AbstractA prospective study among adults hospitalized for polymerase chain reaction-confirmed respiratory syncytial virus infections (n = 123) showed frequent occurrence of lower respiratory-tract complications causing respiratory insufficiency (52.8%), requirement for assisted ventilation (16.3%), and intensive care unit admission/death (12.2%). High viral RNA concentration was detected at time of hospitalization, including in patients who presented later than 2 days of illness (day 1-2, 7.29 ± 1.47; day 3-4, 7.28 ± 1.41; day 5-8, 6.66 ± 1.87 log10 copies/mL). RNA concentration was independently associated with risk of complications and respiratory insufficiency (adjusted odds ratio 1.40 per log10 copies/mL increase, 95% confidence interval, 1.03-1.90; P =. 034). Our data indicate the need and provide a basis for clinical research on antiviral therapy in this population.
