No new dengue cases on Guam in over 4 months


The Guam Department of Public Health and Social Services (DPHSS) has not received any laboratory-confirmed cases of dengue fever in more than four months. The last two local sporadic cases of dengue fever occurred more than a month apart in January and February 2020.

There were a total of 22 cases in 2019 (13 locally acquired and 9 imported cases), including cases from the September 2019 outbreak.

DPHSS will declare another dengue outbreak when the number of locally acquired confirmed cases is three (3) or more in a two-week period.

The public is urged to continue prevention efforts and clean up trash, water containers and other mosquito breeding areas to protect themselves. This is particularly important with the rainy season.

The Guam Public Health Laboratory (GPHL) conducts tests for dengue including serotyping. The GPHL is on the third floor of the RAN-CARE Building at 761 South Marine Corps Drive, Tamuning, Guam 96913. For more information, contact Anne Marie G. Santos, GPHL Laboratory Administrator via email at

Providers should continue to be vigilant and report suspect dengue cases to the DPHSS Epidemiology and Laboratory Capacity (ELC) Program by FAX: 300-7355 and by email to the Territorial Epidemiologist:
