National Board of Health
The National Board of Health (NBH) was a short lived institution that operated from 1879 to 1883 in the United States. It was created during the third Session of the 45th Congress, listed as chapter 202 better known as the Public Health Act of 1879. The purpose of the NBH was to carry out a piece of legislation passed in Session I of the 45th Congress, Chapter 66. Chapter 66 and Chapter 202 were redundant pieces of legislature in all aspects but one: the implementation and oversight of the NBH.
The NBH was created during a period of emergency and had substantial powers (such as the ability to mandate quarantine). As the subsequent years were relatively pandemic-free, Republican members of Congress, as well as conservative lawmakers, chose not to reauthorize the NBH in 1883.
