Dengue Fever PredictionThe ability to determine where and when epidemics will break out may soon be available at the touch of your fingertips.

In Pakistan, dengue fever was largely endemic in the southern city of Karachi; however, in recent years it has been appearing in a previously unaffected area — northeast Pakistan.

The World Health Organization (WHO) states that dengue fever is transmitted by the infectious bite of a mosquito, and currently there is no vaccine or specific medication for this illness, which usually results in a range of symptoms including “mild fever, to incapacitating high fever, with severe headache, pain behind the eyes, muscle and joint pain and rash.”

A recent article by SciDev describes the possibilities of a mobile phone app which can effectively predict epidemics by tracking the patterns of people.

“As the transmission of the virus that causes dengue fever is partly driven by human travel, analyzing how people move across the country allows researchers to predict when and where epidemics may break out,” SciDev says.

Telenor, a Norwegian mobile provider that operates in Pakistan, teamed up with researchers to track the call records from close to 40 million subscriber SIM cards within the last seven months of 2013.

Mathematical data pertaining to traveling patterns could be tracked and was later published in Proceedings of the National Academy of Sciences.

This information combined with clinical and climate data helped serve as a “model retroactively to predict the likely location and timing of epidemics across the country.”

This newfound data provided encouraging results that would enable researchers to “effectively target interventions, surveillance and clinical response” for where and when to expect dengue epidemics.

“The travel model predicted the geographic spread and timing of outbreaks in 2013 in both recently epidemic and emerging locations, the paper says. For example, it showed good overlap with the actual pattern of the first dengue cases in the northeastern cities of Lahore and Mingora,” says SciDev.

Predictive models may be the solution for mapping and creating early warning systems for diseases such as dengue. With such success regarding Dengue Fever prediction in Pakistan, it is possible for other Asian countries to adopt the same technology for other diseases, such as measles, malaria and influenza.

Soon, the very touch of a button may be able to save thousands from experiencing the disease via dengue fever prediction.

According to the US Environmental Protection Agency, ranking behind paper, food is the second largest source of waste.

Twenty-five-year-old Komal Ahmad, who graduated from the University of California at Berkley in 2012, is solving this problem by feeding millions of people with her phone app, Feeding Forward.

In 2011, Ahmad was approached by a homeless man who asked her for money. Instead of cash, Ahmad offered to take him to lunch. As they ate, she discovered he was a returned soldier who, after some bad luck, now made his living begging on the streets.

Ahmad was overwhelmed by his situation. Determined to help others like him, she started a program at UC Berkley where cafeterias donated excess food to homeless shelters. Soon after, the program expanded to 140 colleges across the United States.

But Ahmad didn’t stop with the food recovery program.

“Imagine a football stadium filled to its brim,” Ahmad says. “That’s how much food goes wasted every single day in America.”

In 2012, Ahmad collaborated with a developer and they launched the Feeding Forward mobile app in 2013. The app originally targeted restaurant owners and event planners in San Francisco who could use the app to donate leftover food to homeless shelters. By entering their location into the app, a Feeding Forward driver picks up the leftover food and delivers it to shelters in the area.

In addition to the app, Feeding Forward has its own website.

Since Feeding Forward launched, Ahmad has recovered more than 691,896 pounds of food, which fed more than 570,000 people.

Now the CEO of her nonprofit organization, Feeding Forward, Ahmad says, “We need to figure out how to establish sustainable solutions that can distribute the food we already have faster and get it to people who need it faster and safely.”

Ahmad’s mobile app is proof that quick and successful distribution can feed the hungry.

In early June 2015, Feeding Forward partnered with the Bite Silicon Food Valley food-tech conference in Santa Clara, California. Over the course of three days, celebrity chefs prepared a wide range of meals. After the event, Feeding Forward collected 5,135 pounds of food which fed more than 4,279 people in eight different homeless shelters.

Around the world, the Feeding Forward app is praised and desired.

“I didn’t expect it to blow up,” Ahmad says. “People as far as Nairobi, Bangalore and Hong Kong have wrote us asking us to expand Feeding Forward to their cities and countries. They’re like, ‘Tell me what I can do to get it here.’”

The mobile app is currently being revamped. It will be available again in August 2015. The website, however, is still up and running.

Feeding Forward offers hope for other countries struggling with hunger and food distribution.

Ahmad says, “These are huge cities that have absurd amounts of food thrown away every day. We are trying to make the Bay Area a case study to say ‘Hey, if it works here, it can work anywhere.’”
