Cough into your cellphone and get diagnosed

Seattle: There may be a small change in etiquette a few months down the line. Cover your mouth with your cellphone , instead of your hand, when you cough; your mobile may be able to tell whether you have a cold, a flu, some other respiratory ailment, or if its just an irritated throat. 

A research company that proposes using acoustic vocalization analysis software to measure and interpret cough characteristic of pneumonia has won a $100,000 grant from the Bill and Melinda Gates Foundation, one of 76 projects named by the Foundation in its third funding round of its Grand Challenges Explorations.
The proposal is just one of several emerging ideas that could turn the cellphone into a medical diagnosis tool, eventually replacing a stethoscope (which may not be around to celebrate its bicentennial in 2016) and even becoming a personal scanner.
STAR Analytical Services two-page application on Using Acoustic Analysis of Cough to Diagnosis Pneumonia was one of 3,000 proposals the Foundation recognized as falling outside current scientific paradigms and having the potential to lead to significant advances in global health , criteria for winning the prestigious grant.
In their application, Stars researchers Suzanne Smith and Joel MacAuslan said analyzing distinctive cough sounds with new software (based on a pre-recorded data base of thousands of coughs of all kind of ailments from people of both sexes, all ages, and other variables), could lead to dramatic improvements in the management of respiratory illness in the developing world and interrupt epidemics far more rapidly.
For instance, such a tool could enable a mother in the distant African outback or Indian village without immediate mode or means of transportation to transmit the sound of her childs cough by cellphone to a city hospital, where a doctor checks this vital sign and determines the course of action. 

 
Cough is one of the most common symptoms of illness and a common mode of disease spread, yet we dont use technology in any way to measure or understand what coughs mean, Smith said, adding that for acute infections, measuring cough could become as familiar as recording temperature .
If the proposal leads to successful software tools, cough measurement may become one more vital sign available by phone. Already, researchers have been toying with mobile phones to monitor vital signs such as heart rate, blood pressure, body temperature and oxygen saturation readings. 

The cellphone is perfect because its like a wristwatch that you carry around, says Shankar Sastry, dean of engineering at the University of California, Berkeley, whose lab has dramatically advanced facial recognition algorithm. The obvious advantage with the cell phone he said was it can also can access and communicate information.
Eventually, experts are predicting that people will start to take control of health monitoring and maintenance , altering the dynamic of health care and changing the physician-patient relationship.
