Injecting the flu vaccine into a tumor gets the immune system to attack it

Tuberculosis is still a rampant problem in the developing world. Doctors are looking for even more advanced ways to test for TB beyond the GeneXpert tests.

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.

Slow test results make it difficult to stop the spread of tuberculosis. Using faster diagnostic technology and driving vans to rural areas in Tanzania, GeneXpert is making progress in treating this curable disease.

PrePex, a new nonsurgical circumcision tool, could revolutionize the prevention of H.I.V. and AIDS in sub-Saharan Africa. Cheap and easy to assemble, the device has proven successful in several randomized trials.

The Jaipur Limb organization based in India has developed prostheses at low cost, and services are free for the poor. The organization’s efforts have recently spread to other countries with impoverished people. Jaipur Limb reaches patients through branch clinics, traveling workshops, and limb camps in cities around the world.

A prosthetist from Texas visiting Jaipur Limb workshops in Honduras saw problems with their low-cost prosthetics - the issue wasn't the design of the leg, but the technicians at the Honduras workshops were people completely new to prosthetics who were given just eight weeks of training. Thanks to his research, Jaipur established a research and development unit to improve the limb.

An estimated 6,000 "never events" — egregious errors like operations on the wrong limb or instruments left inside a surgical wound — occur every month among Medicare patients alone. Hospitals across the country are revamping their care programs to stop preventable injuries and deaths.

After ongoing trials and successes for preventative measures toward malaria, experts have now reversed their support for them. In what remains an ongoing threat, especially to children, new interventions, like the combination of multiple malaria drugs, are being tried, tested, and showing promise.

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.

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.
