WASHINGTON – The Centers for Disease Control and Prevention is urging Americans young and old to get vaccinated against measles because of a sharp uptick in cases in the new year.
Eighty-five people in 14 states have contracted the contagious respiratory disease in the first 28 days of 2015.
That’s “as many cases as we have all year in typical years. This worries me,” said Dr. Anne Schuchat, director of the CDC’s National Center for Immunization and Respiratory Diseases.
The vast majority of cases – 63 – are in California and stem from an outbreak that began at Disneyland Park in Anaheim.
Visitors to the park between Dec. 17 and Dec. 20 of last year later developed the disease along with at least five Disney employees. To date, 67 cases in California and six other states have been traced to the Disney outbreak.
“We don’t know exactly how this outbreak started, but we do think it’s likely a person who was infected with measles overseas visited the Disney park in December while they were still infectious,” Schuchat said Thursday during a telephone briefing with reporters.
In addition to the 63 cases in California, Arizona has reported seven cases, while Washington has had two and New York has reported three.
Colorado, Nebraska, Oregon, Utah, Minnesota, Illinois, Pennsylvania, South Dakota, Texas and Missouri have reported one case each.
New York State health officials said Friday that Amtrak passengers on a Niagara Falls bound train may have been exposed to the measles virus this week from a college student traveling from Penn Station in New York City to Albany.
The student was on train No. 120 on Jan. 25, and was diagnosed at Bard College in Dutchess County, the state Health Department reported .
Public health officials advised anyone who was on the train, which continued on to Niagara Falls, who is not immune to measles or not sure of their immunity to contact a physician if they become ill with fever.
They also cautioned that anyone with symptoms consistent with measles call a physician or emergency room before seeking care to protect others from being exposed to the disease.
This is the third case of measles this year in the state. Two others were diagnosed in New York City.
Growing in cells at the back of the throat and lungs, measles is spread through the air by coughing, sneezing and even breathing. It can cause fever and cold-like symptoms, along with a stubborn rash.
Before the U.S. measles-vaccination program, which began in 1963, 3 million to 4 million people in the United States developed measles each year, leading to 48,000 hospitalizations and 400 to 500 deaths.
As measles vaccinations took off in the 1960s, the rate of transmission steadily declined. The resurgence of the disease is a disturbing development for health officials, who declared in 2000 that measles had been eliminated from the United States through a successful vaccination program.
Between 2001 and 2010, the United States reported a median of 60 cases a year, Schuchat said.
But unvaccinated Americans and foreign visitors who traveled to the Philippines, Europe, Africa and Asia are the main culprits in a growing case spike that began several years ago and exploded in 2014.
More than 600 measles cases were reported in the United States last year, the most in more than 20 years. Schuchat said a growing trend of Americans foregoing measles vaccinations for personal and religious beliefs has helped fuel the recent U.S. outbreaks.
At one point last year, 90 percent of U.S. cases were among people who hadn’t been vaccinated for the disease or who didn’t know their vaccination status.
One in 12 U.S. children do not get their measles vaccination on time, Schuchat said.
“This is not a problem of the measles vaccine not working,” Schuchat said. “This is a problem of the measles vaccine not being used.”
Children should get their first measles vaccine at 12 months with a second dose no later than age 4 to 6. Adults who aren’t sure of their vaccination status should also get two doses.
Schuchat said critics’ concern that the measles vaccine causes learning problems and autism in children “just have not (been) borne out at all.” She said the vaccine is safe and effective.
About 10 percent of children who get measles also get ear infections, and about 5 percent develop pneumonia. About one in 1,000 measles patients contract encephalitis, and one or two out of 1,000 die.
The CDC is urging health professionals to suspect measles when they see patients with rashes and other measles symptoms. They’re also being asked to check patients’ travel history to see if they have visited countries like Azerbaijan, Indonesia, India and Qatar, where some of the current U.S. cases appear to have originated.
