Understanding RSV – Symptoms, Prevention, and Care
Respiratory Syncytial Virus (RSV) is one of the most common causes of respiratory illness in young children and a serious threat for infants under 6 months and adults over 65. At Monarch Medicine, our pediatric urgent care team evaluates and treats RSV in patients of all ages—same day, no appointment needed.
In our Carmel clinic, we see RSV cases surge each fall and winter. Dr. Clay’s guidance is consistent: don’t wait on RSV, especially in young infants. Early evaluation can prevent a manageable illness from becoming a medical emergency.
RSV Symptoms and Prevention
RSV is a highly contagious respiratory virus that infects the lungs and airways. According to the CDC, nearly all children are infected with RSV at least once by age 2. In healthy adults and older children, RSV typically causes mild cold-like symptoms. In high-risk populations, it can rapidly progress to bronchiolitis or pneumonia requiring hospitalization.
RSV season in Indiana generally runs from October through March, overlapping with flu and COVID-19 season—which is exactly why accurate testing matters. Symptoms look nearly identical across all three illnesses.
RSV Symptoms: What to Watch For
Symptoms typically appear 4–6 days after exposure. The table below shows how RSV presents differently across age groups—something Dr. Clay uses in practice during initial evaluation:
| Patient Group | Typical Symptoms | Severity Risk |
|---|---|---|
| Infants under 6 months | Irritability, decreased feeding, rapid/labored breathing, apnea (pauses in breathing) | HIGH — seek care immediately |
| Young children (6 mo–5 yr) | Runny nose, cough, fever, wheezing, decreased appetite | MODERATE–HIGH |
| Older children & healthy adults | Cold-like symptoms: congestion, mild cough, low-grade fever, fatigue | LOW–MODERATE |
| Adults 65+ or immunocompromised | Worsening cough, shortness of breath, fatigue, possible pneumonia | HIGH |
Per the CDC, RSV is the leading cause of infant hospitalization in the United States, responsible for approximately 58,000–80,000 hospitalizations annually in children under 5.
Who Is Most at Risk for Severe RSV?
While RSV can affect anyone, the following groups face the highest risk of serious complications including bronchiolitis and pneumonia:
- Infants under 6 months, especially premature babies
- Children under 2 with congenital heart or chronic lung disease
- Adults 65 and older
- Individuals with weakened immune systems (chemotherapy, organ transplant, HIV)
- Adults with COPD, asthma, or congestive heart failure
The American Academy of Pediatrics recommends that high-risk infants be considered for preventive monoclonal antibody therapy (nirsevimab/Beyfortus). Discuss eligibility with your pediatrician or bring it up at your next Monarch Medicine visit.
How RSV Spreads
RSV is highly contagious. It spreads through direct contact with respiratory droplets from coughing or sneezing, touching contaminated surfaces and then touching your face, and close contact with infected individuals. The virus can survive on hard surfaces for several hours, making hand hygiene and surface disinfection essential during RSV season.
In our experience treating families in Carmel, RSV frequently passes rapidly through households once one child is infected. If one child tests positive, closely monitor all siblings—especially any infants in the home.
When to Seek Urgent Care for RSV
Visit Monarch Medicine promptly if you or your child experience:
- Rapid or labored breathing, or nostrils flaring with each breath
- Wheezing or a high-pitched sound while breathing
- Fever lasting more than 3 days or above 104°F
- Signs of dehydration: no tears when crying, dry mouth, no wet diapers for 6+ hours
- Decreased activity, lethargy, or unusual irritability in infants
- Symptoms that improve then suddenly worsen
Go directly to the ER or call 911 if: Your infant has pauses in breathing (apnea), lips or fingernails appear bluish, or your child cannot be roused. These are emergencies—do not drive to urgent care.
How We Diagnose and Treat RSV at Monarch Medicine
Our diagnostic testing includes rapid RSV testing with same-day results. Because RSV, flu, and COVID-19 present so similarly, we often run a full respiratory panel in a single visit—confirming exactly what you’re dealing with so treatment is targeted, not guesswork.
There is no specific antiviral medication for RSV, but our illness treatment focuses on symptom management and complication prevention:
- Nebulizer treatments — For wheezing and airway inflammation, delivered via our on-site treatment suite
- IV hydration — For patients who can’t maintain adequate fluid intake due to rapid breathing or vomiting
- Fever and symptom management — Age-appropriate dosing guidance and prescription support when needed
- Chest X-ray — If pneumonia is suspected, our walk-in X-ray provides same-day imaging with no referral needed
Based on our experience treating pediatric patients in Carmel, the families who fare best are those who come in early—before dehydration or breathing difficulty sets in. Dr. Clay’s rule of thumb: if your infant seems to be working hard to breathe, don’t wait until morning.
RSV Prevention: What You Can Do
There is no widely available RSV vaccine for children under 8 months, though the CDC now recommends RSV vaccination for adults 60 and older and for pregnant women (to protect newborns). Preventive monoclonal antibody therapy is available for eligible high-risk infants.
Beyond medical prevention, practical steps make a meaningful difference: wash hands frequently with soap and water for at least 20 seconds, disinfect high-touch surfaces including toys, tables, and doorknobs, avoid close contact with anyone showing cold-like symptoms, and cover coughs and sneezes with your elbow. During peak RSV season, Dr. Clay recommends limiting newborn exposure to large group gatherings.
We offer RSV vaccination for eligible adults at Monarch Medicine—walk in during any open hours.

Frequently Asked Questions About RSV
RSV, colds, and flu share overlapping symptoms including runny nose, cough, and fever. The key differences: flu hits suddenly with high fever and body aches; RSV more commonly causes wheezing and lower respiratory symptoms; a common cold rarely causes fever or significant breathing difficulty. The only reliable way to differentiate them is rapid testing, which we offer on-site.
Yes. Adults can and do get RSV, though it typically presents as a mild cold. Adults 65 and older or those with COPD, heart disease, or compromised immune systems are at significantly higher risk for severe illness. The CDC now recommends RSV vaccination for adults 60 and older—ask about eligibility at your next visit.
There is no specific antiviral medication for RSV in otherwise healthy patients. Treatment focuses on symptom management: controlling fever, preventing dehydration with adequate fluids (or IV hydration when needed), and relieving airway inflammation with nebulizer treatments. In severe cases, hospitalization may be required for oxygen support and close monitoring.
Come to Monarch Medicine for: rapid breathing, wheezing, mild to moderate dehydration, fever lasting more than 3 days, or symptoms that worsen after initial improvement. Go directly to the ER or call 911 for: pauses in breathing (apnea), bluish lips or fingernails, severe lethargy, or inability to rouse your infant. These are emergencies that require hospital-level care immediately.
In healthy older children and adults, RSV typically resolves within 1–2 weeks. In infants and high-risk individuals, symptoms can persist longer and may worsen around days 3–5 before improving. If symptoms are not improving by day 5–7, or if they worsen at any point, come in for evaluation.
Yes. We offer rapid RSV testing with same-day results as part of our on-site diagnostic testing. We can also run flu A/B, COVID-19, strep, and mono in the same visit—so you leave with a confirmed diagnosis, not a best guess.
