What people are saying verbatim
“We will review measles rates for the nation. These data are public and show a runaway train.”
Noel Brewster, PhD, Chair, CDC measles elimination committee · Stat First Opinion (cited in CDC coverage) · Aug 6
“One of the most worrisome is the ongoing outbreak in Utah, which apparently has gone on for more than 12 months, the main criterion for loss of elimination.”
Noel Brewster, PhD, Chair, CDC measles elimination committee · Stat First Opinion (cited in CDC coverage) · Aug 6
“Elimination status marks whether a country has stopped sustained domestic transmission. Losing that status would signal a consequential reversal, evidence that the systems and protections that once kept measles at bay no longer do.”
Noel Brewster, PhD, Chair, CDC measles elimination committee · Stat First Opinion (cited in CDC coverage) · Aug 6
“Measles is the most contagious virus known to humankind. A single infected person can spread it to many others before they even realize they are sick.”
Lancaster County Commissioner, Opinion column author · Lancaster Online · Aug 7
