A healthcare worker is a trained individual whose job description is focused primarily on providing care and health services to people who are sick and in need of treatment. They can work as doctors, nurses, or paramedics, but beyond these common roles, there are numerous other types of healthcare workers that are also highly influential within the field, such as personal support workers, laboratory technicians, pharmacists, dentists, sonographers, and many others.

It should be noted that some healthcare workers work in direct contact with patients and some of them don’t. This is the difference between frontline workers and other healthcare workers. Essential healthcare workers, on the other hand, fall under different criteria, as they are only considered "essential" when they deliver essential patient care and life-saving services. Good examples of these workers are nurses, physicians, care aides, pathologists, pharmacists, and others.

Regarding employment, healthcare workers are employed in a wide range of settings, such as nursing homes, hospitals, mental health facilities, primary care centers, dental clinics, and pharmacies; and their job descriptions are usually adapted to the common practices and needs of the patients that seek for health care in these different facilities.

According to multiple sources, there are approximately 60 million healthcare workers across the globe making a difference in people's lives. Their impact is so relevant that the World Health Organization (WHO) considers them as “the most valuable resource for health.”
