A Garan mining colony was located near Tak Tak space. In 2373, the USS Voyager received a distress call from the colony, requesting medical assistance. It was discovered that the colony had been infected by a macrovirus. The Tak Tak destroyed the colony to prevent the spread of the virus, but it had already been transferred to Voyager. (VOY: "Macrocosm")
