Washington, D.C. – The Centers for Disease Control and Prevention (CDC) has issued an urgent health alert as respiratory syncytial virus (RSV) cases surge among children, particularly infants and toddlers, leading to a sharp increase in hospitalizations across multiple U.S. states. Health officials report emergency room visits for RSV in young children have jumped by up to 35% in recent weeks, coinciding with the peak RSV season. The CDC is now strongly recommending vaccinations and preventive measures to protect vulnerable kids amid this alarming uptick.

RSV, a common respiratory virus that typically causes mild cold-like symptoms in older children and adults, can lead to severe illness in babies under 6 months and toddlers with underlying conditions. This season’s surge has overwhelmed pediatric units in key states, prompting the CDC to track data closely through its Respiratory Virus Hospitalization Surveillance Network (RSV-NET).
Infant Hospitalizations Double in Key Metrics, CDC Data Reveals
The CDC’s latest surveillance data paints a stark picture: RSV-associated hospitalizations among children under 2 years old have risen 25-35% compared to the same period last season. In the week ending October 28, over 1,500 RSV-related hospital admissions were recorded nationwide for this age group, a 28% surge from the prior week. Infants younger than 6 months are bearing the brunt, accounting for nearly 45% of cases, according to preliminary figures released Friday.
“We are seeing RSV activity ramp up earlier and more intensely than in recent years,” said Dr. Fiona Havers, a CDC medical officer specializing in respiratory viruses. “This surge in children underscores the need for proactive protection, especially with new tools like monoclonal antibodies available.”
Historical context adds urgency: Pre-pandemic RSV seasons typically peaked in December, but this year’s early onset mirrors patterns seen in 2021 when COVID-19 restrictions delayed exposure and lowered population immunity. The CDC notes that wastewater surveillance shows RSV viral loads climbing in 15 states, signaling broader spread ahead.
- Key Stats: RSV test positivity rates in children hit 12.5% nationally, up from 8% last month.
- Hospitalization rates: 2.5 per 1,000 children under 2, highest since 2019.
- ICU admissions for RSV in kids: Up 40% in the past two weeks.
These numbers are drawn from over 80 hospitals in RSV-NET, providing a representative snapshot of the crisis unfolding in pediatric care.
California, Texas, and New York ERs Overwhelmed by RSV Wave
Frontline health departments in California, Texas, and New York have confirmed the RSV surge, with emergency departments reporting record pediatric visits. In California, the Department of Public Health logged a 32% increase in RSV-positive tests among children under 5, straining hospitals in Los Angeles and San Francisco. “Our pediatric ICUs are at capacity,” warned Dr. Tomás Aragón, California’s health officer. “Parents should know the signs and act fast.”
Texas sees similar chaos: The Texas Department of State Health Services reported over 2,800 RSV cases in children last week alone, a 50% jump from early October. Dallas and Houston hospitals have activated surge protocols, diverting non-critical cases. New York State’s dashboard shows RSV hospitalizations in kids under 2 surging 29%, with New York City pediatric ERs handling 15% more RSV patients daily.
| State | RSV Hospitalizations (Children <2, Last Week) | % Increase YoY |
|---|---|---|
| California | 450+ | 32% |
| Texas | 620+ | 50% |
| New York | 380+ | 29% |
These states represent over 25% of U.S. pediatric hospitalizations, amplifying national concerns. Local officials attribute the spike to school reopenings, holiday gatherings looming, and waning maternal antibodies in newborns.
CDC Pushes RSV Vaccinations and Nirsevimab Shots for Children
In response to the surge, the CDC is ramping up calls for vaccination and immunoprophylaxis. For infants, the agency recommends nirsevimab (Beyfortus), a long-acting monoclonal antibody that provides RSV protection for up to 6 months. Approved last year, it’s now covered by most insurance and recommended for all infants entering their first RSV season, especially those born during or just after summer.
Pregnant women at 32-36 weeks gestation can receive the Abrysvo vaccine, passing antibodies to newborns. “Vaccination is our best defense,” emphasized CDC Director Dr. Mandy Cohen in a virtual briefing. “We’ve seen up to 80% reduction in severe RSV disease with these interventions.”
Supply has improved since last season’s shortages, but demand is outpacing in high-burden areas. The CDC advises pediatricians to prioritize high-risk children: preterm infants, those with congenital heart disease, or chronic lung conditions.
- Maternal Vaccination: 32-36 weeks pregnancy; reduces infant hospitalization by 57%.
- Nirsevimab for Infants: Single dose at birth or before season; 70-80% effective against severe disease.
- High-Risk Kids 8-19 Months: Second dose if needed.
Over 500,000 doses of nirsevimab have been administered this season, but experts warn of potential gaps if uptake doesn’t accelerate.
Why This RSV Surge is Hitting Children Harder Than Expected
Experts point to a “perfect storm” fueling the RSV surge in children. Post-COVID immunity debt—fewer exposures during lockdowns—has left young kids susceptible. Climate factors, like warmer falls delaying indoor crowding, may have shifted peaks earlier. Additionally, concurrent flu and COVID circulation complicates diagnosis and treatment.
Dr. Alicia Fry, CDC RSV lead, noted in an interview: “Children born during the pandemic missed natural priming exposures, so this season’s virus is hitting them like a freight train.” Genomic sequencing shows the dominant strain is RSVA, known for severity in infants.
Comparisons to past seasons: 2022 saw a similar early surge, with 58,000 hospitalizations and 500 child deaths nationwide. This year could surpass that if unchecked, per modeling from the University of Utah.
Social media buzz from parents sharing stories of overnight ER dashes has amplified awareness, but also spread misinformation on vaccinations. Pediatric groups like the American Academy of Pediatrics are countering with fact sheets.
Protecting Kids: Spotting RSV Symptoms and Prevention Strategies
As RSV sweeps through communities, parents must stay vigilant. Common symptoms in children include runny nose, cough, sneezing, fever, and wheezing. Severe signs—rapid breathing, bluish lips, or lethargy—demand immediate ER visits.
Prevention remains key beyond vaccination:
- Handwashing with soap for 20 seconds.
- Avoiding sick contacts, especially for infants.
- Cleaning high-touch surfaces.
- Breastfeeding to boost antibodies.
- No smoking around kids.
“Empower parents with knowledge,” says Dr. Samira Shah, a California pediatrician. “Early antiviral like palivizumab for select high-risk cases can prevent hospitalization.”
Looking ahead, the CDC anticipates peak RSV activity through January, overlapping with flu season. Wastewater trends and ED syndromic surveillance will guide weekly updates. States are expanding testing and telehealth for mild cases to ease burdens. With vaccination rates climbing—now at 45% for eligible pregnant women—officials hope to blunt the wave. Public campaigns, including PSAs in high-impact states, aim to close immunity gaps before holidays peak transmission.
Families are urged to consult pediatricians promptly for vaccination eligibility. As winter deepens, the focus sharpens on shielding the youngest from RSV’s grip.
