Idaho recently recorded its first case of Zika virus in a woman who recently traveled to Mexico.
But could Zika actually thrive in Idaho?
A recent study in Brazil indicates it might be possible. Local experts say the concern is the Culex mosquito, which is common in the Gem State.
"It is possible Culex can contract Zika and transmit it," said Sam Holt, with Ada County Mosquito Abatement.
At the Ada County Abatement District, what was certain one day, seems to change the next.
"A lot of times, lately, we see breaking news about Zika," said Holt.
The Brazilian study received a lot of attention, but the Centers for Disease Control says it is the only study showing Culex is capable of carrying and transmitting Zika.
"They claim that they are able to infect culex,” said Holt. “But they're the only ones who claim to have done this in the world."
The C.D.C. says it is highly unlikely Zika could thrive in Idaho.
