outbreak an discovered have to S.state ．Usecond the become has Hawaii

locally acquired Dengue Fever (登革热)．Florida has been combating its own local outbreak since September 2009.The Hawaii Department of Health reported on March 24 it had discovered two cases and suspected two more.Since then, KGMB(a television station for the state of Hawaii)reports four confirmed and 12 suspected cases.Florida saw 85 locally acquired cases in 2009 and 2010.

Dengue Fever and its far more serious variant(变种)，dengue hemorrhagic(出血

的)fever, are transmitted from patient to patient by the bite of a mosquito.It is reported that the Asian Tiger mosquito and the Yellow Fever mosquito are the two primary carriers for the illness in the United States.Both mosquitoes are highly adapted to living around humans and are day feeders.The Asian Tiger mosquito has even evolved into a slower rate of beating its wings, which reduces the whine or hum typically noticed by people when mosquitoes are near.

The Hawaii outbreak is centered around Pearl City on the island of Oahu.The Florida outbreak has been confined to the Key West area with one case in Broward County and another in Miami-Dade.

Dengue is caused by one of four related viruses.There is a vaccine for one of the four.It is possible to catch each of the viruses since infection with one does not produce immunity for the others.It appears that initial infection, or the injection of the dengue vaccine, makes the patient significantly more susceptible (易受感染的) to dengue hemorrhagic fever.
