There is a second case of dengue fever in Guam.
The Marianas Variety reports this week's case was contracted by a person on Yap in the Federated States of Micronesia before they returned to Guam.
The first was contracted in Palau.
Guam's Department of Public Health said all dengue cases on Guam dating back to 1988 were contracted elsewhere and that transmission of the virus is not occurring on the island.
