Question

Naturally-occuring poliomyelitis has occurred as recently as 2007 in the Americas.a) Trueb) False

Answer 1

The answer is: b) False.

Step-by-step explanation:

Polio is a contagious and historically devastating disease that was virtually eradicated from the western hemisphere in the second half of the 20th century.

At the peak of the polio epidemic in 1952, approximately 60,000 cases and more than 3,000 deaths were reported in the United States alone. However, with mass vaccination, polio produced by natural infection, was eradicated from the United States in 1979 and from the western hemisphere in 1991.

The answer is: b) False.
