On Monday, the World Health Organization (WHO) also released a report stating that the number of reported global cases of measles has increased by 300 percent in the first few months of 2019, in comparison to the same period of time previous year.
The Centers for Disease Control and Prevention recommends that all children get two doses of measles vaccine, which is 97% effective.
"Preliminary global data shows that reported cases rose by 300 percent in the first three months of 2019, compared to the same period in 2018. This is the second-greatest number of cases reported in the United States since measles was eliminated in 2000", the CDC said in a statement.
"While this data is provisional and not yet complete, it indicates a clear trend".
According to the CDC, all of these outbreaks are linked to travelers who brought measles back from other countries such as Israel, Ukraine, and the Philippines, where large measles outbreaks are occurring. "These cases were imported from other countries, but because of low vaccination coverage in these communities, measles is spreading widely throughout these communities". There have been no reports of any deaths from the disease in the United States this year or last.
But rich countries with seemingly high vaccination rates are seeing cases spike too.
"When you make the decision not to vaccinate your child, please understand you're also making that decision for the people around your child", New York City's Deputy Mayor of Health and Human Services, Herminia Palacio, told NPR on Wednesday.
The Brooklyn outbreak is believed to be driving a nationwide surge in infection that is on pace to set a record for most illnesses in 25 years.
Global measles cases are rising for the third year in a row, the World Health Organisation (WHO) said, reporting that recorded cases between January and March were 300 per cent higher than in the same period last year.
If the outbreaks aren't brought under control, public health experts worry that the cases in 2019 will hit a record almost two decades after measles was "eliminated" in the United States. The highest number of reported cases since 2000 was 667 in 2014, according to the CDC.
After the vaccine, cases plummeted, with 963 cases in 1994.
The majority of the new cases are connected to an outbreak in New York City and New York State, Cohn says.
Of those, 273 were reported this year, including 44 cases since last week, when New York City officials declared a public health emergency and ordered mandatory measles vaccinations to halt the outbreak concentrated among ultra-Orthodox Jews in Brooklyn.
World Health Organization said that the most dramatic rise in cases - a 700-percent increase compared to previous year - has been reported in Africa, which has weaker vaccination coverage than other regions.
