A Virtual Health Assistant (VHA) is a computer-based tool that helps patients and healthcare providers by performing routine tasks. It’s powered by artificial intelligence and can understand and respond to people in a natural way—either through chat or voice.

Unlike simple chatbots, virtual health assistants are designed specifically for healthcare settings. They can do many things, like answering health-related questions, reminding patients to take their medication, helping with appointment booking, collecting patient feedback, and even supporting mental health. These assistants are trained to understand medical language and respond in a helpful and professional way.
