Marco's Morning Report — Sunday, August 23, 2026

Good morning, Marco. A quiet Saturday in the journals, a loud one at CDC. The agency posted a sprout outbreak that is carrying four separate pathogens on one vehicle — three E. coli strains plus a Salmonella — which is the kind of thing that breaks the mental shortcut you use at 3 a.m. when a gastroenteritis admit comes up from the ED. Measles crossed 2,777 with the elimination-status committee already reading the file. And the COVID curve may finally be flattening: 47 states growing instead of 50. The debate is close to home this morning — the property tax amendment on your November ballot got its wording rewritten, so it's worth knowing what you'll actually be voting on. Mets put up ten in Chicago.

One bag of sprouts, four organisms — the outbreak that doesn't fit the usual pattern

CDC and FDA announced a multistate outbreak tied to alfalfa sprouts grown by Everything Sprouts of Minneapolis and sold under the Calco and Everything Sprouts brands. Fifty-five people across fifteen states are sick, four hospitalized, no deaths. What makes it unusual is the microbiology: this is not one bug. Investigators have identified three distinct Shiga toxin–producing E. coli strains — O26:H11, O103:H25 and O168:H8 — plus Salmonella Agona, and two patients are infected with both an E. coli and the Salmonella at once. Most illness has clustered in Minnesota and Wisconsin. The company recalled 5-ounce containers distributed since May 27. CDC outbreak page · Washington Post

Why it matters to you: the non-O157 STEC serogroups are the ones that don't get caught by selective culture — they need Shiga toxin EIA or a GI panel, and plenty of labs still reflex to sorbitol-MacConkey out of habit. In an 80-year-old with bloody diarrhea and a raw-sprout exposure, the practical consequences of calling it STEC are immediate: no empiric fluoroquinolone, no loperamide, and a plan to recheck CBC and creatinine at 48–72 hours for HUS rather than sending them home from observation. Elderly patients tolerate the volume losses badly and are the ones you end up admitting.

Talking point: next time you have a diarrheal admit, ask what your lab's stool workflow actually does — Shiga toxin EIA on every specimen, or only on request. That answer determines whether these three serogroups are findable at your hospital.

Public health · CDC data, Aug 20

Update: measles at 2,777 — and the number that predicts next year is the kindergarten one

CDC's Wednesday update puts 2026 at 2,777 confirmed cases (up from 2,566 on Aug 13), across 36 outbreaks, with 94% of cases — 2,614 of 2,777 — outbreak-associated. Ninety-three percent of patients were unvaccinated or of unknown status; 7% have been hospitalized, down from 11% last year. The second number in the release is the more consequential one: MMR coverage among U.S. kindergartners has fallen from 95.2% in 2019–20 to 92.4% in 2025–26, leaving roughly 280,000 kindergartners unprotected this school year. Meanwhile the U.S. National Verification Committee is now reviewing CDC's annual report, with the finding going to PAHO's Regional Verification Commission for a formal announcement in November. CDC measles data · CIDRAP analysis

Why it matters to you: 92.4% is below the ~95% needed to hold herd immunity, and the gap compounds year over year — which means the adult measles exposures that land in your ED are a multi-year forecast, not a one-season blip. The other half of it is your own workforce: hospitals with unclear staff immunity records are the ones that end up furloughing people after an exposure event.

Suggested action: worth confirming your group knows the airborne-isolation trigger for febrile rash in an adult, and that employee health can produce measles titers for the night team on short notice rather than during a 2 a.m. exposure investigation.

Respiratory season · CDC, Aug 19–21

Update: the late-summer COVID wave may be topping out — 47 states growing, down from all 50

CDC's epidemic-trend modeling as of Aug 19 puts COVID as growing or likely growing in 47 states, not changing in two, and declining in none — a step down from Aug 12, when the model had all 50 growing. The South and West still carry the sharpest signal, with elevated wastewater in Florida, California, Texas and Hawaii, driven by the Nimbus lineage. At the same time, aggregate acute respiratory illness remains very low as of Aug 21, RSV is very low in most areas, influenza is low, and rhinovirus/enterovirus is the thing actually rising nationally. CDC Rt estimates · Respiratory data channel

Why it matters to you: "growing in 47 states" and "ARI very low" are both true, and that combination is exactly why the aggregate dashboards are useless for your admitting decisions right now. Two states flipping to flat is a small signal but it's the first directional change in weeks — and it lands in the middle of the vaccine gap, with the 2025–26 formula being wound down and 2026–27 not expected until late September. Your 65-and-over admits this month are, on average, further from their last dose than at any point since spring.

Suggested action: keep testing symptomatic elderly admits regardless of what the aggregate ARI line says, and note the vaccination interval rather than a yes/no when you take the history.

Section B — The Debate

One live argument, both sides, named voices.

Should Florida raise the homestead exemption to $250,000 on non-school property taxes?

Why it's live right now: on Aug 3, Leon County Circuit Judge David Frank ruled the ballot title and summary for Amendment 3 "clearly and conclusively defective" — the title, he wrote, doesn't state the amendment's legal purpose so much as endorse it, calling the phrasing "more akin to a political slogan." The Attorney General filed rewritten language on Aug 14. What was "Save Our Homes From Excessive Property Taxes" now reads "Increased Homestead Exemption; Lower Cap on Increases in Non-Homestead Property Assessments." Same amendment, plainer words — and every Lee County homeowner votes on it Nov 3.

The case FOR

Gov. Ron DeSantis, and the legislative sponsors of HJR 1-F

A tax you must pay every year to keep a house you already own is not really a tax on a transaction — it's a recurring charge for permission to stay, which is why DeSantis frames property taxes as homeowners "paying rent to the government." The argument's force comes from the mechanics: assessments rose with a historic run-up in Florida home values, so collections climbed sharply without any local government ever voting to raise a rate. Retirees on fixed incomes absorbed a tax increase generated by paper gains they can't spend. The amendment is deliberately narrow — it exempts the first $150,000 of assessed value in 2027 and $250,000 in 2028 from non-school taxes only, leaving education funding untouched, and indexes to inflation after. And rather than imposing it, the legislature sent it to a 60% voter threshold: if Floridians think the trade against local revenue is a bad one, they can say so.

The case AGAINST

Nicole Fox, policy analyst, Tax Foundation Center for State Tax Policy

Exempting most primary residences doesn't reduce what fire departments, sheriffs and stormwater systems cost — it only changes who pays for them. Fox's analysis argues the shift is "nonneutral": the burden moves onto businesses, renters and non-homesteaded owners, and pushes counties toward sales taxes, which are a poorer fit for funding local services and fall hardest on lower-income households. Legislative staff estimate the amendment reduces local revenue by roughly $4.6 billion in FY 2027–28, growing to about $8.4 billion in FY 2028–29 — and in a coastal county, "local revenue" means beach renourishment, drainage and hurricane response. The Florida Policy Institute's voter guide makes the related point that renters get none of the exemption and can be handed part of the cost.

Where it might land: Amendment 3 is on the Nov 3 general election ballot and needs 60% approval to pass; the exemption would take effect in 2027 if it does.

Section C — On My Radar

Noteworthy, not urgent.

Mets 10, White Sox 5 (Aug 22). Luis Robert Jr. went deep twice against his former team, with Bo Bichette, Carson Benge and Luis Torrens also homering — five home runs and 16 hits against a Chicago staff that struggled start to finish. Mets to 59-71. ESPN

Iran calls the new sanctions a "declaration of war" on all nations (Aug 22). Tehran's foreign ministry says the latest U.S. measures are an attempt to exert extraterritorial sovereignty over other UN member states; Mohsen Rezaei of the Supreme National Security Council warned neighboring countries they'd be treated as enemies if they join the pressure campaign. Trump said he now views the Strait of Hormuz "as an American territory." China's foreign ministry spokesman Lin Jian said sanctions "will not help resolve the issue." Al Jazeera

Cuba: nine more state companies sanctioned (Aug 20–21). Treasury and State named nine state-owned mining, metal and construction firms plus the leadership of ICAP, the Cuban Institute of Friendship with the Peoples, and broadened enforcement against Americans who visit and transact with government-affiliated businesses — including detentions of travelers returning from the island.

Puerto Rico's water emergency continues, and Bad Bunny closes out at Hiram Bithorn. The island-wide emergency has parts of San Juan and surrounding municipalities on rotating 48-hour shutoffs amid extreme drought and an aging system, with heat indices near 110°F on the coast. The Debí Tirar Más Fotos tour finales run last night and tonight in San Juan. Consequence

Jalapeño Salmonella Javiana holds at 431 cases, 57 hospitalizations, 32 states. No new CDC numbers since the Aug 19 update that added 86 cases and five states; illness onsets run Jun 19–Aug 2, and 93% of those interviewed ate at a Mexican-style restaurant. The Sinaloa grower is still unnamed. CDC

Golf tech: nothing new in 48 hours — day 22. Pipeline unchanged: Shot Scope's $200 LM1, the sub-$800 Par Breaker Swing Pulse X10 with dual-camera plus radar, Uneekor's AI swing work, and the year-end Rapsodo PC sim. The interesting movement is software, not hardware. The Golf Wire

Section D — Trends to Watch

One vehicle, several organisms — foodborne investigations are outgrowing the one-bug frame. The sprout outbreak carries three E. coli serogroups and a Salmonella, with co-infections. Whole-genome sequencing is now sensitive enough to resolve what used to be reported as a single event, which means "what grew?" is becoming a worse question than "what was the exposure?" For an admitting physician, the exposure history is doing more diagnostic work than it used to.

Vaccine coverage is a leading indicator; case counts are a lagging one. The measles release pairs 2,777 cases with a kindergarten coverage figure that has slipped 2.8 points in six years. The case count describes last winter's coverage. The coverage number describes the next several years, and it's the one nobody reacts to.

Aggregate respiratory dashboards are decoupling from their components. "ARI very low" and "COVID growing in 47 states" coexist because the summer wave sits inside a trough for everything else. The composite metrics designed for a November-to-February season are steadily losing their usefulness as triggers.

Ballot-language litigation as a policy battleground. A Florida judge striking a constitutional amendment's title for advocacy — and forcing a neutral rewrite eleven weeks before the vote — is a reminder that in high-stakes referenda the fight over sixty words of summary can move as many votes as the campaign does.

Section E — Ideas & Opportunities

Bring the census-versus-consecutive-days question to the group. The Kruer Journal of Hospital Medicine paper found the odds of a decision-fatigue event were 1.58× higher above a median census of 13, with each additional patient adding about 10.7% — and days-in-a-row was not the driver. Hypoglycemia was the most common flagged event. Whenever your group next argues about night caps, that's the citation, and it points at volume rather than block length.

One question for the lab. Does your stool workflow run Shiga toxin EIA or a multiplex GI panel on every specimen, or only on request? Three of the four organisms in the sprout outbreak are non-O157 and are invisible to a sorbitol-MacConkey-only pathway.

Read before November. The revised Amendment 3 ballot text is two paragraphs long and now says what it does. Ten minutes with it and the Pinellas County Property Appraiser's FAQ is enough to know what you're voting on and what it does to Lee County's budget.

Section H — Background / Already Covered

Older than 48 hours, or previously reported

Decision fatigue in hospital medicine (JHM, Kruer et al.). Retrospective review of more than 1,000 shifts worked by 43 full-time day hospitalists at two Midwest hospitals in Jan–Feb 2022, looking for markers of impaired decision-making: pharmacologically antagonistic medication pairs, hypoglycemia, and potential overuse of transfusion, imaging and penicillin alternatives. 220 flagged events; none occurred on about three-quarters of days. Odds of an event 1.58× above a census of 13 (p = .002); OR 1.107 per additional patient (95% CI 1.022–1.198). Covered by Medscape Aug 18.
Heidi Overton nominated to lead FDA (Aug 19). White House Domestic Policy Council deputy director, Johns Hopkins-trained general surgeon, former White House fellow. She'd inherit an agency down more than 3,000 staff, and has helped shape the administration's vaccine, food and drug-pricing policy. Senate confirmation required.
NYC Legionnaires', Upper East Side: 9 deaths (announced Aug 14). Health Commissioner Alister Martin says the source has been eliminated and there have been no new diagnoses in more than three weeks; the two most recently announced deaths were diagnosed weeks earlier. Seventy-six cooling towers tested positive across the Upper East Side plus one on the Upper West Side. A separate Central Harlem cluster reached five deaths earlier this month.
FY 2027 IPPS final rule. Issued Jul 31, published in the Federal Register Aug 4, effective Oct 1. Net inpatient rate update +2.3% (3.2% market basket less a 0.9-point productivity adjustment), about $2.9 billion more than FY 2026. CJR goes national with mandatory participation from Jan 1, 2028. Medicare-Dependent Hospital payments and the low-volume adjustment expire Dec 31, 2026 absent legislation.
ED boarding's second clock (JAMA/RESQUE-NET). Covered Aug 22 — 17.3% of 492,135 general-medicine admissions went four-plus hours before an inpatient team assumed management. No new developments.
Hormuz, running background. Blockade and counter-blockade continue; Iran–Oman route coordinates agreed Aug 5, talks described as final-stage but conditioned on sanctions relief, asset release and compensation. UKMTO reports shipping still at reduced levels with continued harassment.
Knicks: out of season, out of the report until next spring's playoffs.
