- Adaptation of Immunoassays for Multiplexed Diagnosis of a Diverse Panel of Pathogens Associated With Acute Febrile Illness
This poster summarizes PATH’s recent activities as part of a consortium lead by the University of Washington to develop the DxBox, a system comprising a portable instrument and low-cost disposable cards. The prototype is being developed to diagnose typhoid fever, dengue fever, rickettsial diseases, malaria, measles, and influenza. PATH’s contributions are immunoassay development, field studies, and user needs assessment. Presented at The American Society of Tropical Medicine and Hygiene (ASTMH), November 12, 2006; Atlanta, GA.

- Addressing the Emerging Diabetes Epidemic in Low-Resource Settings
This fact sheet provides an overview of PATH’s efforts to develop evidence-based programs focused on diabetes prevention and control. Sixty percent of all deaths worldwide each year are due to chronic disease, mostly in low- and middle-income countries, where people develop the diseases at younger ages, suffer longer, and die earlier in life.

- An Advocacy Strategy for Adoption and Dissemination of the WHO Policy on TB Infection Control in Health Care Facilities, Congregate Settings, and Households
In 2010, the World Health Organization (WHO) issued a new policy to guide activities for controlling tuberculosis (TB) infection. This report provides guidance on advocacy for political and financial support for TB infection control from donors and countries, widespread adoption of the WHO policy, and incorporation of it into national and local policies. The report also addresses advocacy for linkages with civil society organizations in the field to ensure demand for and implementation of the WHO policy to protect health workers, patients, and communities from TB transmission.

- Affordable Point-of-Care Viral RNA Specimen Processing for Low-Resource Settings
PATH conducted a detailed cost analysis in Nicaragua to understand the costs of each step required to perform viral load testing, beginning at the patient’s house and continuing to when the viral load testing result is actually communicated back to the patient’s antiretroviral therapy care provider. Using this information, PATH has developed a low-cost technology to extract HIV viral RNA at the point of care and stabilize it, removing the need for cold chain preservation of the specimen.
