RSV sends millions of children under 5 to the hospital worldwide each year, and in the US the infant hospitalization rate is as high as 1 in 38 during the first season. Even when infants look like they are “just” getting over a cold, RSV can lead to wheezing in 20 to 30 percent and trigger apnea in 10 percent of hospitalized preterm babies. Let’s break down what the latest RSV statistics reveal across ages, severity, outcomes, and costs.

Key Takeaways

RSV leads to 2-3 million hospitalizations worldwide in children under 5 yearly
In US infants under 1 year, RSV hospitalization rate is 1 in 38 during first season
RSV bronchiolitis requires mechanical ventilation in 2-5% of hospitalized infants
RSV diagnosis sensitivity of rapid antigen test is 80-90% in children
PCR testing detects RSV with 95-100% sensitivity in nasopharyngeal swabs
RSV IgM serology has low specificity (50-70%) for acute infection
In the United States, RSV accounts for an estimated 58,000-80,000 hospitalizations among children younger than 5 years each year
Globally, RSV is responsible for approximately 33 million lower respiratory tract infections in children under 5 years annually
In the US, nearly all children are infected with RSV by their second birthday
Palivizumab prophylaxis efficacy 39-82% against RSV hospitalization
Nirsevimab single-dose prevents 75-80% RSV hospitalizations in infants

Diagnostics Interpretation

The sobering reality of RSV diagnostics is that while PCR tests remain our reliable sentinel, our quest for the perfect rapid, point-of-care test is a bit like trying to catch a mischievous toddler with a butterfly net—often you'll get them, but they're usually three steps ahead and you're left with a lot of false reassurance and one very clear chest X-ray.
