State health officials say polio has been found in wastewater samples taken from both Rockland and Orange counties, calling this development “just the tip of the iceberg of much greater potential spread.” The New York State Department of Health says samples taken from two different locations in Orange County in June and July tested positive. The CDC found three positive samples from Rockland and four from Orange County that are genetically linked to the single human case found in a Rockland County resident. The findings suggest local transmission. As such, area health officials are urging those who are not immunized to get vaccinated now. State Health Commissioner Dr. Mary Bassett said that for every single case of paralytic polio, there may be hundreds of other people infected. As of August 1st, among children who are two years old or younger, Rockland has a polio vaccination rate of about 60 percent and Orange County, 59 percent. That’s compared to the statewide average of nearly 80 percent. Learn more about polio and the vaccine at health.ny.gov/polio.
