Lab-Confirmed Cyclosporiasis Cases Jump to Over 10,000

This represents an increase of nearly 4,000 cases over just the last week, from July 28 to August 5.

Key Highlights

  • Over 10,000 cyclosporiasis cases confirmed across 47 states since May, with Michigan and Ohio being the hardest hit.
  • Taylor Farms outbreak prompted a recall, with illnesses confirmed in multiple states including Illinois, Indiana, and Pennsylvania.
  • Tracking sources is difficult due to long incubation periods and limited genetic tracking tools for cyclosporiasis.
  • There have been 517 hospitalizations and two deaths related to the outbreak, emphasizing its public health impact.
  • Three states—Delaware, Hawaii, and Montana—have so far been spared from the outbreak.

Cyclosporiasis cases have reached 47 states in the U.S., and 10,468 cases have been lab-confirmed overall since May 1, according to reporting from USA Today.

There have been more than 3,700 cases confirmed since the CDC's last report on July 28. There are still at least 12,255 cases that have not yet been confirmed by laboratories, according to the CDC. There have been 517 hospitalizations and two deaths.

The latest outbreak has been traced to Taylor Farms, which prompted a recall from the company on July 17, as HPN reported on. Illnesses from this outbreak have been confirmed in Illinois, Indiana, Kansas, Kentucky, Michigan, Ohio, Oklahoma, Pennsylvania, and West Virginia.

The only three states that have been spared from the outbreaks so far are Delaware, Hawaii, and Montana. The hardest hit states are Michigan and Ohio; Michigan has reported over 11,000 cases (some of which have not yet been officially confirmed by the CDC). 

Sources of outbreaks can be hard to track because of cyclosporiasis's long incubation period, as well as difficulty obtaining samples and inability to use genetic tracking tools available for other pathogens like E. coli and listeria.
