HOUSTON (AP) - A new study says dengue fever, a mosquito-borne illness uncommon in the United States, has re-emerged in Houston.

The Houston Chronicle reports a study by the Baylor College of Medicine shows the virus has been transmitted in Houston, the first evidence the disease so prevalent in the developing world has spread to a major U.S. city in large numbers.

Dr. Kristy Murray, a professor of tropical medicine at Baylor and the study's principal investigator, says her team found that 47 of 3,768 individuals tested in Houston for West Nile virus from 2003 to 2005 were positive for antibodies to acute dengue infection. The study found two of the 47 died from the infection.

Murray says the cases suggest there was a dengue outbreak in 2003.
