News of humans infected with Ebola in West Africa, avian influenza in China, polio in the Middle East, and dengue fever in the Caribbean are examples of reports that heighten concerns about the health screenings of people arriving in the United States. Under current law, foreign nationals who wish to come to the United States generally must obtain a visa and submit to an inspection to be admitted. One of the reasons why a foreign national might be deemed inadmissible is on health-related grounds. The diseases that trigger inadmissibility in the Immigration and Nationality Act (INA) are those communicable diseases of public health significance as determined by the Secretary of Health and Human Services (HHS).
