Statutory health exclusion began with the Immigration Act of 1891, which barred “‘persons suffering from a loathsome or a dangerous contagious disease’”. Insanity was described “as a deranged condition, characterized by delusions, depression, or homicidal tendencies”. In 1907, the premise of exclusion based on mental health was expanded with the addition of “imbeciles, the feebleminded, and the physically or mentally defective." The
Immigration Act of 1917 added the “classification of constitutional psychopathic inferiority” and lowered the criteria to be classified as insane to one previous attack of insanity (compared to previous two or more in 1907). This led to an increase in the percentage of rejected immigrants that were rejected based on medical criteria from two percent in 1898 to 57 percent in 1913 and finally to 69 percent in 1915. The inferior stock mentality was adopted in the quota system of the
Immigration Act of 1924, which marked the beginning of examination of immigrants in their home countries. In the
Immigration and Nationality Act of 1952 (INA), seven of the 31 grounds for exclusion were health-related. A few decades later, under the
Immigration Act of 1990, the health related grounds were “streamlined and modernized all of the grounds for inadmissibility into nine broad categories”. Under the act, “Congress recodified the health-related ground for inadmissibility to include any alien “who is determined (in accordance with regulations prescribed by the Secretary of Health and Human Services) to have a communicable disease of public health significance”. In 1993, the National Institutes of Health Revitalization Act added
HIV as excludable. This was done by a Congressional amendment that added exclusion based on “’infection with the etiological agent for acquired immune deficiency syndrome’”. HIV was later removed from the exclusions in 2009 and effective by law on January 4, 2010. The vaccination requirement was added with the
Illegal Immigration Reform and Immigrant Responsibility Act of 1996. Vaccinations were required for “nine ‘vaccine-preventable diseases’” including: “mumps, measles, rubella, polio, tetanus and diphtheria toxoids, pertussis, influenza type B and hepatitis B”. ==Historical inspection process==
