7/20/17 – A U-W Madison expert says a mosquito that’s capable of spreading the Zika virus should not be a cause for concern. State health officials say three bugs similar to the Asian tiger mosquito were found this week in the Madison suburb of Monona. It’s the first time a possible bug with the Zika virus has been found in Wisconsin — but there have been no human cases connected with the discovery. U-W entomologist P-J Liesch says the breed has been widely found throughout the southern U-S, and the only Zika cases were in Florida and Texas. Wisconsin has confirmed 67 Zika infections since it became known last year that the virus may cause birth defects in babies — but in all cases, patients contracted it while traveling abroad.
