Current Events-Bacteria Outbreak?

http://www.msn.com/en-us/news/us/wisconsin-officials-investigating-infectious-outbreak/ar-BBqlysI?ocid=spartanntp

This whole article seems a bit suspicious...starting with the "bacteria" name...Elizabethkingia anophelis. 

Then, this excerpt:

So-called disease detectives from the Centers for Disease Control and Prevention (CDC) have been called in to help find the source of the infection.

"So-called"? IS there such a thing as a CDC detective? If so, is the journalist ridiculing the notion thereof? In Brazil, where apparently there is a disease outbreak, there ARE zika police. What if that were to happen in the US?
