Measles is really, really contagious — 90% of susceptible people exposed to an infected person will become infected, according to the CDC. Therefore, it’s understandable why some may be concerned about whether they are still immune, especially if they got the vaccine decades ago.
Some health experts also fear the potential long-term impact from this resurgence of measles and the risk it could pose to vulnerable populations, like infants who have yet to receive the vaccine or people with weakened immune systems from an underlying illness.
Either way, the fear is that measles could become commonplace if things continue the way they have been.
“If it keeps going, there won’t even be any point in reporting individual exposures anymore because we will wind up assuming measles is all over, or endemic,” said Dr. David Cennimo, an infectious disease expert at Rutgers New Jersey Medical School.
Meaning, if we don’t get this under control, measles will no longer be headline news. It will be the norm. Cennimo is among the health experts concerned about the impact of the growing anti-vaxx movement.
