What diseases are not yet to find a cure?
There are still some diseases such as HIV/AIDS that scientists are yet to find a cure for in the health sector. Our food and liquids are safer than ever because Pasteur discovered pasteurization, which made it safer for people to consume as there were very few harmful microbes left. A new form of pasteurization has been discovered by using similar methods, only done different ways.
Joseph Lister is known as the ‘Father of Antiseptic Surgery’ and introduced principles of cleanliness into hospitals which transformed surgical practice in the 1800s. Lister understood that many people survived medical operations but could not understand why many caught ‘ward fever’ and died after the procedures. In 1860, Lister read the work of Louis Pasteur on how wine was soiled. Lister decided to experiment with one of Pasteur’s techniques – exposing a fresh wound to chemicals.
Lister had previously heard about the work of a Hungarian doctor called Ignaz Semmelweiss who argued that if a doctor went from one patient to another without cleaning their hands after surgery, then they would pass on diseases and help them spread, (Glasgowguide.co.uk, 2015). Semmelweiss argued that doctors must wash their hands in calcium chloride after doing an operation and before visiting a new patient.
