ENTEROVIRUS D68 (EV-D68) NOW IN 40 STATES: TEXAS AND DELAWARE LATEST
From mid-August to September 29, 2014, CDC or state public health laboratories have confirmed a total of 443 people from 40 states and the District of Columbia with respiratory illness caused by EV-D68. The 40 states are (Newly added states are listed in BOLD type):
District of Columbia (Washington, DC)
This indicates that at least one case has been detected in each state listed but does not indicate how widespread infections are in each state.
CDC is prioritizing testing of specimens from children with severe respiratory illness. Of the specimens tested by CDC lab, about half have tested positive for EV-D68. About one third have tested positive for an enterovirus or rhinovirus other than EV-D68.
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.
