To date, there have been eight attempts to eliminate polio, along with a score of other infectious diseases around the world, but only the elimination of smallpox has been successful. Using modern day smartphone and satellite technology, however, the World Health Organization (WHO) can better locate remote areas where polio is still a threat.

Polio has been eradicated in all but three countries: Nigeria, Afghanistan and Pakistan. The disease is spread by direct person-to-person contact, as well as indirect contact. Insecurity, poor health care and lack of proper sanitation are all reasons as to why these countries still struggle with a preventable disease that is only a distant memory to many countries around the world.

Polio is an disease that can lead to paralysis and even death if not treated. Unfortunately, there is no cure for polio once the infection takes hold, only treatment to make living with it more bearable. However, 100 percent of cases are preventable if every child under the age of five receives a vaccination. In countries like the U.S., the polio vaccine is mandatory.

In order to locate remote communities in Nigeria, Afghanistan and Pakistan, WHO workers use geographic information systems (GIS). GIS involves transmitting satellite images to a computer in order to map an area. In the past—as little as ten years ago—those who wanted to map an area of land would have to fly over it and take pictures. GIS is an improvement on this, as it is remote and allows for more land to be mapped more quickly.

By using GIS, those at WHO can determine the location of extremely rural villages where children need to be vaccinated for the first time, or maybe even the fourth or fifth time, as certain remaining strains of polio are stronger and require multiple vaccinations.

This technology can also be connected to WHO members’ smartphones and allow the organization to track the location of employees, volunteers and patients. This has allowed for an increase in the number of vaccinations, as well as better supervision on the part of the WHO. It is extremely difficult for volunteers to slack off or lie when the operation is being monitored so closely.

Before this collaboration of satellite imaging and smartphones, it was extremely difficult to know which households had been vaccinated and educated on polio prevention and which had not. But since 1988, polio has been reduced by 99 percent, with cases down from more than 350,000 a year to only 406 in 2013.

However, 99 percent is not 100 percent. Technology and dedication may not be enough to completely eradicate the disease, as distrust of western medicine instigated by propaganda from groups such as the Taliban have made it difficult for workers to administer the vaccine.
