The Morbidity and Mortality Weekly Report's April 16 issue — Volume 75, No. 14 — ran two genetically distinct clusters of invasive Haemophilus influenzae type b disease among homeless and substance-using adults in Alaska, Oregon, and Washington. [1] It did not run anything on measles, now at 1,748 confirmed cases as of April 16 and 94 percent unvaccinated per the CDC's own data dashboard, or on bovine H5N1, which added five Idaho dairy herds on Monday. [2] Volume 75 Issue 15 drops Thursday.
The paper read Issue 14's omission yesterday as architecture rather than accident: the federal publication that used to carry bovine H5N1 lost the file to USDA in July 2025, and the measles file, still CDC's, is being allowed to sit. A second consecutive silent week would make the pattern harder to read as editorial lag. The MMWR's year-to-date 2026 output has run retrospective wastewater surveillance papers on 2024 and 2025 measles clusters [3] — historical, not contemporaneous. The 1,748-case current outbreak is absent from the vehicle whose stated purpose is to surface it.
What Thursday's issue carries will be read, in the paper's ledger, against what it does not. If Issue 15 runs a measles update, the silence resolves as two-week editorial delay. If it runs a further Hib or non-outbreak paper, the silence resolves as policy. The publication obligated to respond has one working day left before that choice becomes legible without ambiguity.
