MEASLES, CURRENT NUMBERS, PAST OUTBREAKS

Confidential to Your Thoughts on All This: Sorry we don't read the site in question and don't know many who do.  But for the latest Measles numbers, the NYS tracker/dashboard is available at Measles Dashboard

You might also try the Croton Historical Society for records of past Westchester outbreaks pre-and-post-vaccination. Google AI Mode has also been highly reliable. The Patent Trader used to chart measles back in the day. as many newspapers did. Good luck in your research.
