Governor Kathy Hochul said the disaster declaration allows health workers to immunise more people against the highly contagious virus. "No one should get seriously ill or die from a vaccine-preventable disease," Hochul said in a statement.
The outbreak in New York is part of a broader resurgence across the United States. Outbreaks have also been recorded in Texas, Utah, Ohio and South Carolina. Pennsylvania officials announced the state has recorded over 1,000 measles cases this year, the highest figure in the US since the early 1990s, when an outbreak in New York City exceeded that number over several years.
Health experts attribute the resurgence to a decline in vaccination rates below the 95 percent threshold needed to prevent community spread. Critics point to a growing anti-vaccination movement that has gained advocates inside the Trump administration, including Health and Human Services Secretary Robert F. Kennedy Jr.
The US had eliminated the domestic spread of measles by 2000. International officials from the Pan American Health Organization (PAHO) are scheduled to meet in November to assess whether the US and Mexico will retain their measles-free status.
