For Sunday reading, I'm researching propaganda posters and found this article at Mother Jones discussing the war on STDs.

Army medical records dating back to the Revolutionary War show significant soldier losses due to venereal diseases. In a two-year period during the Civil War, the Union Army documented 100,000 cases of gonorrhea. During World War I, the Army lost 7 million person-days and discharged more than 10,000 men because they were ailing from STDs.

Yowza, well no wonder the US army handed out condoms like it was candy and declared Syphilis the enemy. They even said "women - stay away from Dance halls" and we could not escape the puns - the women were "BOOBY TRAPS", see.
