By 1918 a group called the Bureau for the Exchange of Information Among Child Helping Agencies was forming the basis for CWLA in 1920. In 1918 a pandemic mis-labeled “the Spanish Flu” (according to some historians it started in the U.S. mid-west), would cost the world between 20 to 50 million lives. The single worst outbreak in the United States was in Philadelphia when officials held a September 28, “Liberty Loan” parade in support of the war. Over 100,000 joined the parade and later over 12,000 people would die.
