Ashenafi Tazebew of the University of Gondar in Ethiopia will develop a training and supervision program whereby medical and nursing staff working at local health science colleges in Ethiopia are trained to teach and mentor local health care workers to improve their skills, and the quality and safety of immunizations, thereby increasing uptake. They will develop supervisory and mentorship guidelines and tools, and train college workers how to coach primary health care providers and review their performances.

Amadou Alpha Sall of Institut Pasteur de Dakar in Senegal will add quantum dots to liquid patient samples for better tracking of results and to store diverse types of information relevant for diagnostics and research that can be retrieved in real-time. They will tag samples using stable semiconductor quantum dots to generate unique signatures that can be read by a mobile-based, lens-free, fluorescence microscope.

Jerome Ateudjieu of Meillerur Acces aux Soins de Sante in Cameroon will test whether training community volunteers to record demographic movements and monitor births and immunizations of residents and visitors in their villages can improve timely childhood vaccination coverage in Cameroon. Many health districts in Cameroon have reported outbreaks of vaccine-preventable diseases.

Gerard Cangelosi of the University of Washington in the U.S. will develop reagents to visually validate oral swabs and stabilize them for storage and transport to diagnostic laboratories in low-resource settings without the need for a cold chain. Oral swabbing to extract saliva is a non-invasive and effective method for diagnosing tuberculosis, and is faster and safer than traditional sputum collection. However, it is more difficult to review the quality of a swab sample as they are hard to see, and processing currently requires refrigeration.

Xing Xie of the Georgia Institute of Technology in the U.S. will test whether super-absorbent polymers in sample tubes can improve the accuracy of diagnostics by absorbing molecules like DNA and viruses from liquid samples such as blood, and protecting them during transport to the laboratory. Normally, blood and urine samples degrade over time, particularly when they are exposed to heat or cold. This makes the subsequent diagnostic result unreliable.

Tara Hopkins of Mali Health in the U.S. will develop methods to improve vaccination coverage in rural communities in southern Mali by engaging community health workers together with traditional birth attendants who are present during home births. In southern Mali, particularly in rural communities, most children are born at home, so they are not registered with a health clinic or present for critical childhood vaccinations.

Pushpendra Singh of IIIT Delhi in India will develop interactive training and mentoring sessions for community health workers in India (ASHAs) using mobile phones and interactive voice response systems so they can provide better public healthcare in rural communities. Current training programs are run by medical professionals and require the workers to visit a health center, which may be inconvenient. The lack of medical experts has also reduced the frequency of these programs.

Günther Fink of the Swiss Tropical and Public Health Institute in Switzerland will develop a mobile phone-based system to improve the registration of births and the timeliness of childhood vaccinations in Ghana. Particularly in Northern Ghana, many women give birth at home and are less likely to ensure their infants get vaccinated on time, which exposes them to severe infectious diseases such as polio. Even in these low-resource settings, mobile phones are common, and have been successfully used to encourage healthy behavior.

Apostolos Alissandratos of the Australian National University in Australia will develop a biotechnology platform for the low-cost production of simple, just-add-water diagnostic tests for the early detection of infectious diseases in resource-limited settings. Diagnosis of infectious diseases generally involves detecting pathogen-specific nucleic acids in human samples, which requires unstable reagents, costly procedures, and skilled workers. They have engineered a safe bacterium that produces the biochemical reagents needed to detect the pathogenic nucleic acids as an extract.
