Respiratory Virus Surveillance -- United States, 1983
Since September 1983, CDC has collected reports of noninfluenza
respiratory virus isolations from certain state and university
virology laboratories. The viruses reported include respiratory
syncytical virus (RSV), parainfluenza virus types 1-4, and
rhinoviruses. Reports received through December 19 show: (1)
increasing numbers of RSV isolates beginning in November in the
South
Atlantic, West South Central, and Mountain regions and appearance
of a
few RSV isolates in the New England, East South Central, and
Pacific
regions during this same time period; (2) parainfluenza type 1
isolates occurring in the New England, Mid-Atlantic, East North
Central, West North Central, South Atlantic, West South Central,
and
Mountain regions, with peak numbers of isolates in October. The
largest numbers of isolates were reported from the Mid-Atlantic and
Mountain regions; 42/310 and 40/147, respectively, of the
respiratory
specimens tested were positive for parainfluenza type 1. Smaller
numbers of parainfluenza types 2 and 3 and rhinovirus isolates were
reported during this time period.

Editorial Note
Editorial Note: The purpose of this respiratory surveillance
program
is to identify the timing and locations of outbreaks of
noninfluenza
respiratory viruses in the United States. Initially, the program
will
focus on RSV and the parainfluenza viruses. RSV causes yearly
outbreaks sometime between late fall and early spring;
parainfluenza
types 1 and 2 cause periodic outbreaks, often every other year in
the
fall; and parainfluenza type 3 is likely to be isolated throughout
the
year, with periodic outbreaks also occurring.
