Wellness Minister Lea Stevens says the scheduled program, which currently gets to about 35 percent of the 18,000 infants born in South Australia each full year, will be extended to reach all newborns by the finish of 2005. Ms Stevens says early screening may be the important to allowing children with a hearing insufficiency to correctly develop speech and language. First, a midwife bears out the initial hearing screening as part of regular postnatal testing immediately after birth. Then, after discharge from medical center, a Youth and Kid Wellness nurse follows up those infants assessed as needing another or third test. This may be at a clinic or on a genuine home visit. If a fourth evaluation is needed an audiologist then bears out extensive testing using special products.Surveillance and Ascertainment of Influenza Participants were instructed to get hold of their study site if they had any respiratory symptoms. In addition, participants had been contacted by a call center twice weekly or weekly until the end of disease surveillance . Three definitions of clinical illness were evaluated in the study. Respiratory illness was defined as the occurrence of one or more of the following: sneezing, nasal rhinorrhea or congestion, sore throat, cough, sputum production, wheezing, or difficulty breathing. This definition offered high sensitivity for the detection of situations of influenza and triggered key study procedures. A protocol-defined influenza-like illness provided increased specificity and clinical relevance beyond the respiratory illness description.
