States with Lab-confirmed
Enterovirus D68
From mid-August to September 22, 2014, a total of 175 people from
27 states were confirmed to have respiratory illness caused by EV-D68. The 27
states are Alabama, Arkansas, California, Colorado, Connecticut, District of Columbia,
Georgia, Illinois, Indiana, Iowa, Kansas, Kentucky, Louisiana, Michigan,
Minnesota, Mississippi, Missouri, Montana, Nebraska, New Jersey, New York,
North Dakota, Oklahoma, Pennsylvania, Virginia, Washington, and West Virginia.
The cases of EV-D68 infection were confirmed by the CDC or state public health
laboratories that notified CDC.
In the upcoming weeks, more states will have confirmed cases of
EV-D68 infection.
· The primary reason for increases in cases is that several states
are investigating clusters of people with severe respiratory illness, and
specimens are still being tested for EV-D68. It can take a while to test
specimens and obtain lab results. That’s because the testing is complex and
slower, and can only be done by CDC and a small number of state public health
laboratories. As the backlog of specimens is processed, the number of states
and confirmed cases will likely increase. These increases will not necessarily
reflect changes in real time, or mean that the situation is getting worse.
· Some of the increase will be from new EV-D68 infections since
people are more likely to get infected with enteroviruses in the summer and
fall. We are currently in the middle of the enterovirus season.
As investigations progress, we will have a better understanding of
the trends for EV-D68 infections.
