RSV season planning with a chronic condition
If you have a chronic condition — COPD, heart failure, asthma, diabetes, kidney disease, an autoimmune condition, or a compromised immune system — RSV season is something worth actively preparing for, not just reacting to. A few conversations with your care team and some practical habits can significantly reduce your risk of a severe RSV illness that disrupts your health and your treatment plan.
This guide walks through the components of an RSV season plan for higher-risk adults.
Step 1: Vaccination — get it before season starts
If you're 60 or older and haven't received an RSV vaccine, it's the highest-impact step you can take. Two vaccines are FDA-approved for adults 60+: Abrysvo (Pfizer) and mRESVIA (Moderna). Your doctor or pharmacist can help you choose and administer it.
The ideal timing is August through October, before RSV season starts in most of the country. Protection takes 2–4 weeks to build after the shot, so vaccinating before peak season matters. If you have an underlying condition that affects vaccine response (transplant, active chemotherapy, high-dose immunosuppression), your timing may be different — ask your specialist.
Alongside RSV, make sure you're also current on flu and COVID vaccines. These three respiratory viruses overlap in season and all pose elevated risk with chronic conditions.
Step 2: Know your personal escalation threshold
One of the most useful things you can do is establish — in advance, with your doctor — a clear answer to: "When do I call you vs. go to the ER?"
This varies by condition:
- COPD: Call if you're using your rescue inhaler more than twice your normal frequency, or if your breathing is noticeably worse than baseline. Go to the ER if you can't complete a sentence, your lips are blue, or your SpO₂ drops below 88–90%.
- Heart failure: Call if you develop new shortness of breath, sudden weight gain of 2+ lbs overnight, or swelling in your legs with a respiratory illness. Go to the ER if breathing becomes severe or you have chest pain.
- Asthma: Call if your peak flow drops below your personal yellow zone or your rescue inhaler isn't providing 4+ hours of relief. Go to the ER if you can't speak in full sentences or your rescue inhaler isn't working.
- Immunocompromised: Call your specialist at the first sign of any respiratory symptoms. Don't wait to see if it's "just a cold."
Write your thresholds down, share them with a family member or caregiver, and put your doctor's after-hours number somewhere accessible.
A useful exercise: At your next appointment before RSV season, ask your doctor: "If I get a respiratory illness this winter, what signs should make me call you immediately? What should make me go to the ER?" Get a specific answer and document it.
Step 3: Have a home monitoring baseline
Knowing your baseline vital signs makes it much easier to detect meaningful change when you're sick. Before RSV season, record your:
- Resting SpO₂ (oxygen saturation on a pulse oximeter). Healthy adults are typically 97–100%. Your baseline may differ — know your number.
- Resting heart rate and blood pressure if you have cardiovascular disease
- Peak flow reading if you have asthma (best of three in the morning)
- Baseline weight if you have heart failure (daily weight monitoring is already standard for many heart failure patients)
A pulse oximeter is inexpensive and useful for anyone with a respiratory or cardiac condition going into RSV season.
Step 4: Reduce exposure during peak months
RSV season runs roughly October through March in most of the US. During this window:
- Wash hands frequently — especially after being in public spaces and before touching your face
- Avoid close contact with people who have obvious cold symptoms
- Consider wearing a high-quality mask (N95 or KN95) in crowded indoor spaces, healthcare waiting rooms, or during peak RSV weeks in your area
- Ask family members — especially grandchildren in daycare or school — to wash hands before close contact during RSV season
- Wipe down frequently touched surfaces during periods of high household illness
You don't need to live in a bubble. These habits, combined with vaccination, meaningfully reduce your RSV risk without requiring you to give up normal life.
Step 5: Know what RSV season looks like in your area
RSV season varies by region — the Southeast typically sees activity start in September, while the Pacific Northwest peaks later, in December or January. The homepage shows current RSV activity in your state based on CDC hospital admissions data. Checking it at the start of season (and periodically through winter) gives you a real-time signal about when to be most careful.
Step 6: Have a plan if you do get sick
Even with vaccination and precautions, you may get RSV. Having a plan reduces the chaos:
- Know where to get RSV testing if symptoms start — some urgent care centers and all emergency rooms can test
- Have your specialist's after-hours or nurse line number saved
- Know your nearest emergency room and, if relevant, which hospital your specialist is affiliated with
- Have a family member or trusted person who knows your medical history and can accompany you if you need emergency care
- Keep any rescue medications (inhalers, diuretics, etc.) filled and accessible
