Between May and September marks the season for a bug to come out in Texas, and it carries a disease-causing parasite that can become incurable. Between 16 million and 18 million people carry Chagas in Central and South America, and 50,000 of those infected will die each year. Nisha Jain Garg, a microbiology, immunology and pathology professor with UTMB, said treatment is generally only effective thus far in the early stages of infection, or shortly after bitten. Scientists are still in a discovery phase with regard to Chagas, Garg said. “I think we have more knowledge about the prevalence of Chagas in Texas,” Garg said. “There are more studies done now.”
