WSIL â€� At least 465 cases of measles have been reported in the United States since January 1, according to the latest numbers shared by the US Centers for Disease Control and Prevention on Monday.Ìý
That’s 78 more cases than the number reported last week and includes cases reported to the CDC by state health departments as of April 4, it therefore does not include cases reported since then.Ìý
According to the CDC, there are currently active outbreaks being monitored in California, Michigan, New Jersey, New York, and Washington.
Florida, Indiana, Massachusetts, and Nevada reported their first cases of measles this year, bringing the total number of states reporting cases to 19. The other states that have reported measles cases this year are Arizona, Colorado, Connecticut, Georgia, Illinois, Kentucky, Missouri, New Hampshire, Oregon, and Texas.
The total number of measles cases nationwide this year "is the second-greatest number of cases reported in the U.S. since measles was eliminated in 2000," the CDC says. That threshold was reached last week when the national total for the year surpassed last year’s total of 372. The largest outbreak was in 2014, when there were 667 cases reported nationwide due to several large outbreaks.Ìý
Measles is a highly contagious, vaccine-preventable respiratory illness characterized by a rash of flat red spots. Symptoms may include fever, cough, runny nose and watery eyes.Ìý
As of Thursday, 17 cases were reported in California. New Jersey health officials reported 13 cases for the year as of Friday. Seven cases have now been reported in Illinois.Ìý
Michigan reported 39 cases as of Friday, all but one of them in Oakland County.Ìý
Florida, New Hampshire, Nevada and Arizona each reported one case in March. Indiana health officials reported the first case of measles there on Friday. Massachusetts health officials also reported that state’s only 2019 case last week.Ìý
Washington state reported 78 cases in an outbreak that began in January. That includes individuals in Washington, Oregon, Hawaii and Georgia who all became infected in Washington.
(Hawaii is not included on the CDC list of states reporting cases because the cases there were reported by Washington.)Ìý
Oregon has also reported seven other cases that are not linked to that outbreak.Ìý
In February, Colorado, Kentucky, Connecticut and Texas all reported cases of measles.Ìý
Measles is endemic in many countries other than the United States. It is brought in when people who are unvaccinated or undervaccinated visit from a place where the virus is circulating or when people living in the United States visit such a place and return with an infection.Ìý
Health officials have said that the proliferation of anti-vaccine rhetoric has, in part, fueled an increase in the number of measles and other vaccine-preventable diseases in the United States.
