Being able to find high quality health care at an affordable price is an issue in many countries. In the United States, Walmart, a large chain store, is trying to help. It is offering something new to its employees: cutting the cost of a doctor’s appointment to only $4. The Associated Press news agency notes that Walmart once required its employees to pay $40 for the same service. Why is the price so low, you might ask? What’s the catch? The catch is that the patient and doctor must meet electronically; over the internet. This online service is called “telemedicine.” Walmart is the latest major business in the United States to push its workers toward a high-tech way to be examined and treated by doctors. Thanks to telemedicine, people can talk with medical experts from the privacy of their own homes, often using a secure video connection. Many in the U.S. healthcare industry see this as a good time to teach people how telemedicine services can help them.
