CDC Is Ending Weekly Updates on the Cyclospora Outbreak. Indiana Stopped Counting Wednesday. Only Thirteen of the Forty-One Counting States Still Maintain a Page.

Yesterday I wrote that CDC’s Thursday numbers had not landed and said to watch the investigation page that evening. They did not land. Something else did. CDC’s outbreak investigation page now carries a September 3 date stamp, and the Key points include a line that was not there a week ago: CDC is reducing the frequency of web updates on this multistate outbreak as the number of new cases reported declines, and updates will no longer take place on a weekly basis.

The number underneath did not change. The Latest Update block still reads August 27: 11,458 laboratory-confirmed illnesses across twenty states, at least 495 hospitalizations, two deaths in Michigan, onsets from June 14 through August 15. FDA’s page is also still current as of August 27, same 11,458, same twenty states. Cyclosporiasis is the intestinal illness caused by Cyclospora cayetanensis, a parasite that reaches produce when human waste reaches a field or the water that irrigates it, and that washing does not reliably remove.

Two counters stepped back within twenty-four hours.

On Wednesday the Indiana Department of Health published 2,104 cases and said it would be the state’s final update until the official close of the outbreak. On Thursday CDC said its weekly rhythm was over. Indiana had been the most disciplined publisher in this outbreak. CDC’s Thursday update was the only federal number that moved on a schedule all summer, from 1,644 in July to 11,458 last week. Inside a day, both stopped. Both agencies still call the investigation open, and CDC says counting runs about six weeks past the August 31 close, into mid-October. The counting continues. The publishing does not.

I went looking for every state’s page this week. Thirteen of forty-one still keep one.

Forty-one states publish a 2026 count. Every number in the table below is now linked to its source, and sorting those sources is its own story. Thirteen states maintain a page or dashboard that has actually been updated on a schedule: Michigan, Indiana, North Carolina, New York, Kansas, Florida, Iowa, West Virginia, Arkansas, Wisconsin, Virginia, Washington and New Hampshire. Oklahoma runs a Tuesday dashboard I have not been able to link directly.

Seven more posted once and stopped. New Jersey’s number is from a July 11 press release. California’s is from July 14, Connecticut’s and Alaska’s from mid-July, Maine’s from an August 7 clinician advisory, Hawaii’s from an August 26 newsroom item. Those are announcements, not counters. Nobody has gone back to them.

The remaining twenty-one exist only in news coverage. Ohio, Missouri, Illinois, Kentucky, Texas, Nebraska, Pennsylvania, Massachusetts, Alabama, Colorado, Maryland, Minnesota and the rest hand figures to reporters or to an aggregator and post nothing themselves. Kentucky gives television stations a county-by-county breakdown and puts none of it on a website. Pennsylvania declines to give a county breakdown at all, citing confidentiality. Minnesota has a cyclosporiasis statistics page whose newest data is from 2018. Colorado updates a count every Monday that exists only in a spokesperson’s outbox. A person who got sick in Kentucky in July has nowhere to look.

The national case data has not moved since Tuesday, and Wisconsin was higher than I had it.

CDC’s case-data page still reads September 1: 18,445 laboratory-confirmed domestic illnesses since May 1, 990 hospitalizations, two deaths, forty-nine states plus the District of Columbia. Median onset July 8. Last season’s comparison is 1,180. Set the two federal series against each other and 6,987 confirmed illnesses this summer are attributed to nothing at all.

The West Virginia Office of Epidemiology and Prevention Services posted today: 315 cases as of September 4, unchanged from August 28, with 22 hospitalized. That is West Virginia’s first flat week. Going through the state pages also turned up a correction I owe the reader. Wisconsin has been at 284 cases with eight hospitalizations since August 26, not the 216 I have carried since August 5. The table is corrected and the fifty-state total moves from 33,457 to 33,525. Maryland and Colorado look low as well and I am rechecking both.

Here is where all fifty states stand, with CDC’s number beside each one.

Each count links to the source it came from. Compiled September 4, 2026, with the as-of date shown. Forty-one states publish a 2026 count and those sum to 33,525; nine publish none. Kentucky, Oklahoma and Tennessee are unlinked because the figures I carry are newer than the sources I have on file for them, and I am refreshing all three. Indiana’s figure is the state’s stated final update pending formal close. CDC attribution is from the outbreak map data table of August 27, 2026; a zero means CDC assigns that state no illness in the outbreak, not that it has none. The two series are built differently: CDC counts laboratory-confirmed illness tied to the lettuce by interview; states count every case reported in their window, some including probable cases, and Ohio, Iowa, Kansas, Arkansas and Kentucky on a calendar-year basis. Florida is shown on its May 1 series. Hawaii’s six include one investigated as locally acquired. Every count is a floor.

What is actually ending here.

Indiana froze its count on Wednesday. CDC dropped its weekly cadence on Thursday. Of the forty-one states counting, twenty-eight never maintained a page anybody could check. Two people are dead, 990 have been hospitalized, and nearly seven thousand laboratory-confirmed illnesses have no attributed source. An outbreak that is winding down still owes the public a number, on a day certain, where anyone can find it. Thirteen states manage that.

My September 3 post has the Michigan and Indiana numbers this one builds on.
