Historically, the island has been uninhabited due to its location and distance from the mainland. Originally, the monkey colony now located on Morgan Island was located in La Parguera, Puerto Rico at the Caribbean Primate Research Center.[1] According to the Center for Disease Control and Prevention (CDC), there were incidents of the free-ranging monkeys that were infected with the herpes B virus escaping. The CDC report stated that there were outbreaks among locals when the monkeys became overpopulated. Puerto Rico was alarmed by this, and South Carolina stepped in to offer an island for research. South Carolina offered uninhabited Morgan Island for the monkeys to be housed. In 1979, over 1,400 animals were relocated to Morgan Island.[1]
