The Centers for Disease Control (CDC) have received at least 28 reports of measles infections in the United States in 2012. Seventeen of the patients are from Indiana. All but one of the Indiana cases were exposed at events held at the Woodland Country Club, Carmel, IN, February 9-11.
Measles became a reportable illness in N.Y. in 2008. New York City reported 29 of the 31 cases of measles in 2008. In 2009, all 18 cases of measles were reported from New York City. In 2010, the city accounted for 6 of the 8 reported cases.
Jeffrey Hammond from the NYS Health Department and Alexandra Waldhorn of the NYC Health Department were able to provide measles case counts for 2011 and 2012 today. In 2011 there were a total of 32 measles cases in New York, including 25 from New York City.
No reports of measles in New York residents have been reported to either agency in 2012. NYC has had two cases that were reported in visitors to the city.
On April 19, the CDC briefed reported on a surge in reports of measles cases in the United States for 2011. Measles cases are rare in the U.S. due to the routine and widespread immunization of children for the illness. In 2011, the CDC received reports of 17 outbreaks and a total of 222 cases of this highly contagious illness. This was the highest number of cases since 1996. Through April 21, the CDC has 28 reported cases of measles for 2012.
The CDC was able to track the origins of 200 of the measles cases to individuals who became infected overseas and then spread the illness when they returned to the U.S. Some 65 percent of the 222 patients with the illness had not been immunized and an additional 22 percent did not know if they had received the vaccine. 25 cases were in infants too young to receive the vaccine.
The Indiana measles outbreak involves sixteen people who attended one or more events at the Woodland Country Club in Carmel. Dr. Gregory Larkin, the state’s health commissioner, told NPR that all of those infected came from a number of families in the same social group. The first thirteen cases had all chosen not to be immunized.
Adams County, also in Indiana, had one report of a measles case in late February. The one case of measles was in an unvaccinated person who traveled to a nation where the illness is endemic.
Finney Couty, Kansas has six measles cases in January. Cases were also reported, in January, in the Detroit metro area by WJBK, in Riverside County, CA, and one case of measles was reported in Delaware.
