Red flags & when to go in person for RSV (Suspected) - Triage

Audience: adult

Respiratory Syncytial Virus (RSV) is a common virus that causes respiratory infections. Adults with suspected RSV often experience symptoms like cough, runny nose, and mild fever. Most people recover at home with rest and fluids. However, RSV can sometimes cause more serious illness, especially in older adults or those with other health problems. This guide helps you understand when to seek in-person medical care. It also explains what telemedicine can and cannot do for suspected RSV. Knowing the warning signs, or red flags, can help you get timely care and avoid complications. Remember, this information is for education and triage only and is not a diagnosis. If you have severe symptoms or concerns, see a healthcare provider in person as soon as possible.

Red flags — go in person / ER

• Difficulty breathing or shortness of breath that worsens — seek emergency care immediately.
• Chest pain or tightness — go to an emergency room promptly.
• High fever not improving with medication or lasting more than a few days — see a healthcare provider in person.

What telemedicine can do

• Initial symptom assessment and triage for mild RSV symptoms.
• Providing advice on home care and symptom management.
• Determining if in-person evaluation is needed.
• Prescribing medications when appropriate and safe.

What telemedicine cannot do

• Performing physical examinations or lung function tests.
• Administering emergency treatments or oxygen therapy.
• Conducting laboratory tests to confirm RSV infection.
• Managing severe symptoms or complications requiring hospital care.

What is RSV and who is at risk?

Respiratory Syncytial Virus (RSV) is a virus that infects the lungs and breathing passages. It spreads through coughs, sneezes, or close contact. Adults usually have mild symptoms, but RSV can be more serious for older adults, people with lung or heart disease, or weakened immune systems. Knowing your risk helps you watch for signs that need medical attention.

Common symptoms of RSV in adults

Typical symptoms include:

Symptoms often start gradually and may last one to two weeks. Most people recover without special treatment.

Red flags: When to seek in-person care immediately

Certain signs mean you should get medical help right away:

If you notice any of these, go to an emergency room or urgent care immediately.

How telemedicine can help with suspected RSV

Telemedicine providers can:

Telemedicine is a good first step if symptoms are mild and you have no red flags.

Limitations of telemedicine for RSV

Telemedicine cannot:

If your condition worsens or you have red flags, you need to see a healthcare provider in person.

Preventing RSV spread and protecting yourself

To reduce your risk and protect others:

These steps help limit RSV transmission.

How to prepare for your tele-visit

• Have a list of your current symptoms and when they started.
• Know your medical history, including any chronic illnesses.
• Prepare to describe any medications or treatments you are using.
• Ensure you have a quiet, private space for the tele-visit.
• Have a thermometer and pulse oximeter (if available) ready to report readings.
• Be ready to discuss any changes in breathing or new symptoms.

After your tele-visit

• Follow the care advice and medication instructions given by the telemedicine provider.
• Monitor your symptoms closely, especially breathing and fever.
• Keep track of any new or worsening symptoms and seek in-person care if red flags appear.
• Rest and stay hydrated as recommended.
• Schedule follow-up appointments if advised.
• Practice infection control measures to protect others.

FAQs

Can adults get RSV more than once?

Yes, adults can get RSV multiple times because immunity after infection is not complete or long-lasting. Each infection is usually milder than the first.

How is RSV different from the common cold or flu?

RSV symptoms often overlap with colds and flu, including cough and fever. RSV mainly affects the lungs and can cause wheezing or breathing difficulties, especially in vulnerable adults.

Should I get tested for RSV?

Testing is not usually needed for mild cases. It may be done in hospitals or clinics to confirm diagnosis, especially for severe illness or during outbreaks.

How long is RSV contagious?

People with RSV can spread the virus for 3 to 8 days, but some, especially young children or those with weakened immune systems, may be contagious for longer.

Can I prevent RSV infection?

Good hygiene like handwashing, avoiding close contact with sick people, and cleaning surfaces helps reduce your risk. There is currently no widely available vaccine for RSV for adults.
