3. list three pioneers in the field of infection control

Ignaz Semmelweis, Louis Pasteur, and Joseph Lister.

Explanation:

Ignaz Semmelweis is a Hungarian physician who tried to implement a handwashing system in Vienna hospitals in the 1840s to reduce maternity mortality rates. He became known as the savior of mothers. As you may already know, hand washing is essential in the medical environment because it prevents very dangerous cases of nosocomial infection. The handwashing habit created by Semmelweis is still used today and has saved many lives.

Louis Pasteur, born in 1822 in Dole, France, was a chemist who revolutionized infection control methods. His scientific discoveries had a huge impact on medicine, and his work began what we now call microbiology. Pasteur's importance from a theoretical point of view is remarkable, as he answered important questions about the cycle of life and death in nature by considering the phenomena of fermentation and putrefaction. It was he who created pasteurization which is a very important asception method to this day.

Joseph Lister is named after the introduction of surgical asepsis. He graduated in 1852 from University College in London and for several years practiced medicine in Edinburgh. In 1860 he assumed the chair of surgery at the University of Glasgow and in 1869 at Edinburgh. By the time he was working in Edinburgh, Lister had already introduced the technique of chemical asepsis, significantly reducing postoperative deaths.
