The number of suspected and confirmed chikungunya cases by local transmission climbed to 10,341 total the health agency noted. This is up from 9,446 cases the week prior.
The total fatalities linked to the mosquito borne virus remains at three on in the US territory.

Chikungunya is a viral disease transmitted by the bite of infected mosquitoes such as Aedes aegypti and Aedes albopictus. It can cause high fever, join and muscle pain, and headache. Chikungunya does not often result in death, but the joint pain may last for months or years and may become a cause of chronic pain and disability. There is no specific treatment for chikungunya infection, nor any vaccine to prevent it. Pending the development of a new vaccine, the only effective means of prevention is to protect individuals against mosquito bites.
