The new cases were reported a day after New York City Mayor Bill de Blasio announced mandatory MMR vaccinations for everyone living in Brooklyn's Williamsburg neighborhood - in one of the toughest measures against an outbreak in U.S. history.
"There are many more individuals who are living with chronic diseases, who are surviving cancer, and so we don't want children or adults to be unnecessarily exposed to measles" due to "measles parties".
The state of emergency banned anyone who is under 18 years of age and unvaccinated against the measles from public places in Rockland County. If New Yorkers fail to take up the offer, they face $1,000 fines. Mr. Sussman told local NY media that he hoped to file a lawsuit by Friday. Two of the infected children developed pneumonia and had to be hospitalized as a result.
Anyone who would like to receive a vaccine at one of these clinics should register in advance for an appointment at www.health.ny.gov/gotoclinic/60.
Ironically, it is the very success of vaccines which has led to our complacency to vaccination.
Westchester borders Rockland County, where measles cases have been concentrated among members of the ultra-Orthodox Jewish community. But they said they were taking additional steps to control the outbreak in advance of Passover, when some families may travel overseas to areas in Israel or Europe that are experiencing measles outbreaks.
Officials say 285 measles cases have been confirmed in New York City since the beginning of the outbreak, the largest in the city since 1991.
Mayor Bill de Blasio: The only way to stop this outbreak is to ensure that those who have not been vaccinated get the vaccine.
Video: Despite evidence that vaccines are safe and effective, the anti-vaccination movement is gaining strength. We will use it prudently, we will use it with restraint, but we will use it to protect the public health of Westchester people. Anyone who can not afford a vaccination will receive on for free.
Amler cautioned anyone who thinks they have measles to call their doctor and report their symptoms.
Governor of Washington Jay Inslee also declared a state of emergency in January, urging immunization and citing the measles outbreak as "an extreme public health risk", according to a CNN article.
"We try always to respect religious rights, religious customs, but when it comes to public health, when we see a problem emerge, we have to deal with it aggressively", de Blasio said.
A CDC report states that the US had a notifiable measles outbreak in 1912, resulting in around 6,000 deaths every year, until scientists developed the measles, mumps and rubella (MMR) vaccine in 1963. "You have a larger pool of babies".
"In order to prevent an outbreak in your community, you have to have a 97 percent herd immunity rate", Sheffield said.
City officials said that insured adults and children will be covered. Six of the children are siblings.
Meanwhile on Wednesday, officials in Westchester County just north of New York City announced that measles has been confirmed in eight children who were apparently exposed to the highly contagious virus while visiting Rockland County or Brooklyn.
