The number of confirmed Enterovirus D68 (EV-D68) cases in the Canadian province of Alberta has risen to 111, as of Oct. 31, up from 93 cases two weeks ago.
Calgary zone still accounts for the majority of cases with 60 (54%). The other zones have reported confirmed cases as follows:Edmonton (19), Central (17), South (10) and North zone (5).
Confirmed EV-D68 cases have also been reported from British Columbia, Saskatchewan, Manitoba, Ontario, New Brunswick, Nova Scotia and Prince Edward Island.
In the United States, the CDC or state public health laboratories have confirmed a total of 1,105 people in 47 states and the District of Columbia with respiratory illness caused by EV-D68.
Of the more than 2,000 specimens tested by the CDC lab, about 40% have tested positive for EV-D68.
In addition, EV-D68 has been detected in specimens from nine patients who died and had samples submitted for testing.
CDC has obtained one complete genomic sequence and six nearly complete genomic sequences from viruses representing the three known strains of EV-D68 that are causing infection at this time.
Comparison of these sequences to sequences from previous years shows they are genetically related to strains of EV-D68 that were detected in previous years in the United States, Europe, and Asia.
