A harmful viral illness transmitted by mosquitoes has seemingly landed in Arizona. Earlier this week, well being officers reported {that a} Maricopa County resident just lately contracted dengue, whereas routine surveillance has discovered traces of the dengue virus in no less than one close by mosquito inhabitants. These discoveries recommend that the an infection could possibly be spreading regionally within the state for the primary time, although the investigation continues to be ongoing.

Although there have been instances of dengue reported in Arizona earlier than, they’ve been present in individuals who doubtless caught it whereas just lately touring to international locations the place the illness is endemic. However given the surveillance information, officers say, it’s attainable that that is the primary regionally transmitted case of dengue to be reported within the county and the state as an entire.

“Whereas earlier dengue instances in Maricopa County have been associated to journey to international locations the place dengue generally happens, it is very important perceive if others may have been uncovered or if that is an remoted incident,” mentioned Nick Staab, medical epidemiologist, in a assertion launched by the MCDPH. “That is along with our routine investigations of anybody suspected to have dengue or different mosquito-borne ailments.”
