The mayor of El Paso calls for quarantine at the U.S.-Mexico border due to a perceived typhus threat.
Date: 1916
El Paso Mayor Tom Lea Sr. writes a telegram to the U.S. Surgeon General on June 17, 1916 demanding a quarantine policy to protect his city from the typhus he believes is being spread by the hundreds of "dirty lousey [sic] destitute Mexicans" arriving every day.
A medical inspection will be added to the border crossing protocol the following year and will remain until the "threat" of a typhus spread has passed, well into the 1930s.
