Mosquito That Carries Dengue Virus And Yellow Fever Virus Discovered In California

I teach Virology and Advanced Virology courses at the University and I found this news article interesting.  The mosquito that carries various viruses including Dengue virus and Yellow Fever virus has been discovered in California.  Presently, we have a vaccine for Yellow Fever (17D), but none for Dengue virus.  http://www.ibtimes.com/yellow-fever-mosquito-aedes-aegypti-found-california-very-difficult-control-1433136
