Synagis is used to help prevent severe lung disease caused by a respiratory syncytial virus (RSV) in infants born prematurely and other children at high risk for severe lung disease from RSV.
HHSC bases RSV season dates on the county of residence. RSV appears earlier in some counties and remains active later in other counties. HHSC uses RSV statistics from prior years plus regular virology reports to determine the season's dates for each region and reserves the right to extend or end a season after subsequent review of RSV levels in each region. MCO medical directors can end the RSV season for their MCO by service area if they demonstrate the local virology has dropped below 10% positivity for two consecutive weeks.
