Figure 1. RSV (colored transmission electron micrograph).

Although RSV is known to cause LRTIs and related symptoms, other manifestations of infection can occur. For example, symptoms associated with upper respiratory tract infections, such as rhinorrhea and congestion, occur and then progress to involve the lower respiratory tract, with such symptoms as cough, increased work of breathing, rales, and diffuse wheezing. In addition, sepsis-like presentation or apneic episodes (the highest incidence occurring in infants < 1 month of age and premature infants) is typical, as is low-grade fever (although temperatures do rise in about 20% of patients with advanced disease). Diarrhea and emesis are not linked with RSV.
