Over 100 years ago, an Austrian psychiatrist cured patients of neurosyphilis by infecting them with malaria. The malaria caused a fever that triggered the patients’ immune responses against their neurosyphilis.

Patients don’t necessarily need to suffer fever, though, to stimulate their immune response. The elevation of their body temperature alone can achieve this effect.

Which key antiviral protein is mobilized when body temperature is raised? How can this be safely done to combat infections like COVID-19?

On Vital Signs with Brendon Fallon, Dr. Roger Seheult highlights past and present methods used to escalate “virus-blocker” interferon proteins in the body.

Dr. Seheult worked as a critical care physician in an intensive care setting during the pandemic. He oversaw the use of hydrotherapy to stimulate patients’ interferon response against Coronavirus infection.

Interferon is “effective against multiple variants, in fact, all the variants of COVID-19 … It’s a very broad tool that our body has … to battle foreign invaders, especially viruses,” says Dr. Seheult.

Although lacking modern medical technology, American sanitariums still effectively treated patients during the 1918–1920 flu pandemic. What do their methods tell us about how to counter viral infection today?

Dr. Seheult is quadruple board-certified in internal medicine, pulmonary diseases, critical care medicine, and sleep medicine. He is an associate clinical professor of medicine at the University of California.
