Washing hands in between contact with patients is one of the most important things a healthcare worker can do to prevent the spread of disease and reduce the rise of superbugs like MRSA. A new technology is increasing rates of hand washing by displaying, via a sensor in an employee's badge, whether the healthcare provider has washed their hands recently.

In the developing world, intestinal worms stunt physical and mental growth, drain energy, and can inhibit school work for children. Deworm the World is a global campaign that lobbied the Delhi government to regularly distribute deworming pills to school children. The benefits decrease student absenteeism and increase cost-saving measures.

A cholera epidemic can kill many people or few people—it all depends on the expertise of the doctors and their access to the right equipment. A program in Dhaka rushes both to countries when an epidemic is just breaking out.

India has, for years, been a hotbed of polio. Supported by the WHO as well as local health-care workers, immunizations have officially rid the country of the disease. There are still challenges in maintaining records and reaching everyone, but the message continously changes and adapts.
