Respiratory Virus Surveillance -- United States, January 1985
Reports of noninfluenza respiratory viruses received at CDC
through January 18, 1985, indicate parainfluenza virus type 3 and
respiratory syncytial virus (RSV) are the most common noninfluenza
respiratory viruses isolated so far this respiratory virus season.
Parainfluenza type 3 isolates have been reported from all nine
regions
and in largest numbers from the New England (NE), Mid-Atlantic
(MA),
East North Central (ENC), West South Central (WSC), and Mountain
(MTN)
regions from September through November 1984. RSV began to be
isolated in increasing numbers in the MTN, NE, MA, and South
Atlantic
regions in December (Table 2). Parainfluenza types 1 and 2 have
been
reported from only three and two regions, respectively. In 1983,
these two types had occurred in all nine regions by November 30.

Editorial Note
Editorial Note: Reports of noninfluenza respiratory virus
isolations
are received from selected university and state virology
laboratories
in the United States. Reports will focus on RSV and parainfluenza
virus types 1, 2, and 3. Parainfluenza virus type 3 is often
isolated
year-round, with peaks occasionally occurring in the late winter or
spring (1,2). Outbreaks of RSV occur each year with peak
isolations
occurring sometime between December and March (3). RSV and
parainfluenza type 3 are the most common causes of lower
respiratory
tract illness among infants and young children. Parainfluenza
types 1
and 2 often cause outbreaks of croup in children in the fall of
alternating years (2).
