“The risk of measles infection sometimes gets overlooked with the passage of time and how far most Americans are from seeing measles,” Dr. Schwartz said.
Measles typically begins with a fever, cough, runny nose and watery eyes, as well as a rash that usually first appears on the face and then spreads downward.
About 20 percent of unvaccinated people who are infected are hospitalized, according to the C.D.C. Complications are more common among pregnant women, those with weakened immune systems and babies and young children, whose immune systems are still developing.
“This is not a run-of-the-mill common cold,” Dr. Handy said.
As many as one out of every 20 children infected with measles will develop pneumonia, according to the C.D.C. One out of every 1,000 children get brain swelling, which can lead to blindness, deafness or seizures. In extremely rare cases, Dr. Ratner said, measles can also cause a progressive and fatal neurological disease that develops several years after an infection.
And one to three out of every 1,000 children infected with measles will die.
Today, measles still kills an estimated 100,000 people — most of them children — around the world each year.
Dr. Handy, who has young children, said measles is concerning to her both as a doctor and a parent.
“I know what to worry about,” she said. “And measles terrifies me.”
