Let’s learn more about the Germ Theory!

• Germ Theory is currently the most widely accepted scientific theory for many diseases across the globe. It simply states that microorganisms known as pathogens or “germs”, which exist in various conditions, can lead to disease. It has roots in the Middle Ages era.
• However, it really increased in prominence throughout the 19th and 20th centuries when industrialisation led to a rapid increase in the level of germs surrounding people at home and those at work. It took off with the study of numerous widespread diseases common in the 19th century including most prominently tuberculosis and cholera. The scientist most credited with the disease is Dr John Snow, who was the first to make a scientific link between water pollution and cholera epidemics in Victorian London and Louis Pasteur who would prove it in France.
• Apart from Louis Pasteur, several European researchers were particularly c

  Germ theory of disease

  Prevailing theory about diseases

  The germ theory of disease is the currently accepted scientific theory for many diseases. It states that microorganisms known as pathogens or "germs" can cause disease. These small organisms, which are too small to be seen without magnification, invade animals, plants, and even bacteria. Their growth and reproduction within their hosts can cause disease. "Germ" refers not just to bacteria but to any type of microorganism, such as protists or fungi, or other pathogens, including parasites, viruses, prions, or viroids.^[1] Diseases caused by pathogens are called infectious diseases. Even when a pathogen is the principal cause of a disease, environmental and hereditary factors often influence the severity of the disease, and whether a potential host individual becomes infected when exposed to the pathogen. Pathogens are disease-causing agents that can resehandling from one individual to another, across multiple domains of

Germ theory of disease facts for kids

The Germ theory of disease is a theory in biology. It says that small organisms (called germs), also known as microbes, cause some diseases. These diseases are called infectious diseases. The germ theory states that small organisms cause a reaction in the body of those who are infected. The body's reaction to infection is called a disease.

Many scientists and doctors in history figured out that diseases are caused by microscopic organisms. Even after the microscope was invented, people still didn't know that germs caused diseases. People long believed that "bad air" from stinky trash dumps and from rotting meat was the cause of diseases. So people thought that covering their mouth and nose with a cloth would help filter out the "bad air." Scientists and doctors would use garlic and perfumes to ward off the bad air. But people still got sick and even died, so this theory was wrong. Polluted air is not the c
