About RSV

Respiratory syncytial virus (RSV) is a common, highly contagious virus that can compromise the lungs and breathing passages. RSV can cause serious infections that can lead to hospitalizations and may be life-threatening.1,2

Who’s at high risk for severe RSV infection?

Premature infant

Premature infants4

Infant <6 months

Infants (≤ 6 months)4

Overlapping circles

Infants with certain underlying conditions5
e.g. Chronic lung disease | Congenital heart disease

67% of infants hospitalized for RSV were born at term with no underlying conditions.6*

*Based on RSV-associated hospitalizations among children aged < 2 years in the US from October 2014 through April 2015. Among 1,554 RSV-associated hospitalizations, 1,047 had no underlying conditions.6

Attributable costs for ARI attributed to RSV cases were substantially higher in the first 3 months. 8*

Raise RSV awareness in new parents and expecting parents to lessen the impact of RSV.

LRTI: lower respiratory tract infection; ARI: acute respiratory infection
