Most adults with RSV (respiratory syncytial virus) recover at home within one to two weeks using the same basic strategies you’d use for a bad cold: rest, fluids, and over-the-counter symptom relief. There’s no antiviral medication routinely prescribed for otherwise healthy adults with RSV, so treatment focuses on keeping yourself comfortable while your immune system clears the virus.
That said, RSV can hit harder than a typical cold, especially if you have a chronic health condition. Knowing how to manage symptoms at home, when to call a doctor, and who’s at higher risk can make a real difference in how smoothly you recover.
Managing Symptoms at Home
RSV in adults usually looks like an upper respiratory infection: congestion, sore throat, mild headache, fatigue, and sometimes a low-grade fever. The goal of home care is to ease those symptoms while your body fights the virus.
Over-the-counter acetaminophen can help bring down a fever and relieve throat pain. Saline nasal drops are a simple, effective way to loosen congestion without adding more medication. If your nose is significantly blocked, a short course of a decongestant spray may help, but saline alone works well for most people.
Staying hydrated matters more than usual during a respiratory infection. Warm liquids like broth or soup can help thin out thickened mucus in your airways, making it easier to clear. Keep water within reach throughout the day. A general target is around 9 cups of fluid daily for women and 12 cups for men, though you may need more if you’re running a fever or sweating.
Humid air can soothe irritated airways. A cool-mist humidifier in your bedroom helps, especially at night when congestion tends to worsen. Keep the room warm but not overheated. And stay away from cigarette smoke entirely, including secondhand exposure, because it aggravates respiratory symptoms and can slow your recovery.
How Long Recovery Takes
Most healthy adults feel noticeably better within a week, though a lingering cough and fatigue can stretch to two weeks or occasionally longer. You’re typically contagious for 3 to 8 days, and you may actually become contagious a day or two before symptoms appear. That means by the time you realize you’re sick, you’ve likely already been spreading the virus.
During recovery, avoid close contact with infants, elderly family members, and anyone with a weakened immune system. RSV spreads through respiratory droplets and can survive on surfaces like doorknobs and countertops, so frequent handwashing is one of the most effective things you can do to protect the people around you.
Who Faces Higher Risk
For most adults, RSV is an unpleasant but manageable illness. For certain groups, though, it can progress to pneumonia or bronchiolitis and require hospitalization. The CDC identifies several conditions that raise the stakes significantly:
- Chronic heart disease such as heart failure or coronary artery disease (not simply high blood pressure)
- Chronic lung conditions including COPD, emphysema, asthma, and interstitial lung disease
- Weakened immune systems, particularly in people who’ve had organ or stem cell transplants
- Severe obesity with a BMI of 40 or higher
- Diabetes with complications such as kidney disease, nerve damage, or insulin dependence
- Chronic liver disease like cirrhosis
- Neurologic conditions that weaken respiratory muscles or impair swallowing
- Residence in a nursing home or long-term care facility
If you fall into any of these categories and develop RSV symptoms, it’s worth contacting your doctor early rather than waiting to see how things progress. An infection that would be mild in a healthy 40-year-old can escalate quickly in someone with COPD or a suppressed immune system.
When Symptoms Need Medical Attention
Most adults won’t need to see a doctor for RSV. But certain warning signs mean the infection is becoming more serious. Seek care if you experience difficulty breathing, chest pain or pressure, trouble eating or drinking due to illness severity, sudden dizziness or confusion, or symptoms that were improving and then sharply worsen.
Worsening shortness of breath is the most important signal. RSV can move from the upper airways into the lungs, causing inflammation that makes it progressively harder to get enough oxygen. If you notice you’re breathing faster than normal, can’t finish a sentence without pausing for breath, or feel like you’re working harder to breathe even while resting, that warrants prompt evaluation.
Getting Diagnosed
RSV symptoms overlap heavily with the flu, COVID-19, and other respiratory viruses, so you can’t diagnose it based on how you feel alone. If your doctor wants to confirm RSV specifically, the most reliable method is a PCR-based nasal swab, which is highly sensitive at detecting the virus. Rapid antigen tests also exist and give faster results, but they’re less sensitive, meaning they can miss some infections. Many clinics now use combination tests that check for RSV, flu, and COVID simultaneously from a single swab.
For most healthy adults, identifying the exact virus doesn’t change the treatment plan. Testing becomes more important if you’re in a high-risk group, because a confirmed RSV diagnosis might prompt closer monitoring.
Treatment for Severe Cases
There are currently no antiviral drugs approved for routine RSV treatment in adults. In hospitalized patients with severely weakened immune systems, particularly those who’ve received stem cell or lung transplants, doctors sometimes use antiviral therapy on a case-by-case basis. But for the vast majority of adults, even those sick enough to be hospitalized, treatment remains supportive: supplemental oxygen if blood oxygen levels drop, IV fluids if dehydration is severe, and monitoring for secondary bacterial infections like pneumonia.
RSV Vaccines for Adults
Prevention is the most meaningful step you can take if you’re at risk for severe RSV. The CDC recommends a single dose of RSV vaccine for all adults 75 and older, and for adults 50 to 74 who have an increased risk of severe illness. Three vaccines are currently available for adults 50 and older, manufactured by GSK, Moderna, and Pfizer, with no preference among them.
The list of qualifying risk factors for the 50-to-74 age group is broad, covering conditions from chronic lung and heart disease to severe obesity, complicated diabetes, and moderate-to-severe immune suppression. If you think you qualify, your own statement about your health is considered sufficient evidence. Providers shouldn’t require medical documentation before giving the vaccine.
Unlike the flu shot, the RSV vaccine is currently recommended as a single lifetime dose rather than an annual one. If you’re in the eligible range and haven’t received it yet, any visit to your doctor or pharmacy is a reasonable time to ask.
