Dengue virus identified in Houston

Murray's team investigated the possibility that dengue might be in Houston because the area has the type of mosquitoes known to carry the virus and a dense population full of frequent travelers south of the border, where the virus is endemic. But the study, published Wednesday in the journal Vector-Borne and Zoonotic Diseases, found that most of the infections were transmitted in Houston.

There is no vaccine or treatment for the virus.

A pandemic outside the United States - hot spots are in India and Bangladesh, Indonesia, Brazil and Mexico - dengue infects more than 100 million people a year, killing at least 25,000. Identified in nine tropical countries before 1970, it has spread to more than 100 today.
