Joseph Eisenberg, Ph.D., M.P.H., chair of epidemiology at U-M School of Public Health, responds to the recent CDC warning of a cryptosporidiosis outbreak in public pools across the nation.

The number of reported outbreaks has increased an average of 13 percent each year from 2009 to 2017.

The parasite can't be killed with chlorine and is so small it easily passes through pool filters. 

“Internationally, this is one of the more important pathogens to be on everyone’s radar,” Eisenberg says.

Dr. Eisenberg provides insight on how to prevent the spreading of the illness, since it's difficult to prevent exposure to the parasite.
