The Hudson Valley is asking President Trump to help stop the ongoing measles outbreak.

Rockland County Executive Ed Day wrote the President asking that an executive order be issued or a law passed that would ban unvaccinated visitors from other countries from entering the United States.

"We need action on the federal and state level now. To start, we must recognize that our outbreak started with seven visitors from overseas who were infected with the measles and that there are at least 5 countries with significant measles issues," Day wrote on Facebook after news broke he contacted Trump.

As of Thursday, there are 302 confirmed cases of measles in the Hudson Valley, according to the New York Department of Health.

Day told WCBS 880, his proposal is common sense adding other counties require certain immunizations before entering the country.

"We must ensure that visitors to our Country from overseas produce proof of immunization and/or immunity from diseases deemed potentially harmful to those living here," Day said on Facebook. "Doing nothing is not an option and a gross disservice to the people of our Country."

There have been 247 confirmed cases of measles in Rockland since October 2018. Elsewhere in the Hudson Valley, there are 35 confirmed cases of measles in Orange County, 17 in Westchester County, two in Sullivan County and one in Greene County, the New York Department of Health reported on Thursday.

Measles is a highly contagious respiratory disease caused by a virus that is spread by direct contact with nasal or throat secretions of infected people. People first develop a fever, then often a cough, runny nose and watery eyes, followed by an appearance of a rash. People are considered infectious four days before to four days after the appearance of the rash.

Symptoms include a fever, rash, cough, conjunctivitis or a runny nose. Symptoms usually appear 10-12 days after exposure but may appear as early as seven days and as late as 21 days after exposure.

In October, it was reported an international traveler with measles visited multiple locations in Rockland and Westchester counties. Among the locations infected with measles was the Costco in Nanuet and Westchester Medical Center.

Around Thanksgiving, shoppers at the Palisades Mall were potentially exposed to measles.
