DPHSS reports first locally acquired case of dengue fever on Guam in 75 years

Since 2019, there have been 23 dengue fever cases on the island.

The Department of Public Health and Social Services has reported the first locally acquired case of dengue fever on Guam.

According to DPHSS, on September 10, 2019, an alert physician reported a suspect case of dengue fever in a patient with no travel history outside Guam.

On September 11, 2019, the Guam Public Health Laboratory confirmed the first locally acquired case of dengue fever. The virus is type III [DENV 3], the same type of dengue virus causing outbreaks in Yap, Palau, Marshall Islands, and the Philippines.

According to DPHSS, this is the first locally acquired dengue case detected and reported on Guam in the last 75 years as all previous cases were imported from off-island.

In response, DPHSS said it is implementing a heightened response in preventing further local transmission of the virus.

The department has activated its Arboviral Disease Response Plan, which includes the following:

* Activation of the Public Health Incident Command;
* Enhanced surveillance for dengue fever;
* Targeted vector control including fumigattion of areas at high risk for mosquito transmission;
* Updating of dengue case management; and
* Community outreach and awareness.

All health care providers have been asked to be on alert for additional cases of dengue fever. A physicians’ alert has also been disseminated.
