For the first time, Aedes aegypti mosquitoes have been found in Oregon. Emilio DeBess is the state public health veterinarian based at the Oregon Health Authority’s Public Health Division.

He says the insects are a national concern ”because they can carry and transmit various diseases that can have serious health consequences such as Zika virus, chikungunya, dengue and yellow fever.”

The insect was found this summer in Jackson County while officials were monitoring other kinds of mosquitoes. Officials are continuing surveillance and OHA is working with other states to learn more about it. Infection risk from the mosquito is currently low.

The insect, also known as the yellow fever mosquito, was found in California in 2013 and has been progressing northward since. DeBess joins us with more on this mosquito, why it’s important to track these insects with county and federal agencies like the Centers for Disease Control and Prevention, and how changing climates are playing a role in the insect’s spread.
