Israel is in the midst of a massive, emergency immunization drive of all children under the age of 9 against polio.
Health workers detected the virus in southern Israel in February. Since then, they've found it in 85 different sewage samples across the country, the Global Polio Eradication Initiative said Wednesday. Yet so far, no children have gotten sick or been paralyzed by the virus.
Measles was declared eliminated in the U.S. more than a decade ago. But in recent years, the highly infectious disease has cropped up in communities with low vaccination rates, most recently in North Texas.
There, 21 people — the majority of whom have not been immunized — have gotten the disease, which began at a vaccine-skeptical megachurch.
The outbreak began when a man who contracted the virus on a recent trip to Indonesia visited the Eagle Mountain International Church in Newark, about an hour and a half northwest of Dallas.
A 7-year-old vaccine that has drastically cut intestinal infections in infants is benefiting the rest of America, too.
A study published Tuesday from the Centers for Disease Control and Prevention shows that vaccinating infants against rotavirus has also caused a striking decline in serious infections among older children and adults who didn't get vaccinated.
