DALLAS (AP) - Texas has recorded 25 cases of dengue fever since July, including the only cases of the tropical disease acquired in the U.S. this year, health officials said. At least five cases were acquired in the U.S., while some were believed caught in Mexico and Brazil. Others are still being investigated. It's the state's largest outbreak since 1995, when 29 people caught the disease, seven acquired in the state, the officials said Tuesday. Texas is the only state that has reported locally acquired cases of the virus in the last 50 years, said Vance Vorndam, a microbiologist for the U.S. Centers for Disease Control and Prevention. Although diseases like dengue, yellow fever and malaria were common in the U.S. earlier this century, they have been mostly wiped out.
