In 1952--an epidemic year for polio--there were 58,000 new cases reported in the United States, and more than 3,000 died from the disease. Thanks for this reminder, Sally. How well I remember the day this discovery was announced--and how very happy everyone was about it! What a great day that was!!! Barbara V.
