In rural communities around the world, the virtual doctor is in.

The distance between far-flung communities and their nearest hospitals can be fatal. Medic Mobile bridges the gap using a common household item: the cell phone. It’s not the same as a living, breathing doctor, but Medic Mobile comes pretty close, and it does so using a list of platforms that is strikingly similar to what you might find on a smart phone. These seemingly-sophisticated technologies can work on even the most basic of cell phones and computers, just like those found all over the developing world.

Medic Mobile’s Sim Apps, in addition to open-source platforms like FrontlineSMS, OpenMRS, Ushahidi, Google Apps, and HealthMap, allow hospital staff sitting at a computer to communicate with multiple health workers in rural areas. The health workers’ phones are basic, but Medic Mobile uses a tiny parallel SIM card that fits between any GSM phone and a carrier’s cell phone to allow these phones to run the necessary apps. The Medic Mobile website provides a more in-depth description of the many technologies it employs. In a 2009 interview with GOOD magazine, co-founder Lucky Gunasekara described Medic Mobile’s importance:

We can communicate need in real time. Say I am a community health worker in rural Malawi and one of my patients gets really sick. Before this system came along, for a lot of clinics, the patient would die, because even though I have some basic health training as a community health worker, there is nothing I can really do. They're still just as disconnected as the communities they live in. Now with our system clinicians see things in real time and they communicate back.

In addition to saving lives, the program saves time: its website says that in six months, the pilot program in Malawi “saved hospital staff 1200 hours of follow-up time and over $3,000 in motorbike fuel” and cut 900 hours of travel time for antiretroviral therapy monitors by eliminating their need to hand-deliver reports to the hospital.

Since its inception in 2009, Medic Mobile has expanded to Honduras, Haiti, Uganda, Mali, Kenya, South Africa, Cameroon, India and Bangladesh. The platform is adaptable to different situations: it was used in Haiti following the 2010 earthquake to link first responders and locals in need of help. As a result of its successes, Medic Mobile was recently named one of the Top 11 in 2011 mobile health innovators of the year by mHealth Alliance.

The proliferation of cell phones is sparking a revolution in developing-world health care. Innovators from all reaches of the globe have used the near-ubiquitous technology to increase health care affordability and access. By adapting sophisticated platforms to basic devices, they’re turning $15 cell phones into invaluable lifelines.

A team of engineers at the University of California at Berkeley are pushing the limits of cell phone technology with the development of their newly minted Cellscope.

The device is a six-inch microscope that attaches to a cell phone’s digital camera lens to take high resolution microscopic images of blood and sputum samples. The Cellscope's compact size and durability makes it ideal for use in the field, nearly eliminating the health worker's need for expensive tabletop microscopes.

The Cellscope team, led by Principal Investigator Dan Fletcher, has been able to reliably identify pathogens from two of the most prominent diseases in the underdeveloped world — malaria and tuberculosis. Combined, the World Health Organization estimates that the two diseases kill 2.7 million people each year, although both are treatable if caught early. (The vast majority of malaria and tuberculosis cases are found in sub-Saharan Africa and Asia respectively.) The Cellscope offers healthcare workers in remote areas a valuable diagnostic tool, aiding in reliable early detection of these two diseases.

Right now the Cellscope is still being tested in the field. But the UC Berkeley team hopes that in time, data captured by the Cellscope will be uploaded to a central database, allowing medical workers to track the spread of diseases more efficiently than ever before.

Sure, your cell phone can take pictures and send text messages, but can it detect malaria?

UCLA scientists have found a way to bring medical diagnostic tests to resource-poor areas by transforming cell phones into cheap, portable gadgets that can monitor and detect diseases like malaria and HIV.

As Wired explains:

UCLA researcher Dr. Aydogan Ozcan images thousands of blood cells instantly by placing them on an off-the-shelf camera sensor and lighting them with a filtered-light source (coherent light, for you science buffs). The filtered light exposes distinctive qualities of the cells, which are then interpreted by Ozcan's custom software. By analyzing the cell types present in a much larger sample, a more accurate diagnosis can be made in a matter of minutes.

Currently, the software to analyze these images runs on a desktop computer, but Ozcan’s team is working to create software that runs on the cell phone device itself.

This technology is still in developmental stages, and skeptics are already lighting up online discussion boards. But the promise of quick, accurate and low-cost blood testing in the world's most remote areas is definitely exciting. And if this idea does become a widespread reality, here’s hoping that effective treatment for those diagnosed follows quickly on its heels.
