Current Trends Update: Respiratory Virus Surveillance -- United States, 1984

Reports of noninfluenza respiratory viruses identified by certain state and university laboratories and received by CDC through February 14, 1984, show that respiratory syncytial virus (RSV) has now been reported from all regions of the United States since December 1983 (Table 7). The rate of RSV identification remains high in most regions. The Mountain region reported the largest number of RSV identifications; 200 of 597 respiratory specimens tested during January and February were positive for RSV. No RSV isolates were reported in January or February in the East South Central region. With the addition of data from several university laboratories in the East North Central and West North Central regions, it appears that RSV was present in these regions in December, as it was in the rest of the United States.

Editorial Note

Editorial Note: The respiratory virus surveillance system demonstrates temporal and geographic patterns of noninfluenza respiratory viruses identified in the United States. These data indicate which viruses are circulating in a community but do not measure rates of illness or morbidity or mortality. Variability in the number of specimens tested, source and methods of specimen collection, and isolation and identification methods make it impossible to compare data among regions. Surveillance has demonstrated a nationwide occurrence of RSV this season, with onset at approximately the same time in all regions of the country. The reason for the absence of reported RSV in the East South Central region, despite its presence in all other regions in January and February, is unclear.
