Trial overview
Official title: A prospective, epidemiological study to assess the disease burden of RSV associated, suspected LRTIs from 0 to 2 years and population attributable risk percent of RSV LRTI on the development of recurrent wheeze and asthma from 0 to 6 years
Trial description: The purpose of this study is to assess the incidence and associated healthcare utilization of RSV-associated, suspected LRTI in a general population of infants from birth up to 2 years of age, and also to assess the accuracy of a newly developed LRTI case definition and severity scale compared to two existing definitions. The study will also assess the population attributable risk percent of RSV LRTI on the development of wheeze and asthma from 0 to 6 years of age.
