Since 1928, the person responsible for the health care of US Presidents has been called the `White House physician`.

When Mr. Trump entered Walter Reed Military Hospital after testing positive for nCoV, Sean Conley, the White House doctor, became the center of attention.

Like his predecessors, Dr. Conley is responsible for protecting the President’s health and performing surgery in emergencies.

Mr. Conley graduated from the Philadelphia College of Osteopathic Medicine in 2006, according to records from the Medical Board of Virginia.

Dr. Conley also received a bachelor of science degree from the University of Notre Dame and served as an emergency physician for the US Navy.

Doctor Sean Conley spoke at a meeting at the White House, October 4.

In May, Dr. Conley attracted attention after supporting Mr. Trump to start using the malaria drug hydroxychloroquine to prevent nCoV, despite concerns from many experts.

But previously, the US Food and Drug Administration (FDA) warned that this drug should only be used in clinical trials or in hospitals.

Mr. Conley’s initial assessments after Trump was infected with nCoV also contradicted White House Chief of Staff Mark Meadows.

The role of Physician to the President has existed for more than 100 years, at least since 1898, when former President William McKinley hired Navy doctor Presley Rixey as his health officer.

White House doctors often make important decisions at times of emergency. In 1981, after former President Ronald Reagan was shot, Dr. Daniel A. Ruge confirmed that he needed surgery by the emergency team.

At other times, the position of `White House physician` became complicated by political interests.

The White House also has a separate medical unit, including leading doctors, responsible for `guarding` the health of many US Presidents since the 20th century. The White House doctor’s medical office is

In addition, political figures are cared for at Walter Reed Military Hospital in Maryland.

For many years, US Presidents have chosen Walter Reed as the medical examination and treatment location outside the White House.
