What does this erratum notice mean for public health data?

If you're looking for new health findings, this isn't it. What you're reading is an erratum notice — essentially a correction published for a previous report from the Morbidity and Mortality Weekly Report. Errata are published when errors are discovered in already-published scientific documents. They're important for maintaining accuracy in the scientific record, but they don't present new research or health findings themselves. This particular notice corrects errors in Volume 70, Supplement 9 of the MMWR. The notice doesn't describe what those errors were, what data was affected, or what the corrected information shows. It simply signals that readers should be aware that corrections exist. Since this is purely a correction notice, there are no study results to report, no patient outcomes to discuss, and no safety information to consider. The main takeaway is straightforward: when you see 'erratum' in scientific publishing, you're looking at a correction, not new evidence.
