Epidemiologic Notes and Reports Update: Enterovirus
Surveillance -- United States, 1983
Through October 1983, the pattern of U.S. enterovirus isolates
reported to CDC remains similar to that reported through August
(1).
Coxsackievirus B5 remains the most commonly reported nonpolio
enterovirus isolate (347/1,415, 25% of the total), followed by
echovirus 11 (128 isolates), echovirus 24 (122), echovirus 30
(117),
and echovirus 20 (109) (Table 4). Sufficient isolates were
reported
from six regions to examine temporal patterns of isolation. For
four
of these, the number of enterovirus isolates (including
Coxsackievirus
B5), were increasing through August. In the Mid-Atlantic region,
the
peak occurred in July, while in the West South Central region,
enterovirus isolates peaked in June.
The distribution of ages and diagnoses reported for the
patients
from whom the isolates were taken has not changed substantially
from
the previous report.
