Munro notes the distribution of previously resettled Central American minors in Missouri, Colorado and Illinois while conceding the difficulty of tracing the distribution of the new wave of illegal minors. The difficulty derives from the federal authorities’ refusal to disclose where this year’s wave of illegal Central American minors has been distributed. He observes that the “EV-D68 epidemic suddenly appeared in Missouri, Colorado and Chicago in the second week of August, sometimes even before schools opened.”
Munro then explores the nature of the outbreak:
There are three genetically distinct subtypes of EV-D68. These subtypes are technically called “clades” and all three are apparently contributing to the 2014 epidemic.
TheDC asked Oberste — the top CDC official — if all three clades are involved in the epidemic.
“In the current outbreak, there is one major group/clade which contains the vast majority of viruses, a minor group/clade that is related to the major group, and an outlier group/clade that has only a few viruses in it,” the CDC replied.
That’s critical information, because viral epidemics are usually powered by one new variety of a familiar virus. For example, the annual flu epidemics usually consist of a new mutation of an older flu virus. Because it is new, it bypasses immune responses that people acquired during prior flu waves, and then quickly jumps from person to person across the United States.
If confirmed, the presence of many strains would be further evidence that a population movement triggered the outbreaks, said Eden Wells, an assistant epidemiology professor at the University of Michigan’s School of Public Health.
