The mosquito was found in the 89032 ZIP code area of Clark County which is in North Las Vegas.
"It is hard to predict how extensive the Zika virus spread will be in the USA this summer, but based on our experience with related mosquito-transmitted viruses, we might expect to see pockets of local transmission in areas of Texas and Florida, but more extensive spread is unlikely", Lazear said. The same type of insects have been detected in California and Arizona, where tests for the Zika virus have come back negative, officials said. "The mosquito then needs to live long enough to bite someone after the virus has had time to multiply in its system", Health District officials said in a news release.
But health experts said Southern Nevadans should not be too alarmed.
"We bait them with carbon dioxide and something that smells like humans, they have a little fan that sucks them in", said Chris Reisinger an environmental analyst with Mosquito Control.
"We have boots on the ground trying to figure this stuff out", she said.
Officials say the disease has not been transmitted by mosquitoes in Maryland.
Labus said it's possible the mosquitoes have been here all along but are so rare that they have not previously been detected. They were all contracted while travelling.
Reszetar said the mosquitoes aren't a reason for panic, but people should take more caution in keeping their yards clean and eliminating any standing water that mosquitoes require for breeding.More news: YouGov poll one week before election predicts hung parliament

This year Palm Beach County reports three confirmed travel-related cases of Zika.
Miami-Dade County was the focus of much of the state's efforts past year to combat Zika, which is particularly unsafe to pregnant women because it can cause neurological defects in developing fetuses.
"We have conducted active surveillance for the Aedes mosquito since 2014", said Dr. Joe Iser, Chief Health Officer of the Southern Nevada Health District.
Except the three laboratory-confirmed cases reported from Ahmedabad, no other case for Zika virus has tested positive, confirms the government.
The health district said it will ramp up its surveillance to determine how many mosquitoes might be in the area. Nearby residents will also be getting information on how to prevent breeding.
Clark County and the health district teamed up to record a panel discussion on mosquito dangers and educate residents about ways to protect themselves.
