Respiratory syncytial virus (RSV) causes cold-like symptoms in most adults. But adults over 65 and those with conditions affecting their lungs, heart or immune system face an increased risk of complications like pneumonia. Each year, RSV leads to thousands of hospitalizations and deaths. Adults over age 60 can get vaccinated to reduce this risk.

Respiratory syncytial virus (RSV) is a virus that can lead to an upper respiratory infection in adults of all ages. Most people think of RSV as a virus that affects babies and kids. RSV spreads easily among children and can lead to severe symptoms, especially in infants. But RSV affects adults, too, and can sometimes be life-threatening.

Usually, RSV causes mild illness in adults. Most adults who catch RSV just think they have a common cold because the symptoms are the same. However, RSV can also make you very sick. It can cause lower respiratory infections like pneumonia and bronchitis in older adults or adults with other health problems.
Lower respiratory infections like these can be harder to fight off if you’re 65 or older. In part, that’s because your immune system gets weaker as you age. Some underlying medical conditions, especially those involving your heart or lungs, also make you more vulnerable to complications from RSV.
The U.S. Food and Drug Administration (FDA) recently approved RSV vaccines for adults over age 60. Getting vaccinated when you’re eligible can help you avoid serious illness. Plus, there’s a lot you can do in your daily life to stay healthy. From handwashing to avoiding people who are sick, simple steps can go a long way toward helping you avoid seasonal respiratory viruses like RSV.
Because an RSV infection usually feels like a cold, many adults don’t get tested or find out they have it. So, it’s hard to know exactly how common it is.
We do know that RSV causes at least 60,000 to 160,000 hospitalizations per year among adults age 65 or older in the U.S. Some need care in the intensive care unit (ICU). RSV is responsible for about 6,000 to 10,000 deaths among older adults each year.

Adults usually have typical cold symptoms, including:
When RSV leads to complications like pneumonia or bronchitis, additional symptoms can develop. You might have one or more of the following:
A virus causes an RSV infection. RSV stands for respiratory syncytial virus, which is the specific virus that makes you sick.
Yes, RSV is contagious. It’s a viral infection that spreads through respiratory droplets. You can catch RSV when someone who has the infection coughs or sneezes and those droplets land in your eyes, nose or mouth. You can also catch it from touching droplets or a contaminated object (like a table or doorknob) and then touching your face.
Possible complications of RSV in adults include:
You have an increased risk of complications if you:
Among adults with compromised immune systems, the risk of severe illness appears to be the highest among people who:
Healthcare providers diagnose RSV by talking to you about your symptoms and doing a physical exam. They may also do a swab test to check your mucus for the presence of RSV.
There are antiviral treatments for RSV but they’re generally only used in adults with immune problems. Healthcare providers recommend you manage your symptoms and stay comfortable with the treatments you’d use for a cold. These include:
Continue taking prescription medications for asthma, COPD or other conditions as your provider recommends.
If you develop complications, you may need care at a hospital. A healthcare provider will tailor care to your needs. In general, they may:

No. Antibiotics don’t work against RSV because RSV is viral, not bacterial. Antibiotics only treat bacterial infections.
Your healthcare provider may prescribe antibiotics if testing shows you have bacterial pneumonia or another type of bacterial infection in addition to the RSV.
Viruses like RSV are often hard to avoid. But there’s still a lot you can do to lower your risk of getting sick or developing complications:

Symptoms of RSV usually clear up within a week or two. You may be sick longer if RSV leads to complications like pneumonia.
After you’re exposed to RSV, it takes about four to six days for symptoms to show up. They may appear in stages rather than all at the same time. Once you have symptoms, you can expect them to last two to eight days. Most people fully recover in one to two weeks unless complications develop.
In most cases, no. But you may have long-term effects if you’re living with one or more of the following conditions:
RSV can make these existing conditions worse. You may have more severe symptoms or require additional care. If you have any of these conditions, talk to your healthcare provider about how viral infections might affect you and how to protect yourself.
You might manage RSV just fine with at-home care. But you should call a healthcare provider if you develop a really bad cold and at least one of the following applies to you:
Your provider will tell you if you should come in to see them. They’ll also explain signs and symptoms of a severe infection and when you should seek emergency care.

A note from Cleveland Clinic
There’s never a convenient time to get sick. But most adults are used to getting a cold or two per year and going about business as usual. RSV often feels just like that — a blip on the radar that passes quickly. But if you’re living with certain chronic conditions, or even just as you get older, RSV and other common respiratory viruses can become more dangerous.
That’s why it’s important to learn if you’re at risk for complications and take measures to protect yourself from infection. Talk to your healthcare provider to learn more about how RSV might affect you and ways to stay healthy.
