases (NFID), RSV often resembles a regular cold, with symptoms such as congestion, a sore throat, and fatigue; however, it can quickly progress to a deep cough, wheezing, or shortness of breath.¹ That's why early testing matters: catching RSV early can help you manage symptoms more effectively, protect those around you, and avoid spreading the virus to people at higher risk.

What is RSV, and why does it matter in adults?

According to the CDC, RSV, or respiratory syncytial virus, is a highly contagious virus that affects the lungs and breathing passages.³ While most healthy adults experience mild, cold-like symptoms, RSV can be much more serious for people over 60, those with chronic heart or lung issues, and anyone with a weakened immune system. In these groups, RSV can lead to complications like pneumonia or worsening of existing conditions. Cases among adults have been rising in recent years, prompting more awareness about how important it is to recognize and manage symptoms early, especially during peak respiratory illness season.

How RSV symptoms differ from a cold

At first glance, RSV can seem like an ordinary cold, but there are a few key differences to look out for. A typical cold might bring a runny nose, sore throat, mild fatigue, and a light cough, but RSV often causes deeper chest congestion, wheezing, and a persistent, more intense cough. You're also more likely to experience a noticeable fever, muscle aches, and even shortness of breath with RSV, especially if you're older or have underlying health issues. Unlike a cold that usually improves in a week, RSV symptoms often peak and worsen around days 3 to 5 and may last longer overall. Knowing these differences can help you decide when to rest, when to get tested, and when to seek medical care.

When to get tested for RSV

If you're feeling under the weather and are over 60, have a chronic condition, or are noticing your cough getting worse, it's a good idea to get tested for RSV, especially if you're also wheezing, having trouble breathing, or running a persistent fever.

Testing is especially important if you spend time caring for babies, older adults, or anyone with a weakened immune system, since RSV spreads easily and can hit vulnerable people harder.

The good news is that testing is simple and widely available at urgent care clinics, usually involving a quick nasal swab with results that can help guide your next steps.

What to do if you test positive

If you test positive for RSV, the most important thing you can do is rest, stay hydrated, and give your body time to recover. Over-the-counter medications like fever reducers or cough suppressants may help you feel more comfortable. Just be sure to follow your provider's recommendations.

Since RSV can be serious for older adults and those with weakened immune systems, it's important to isolate from anyone who's at high risk until you're fully recovered. If your symptoms start to worsen, especially if you have trouble breathing or feel extremely weak, reach out to a healthcare provider right away.

How to protect yourself and others from RSV

Protecting yourself and your loved ones from RSV doesn't have to be complicated; it starts with a few everyday habits:

• Try to avoid close contact with anyone who's sick, and wash your hands regularly after being in public places.
• During cold and flu season, wearing a mask in crowded indoor settings can add an extra layer of protection, especially if you're in a higher-risk group.
• If you start feeling under the weather, do your part by staying home and avoiding contact with others.

And don't forget: there's now an RSV vaccine available for certain adults, like those over 60 or with underlying health conditions.³ Ask your healthcare provider if it's right for you.
