Endemic Chagas disease has emerged as an important health disparity in the Americas. As a result, we face a situation in both Latin America and the US that bears a resemblance to the early years of the HIV/AIDS pandemic. Neglected tropical diseases (NTDs) are among the most common conditions afflicting the estimated 99 million people who live on less than(More)
BACKGROUND The Routine Universal Screening for HIV program provides opt-out HIV testing and linkage to care for emergency department (ED) patients in Harris Health System, Houston, TX.

In June 2006, a human case of domestically transmitted T. cruzi was identified in southern Louisiana. To examine the localized risk of human T. cruzi infection in the area surrounding the initial human case, environmental surveys(More)

Many health departments also have limited access to outside academic expertise. METHODS We conducted a survey of health organizations in the Houston/Harris County region to determine the number of HIV tests completed in(More)

As many as 40-50% of persons living with HIV (PLWH) who once were in HIV care are no longer in care. It is estimated that these individuals account for over 60% of HIV transmissions. So, preventing the leaving of care and re-engaging PLWH with care are crucial if the HIV epidemic is to be brought under control. Clinicians can improve retention by keeping in(More)
BACKGROUND Although funding has supported the scale up of routine, opt-out HIV testing in the US, variance in implementation mechanisms and barriers in high-burden jurisdictions remains unknown. METHODS We conducted a survey of health care organizations in Washington, DC and Houston/Harris County to determine number of HIV tests completed in 2011, policy(More)
