Health officials announced on July 21 that a young adult in Rockland County, New York, had been diagnosed with polio in June. The person had never been vaccinated against the virus, officials said, and suffered paralysis as a result of the disease. Health experts are calling it a “wake-up call,” but they don’t think the single case or subsequent viral detection will lead to a country-wide outbreak akin to COVID-19 or monkeypox, as over 90% of the country’s young children are vaccinated against polio. Experts, however, say pockets of unvaccinated people across the country may be at risk. The best way to prevent further transmission in vulnerable communities is through vaccination, health experts say. Officials urge parents to make sure their children are current with their vaccines. An April report from the CDC found coverage among kindergartners for the 2020-2021 school year fell by 1% due to disruptions from the COVID-19 pandemic.
