A tropical mosquito originally from Africa capable of carrying Zika virus, yellow fever and other tropical diseases was first discovered in Nebraska after it was caught late last month in a York County trap.
The State Health Ombudsman had looked at Aedes aegypti – a small black mosquito with white stripes on his back and legs – that had already established itself in parts of Kansas, Missouri and most of the southern stretches of the United States
But they were still surprised to find it so far north. "It was a shock," Dr. Tom Safranek, state epidemiologist, Tuesday. "It's a big surprise."
After identifying the first Aedes aegypti in a trap as part of the state's routine mosquito surveillance program, they presented more traps ̵
The insect was probably imported, hatching from eggs that had been attached to something brought to York County.
"How these things spread is that people move objects around from place to place," said Jeff Hamik, the state's entomologist for public health. The mosquito transmits deadly disease is low, Safranek said. It would have to bite someone who is already infected and then bite someone who was not. And Nebraska does not have a large population of people suffering from yellow fever, the Zika virus, chikungunya or dengue
But it is likely that someone who was infected could travel to the state, so it is something to take seriously,
Unlike native mosquitoes, Aedes aegypti bites mainly on the day, and it also only feeds on people and can't fly far – only about 500 feet – before it dies.
The discovery was announced on Tuesday at the York County Commission meeting, during a routine report by the regional director of health.
