Diseases can be spread sexually (kissing, sharing bodily fluids etc), airborne(when you cough or sneeze into the air), physical contact (germs on your hands, skin diseases, etc). Diseases can be spread in many ways.
The key points of the germ theory of disease are that microorganisms (germs) are responsible for causing infectious diseases, these microorganisms can be spread from person to person, and that proper hygiene and sanitation practices can prevent the spread of these diseases.
Germs can be spread b close conact with a person who has the germ.
Germs that spread from person to person to cause diseases are contagions.People who are then infected with the germ, only during the active phase of the germ's "life", are then referred to as being contagious.

Infectious diseases are spread through various means such as direct contact with an infected person, respiratory droplets when someone coughs or sneezes, ingesting contaminated food or water, or through vectors like mosquitoes or ticks. Some infectious diseases can also be spread through blood or bodily fluids.

Germ theory refers to the concept that infectious diseases are caused by microorganisms, such as bacteria, viruses, and fungi, rather than by supernatural forces or imbalances in the body. This theory revolutionized the understanding of how diseases spread and led to advancements in public health practices, such as sanitation and sterilization measures.
The germ theory of disease was developed by scientists in the 19th century, notably Louis Pasteur and Robert Koch. They conducted experiments that showed that microorganisms, or germs, were responsible for causing infectious diseases. This discovery revolutionized our understanding of how diseases spread and led to improved hygiene and medical practices.
contagious diseases speared in many ways while anybody is eating the bacteria spread in air while coughing the bacteria enter in to air the bacteria goes to another person like these the contagious diseases spread
noninfectious diseases dont "spread" as they are "caused by either the environment, nutritional deficiencies, lifestyle choices, or genetic inheritances. Unlike infectious diseases, non-infectious diseases cannot be spread from person to person, although some kinds can be passed down genetically to the children of a carrier."
There are Infectious Diseases and Non infectious Diseases. Infectious diseases can be transmitted from person to person, and can be spread from one living thing to another are known as communicable diseases. They can be caused by, Bacteria, Viruses, Protists, etc. which is the Plague. Non infectious diseases can not be transmitted from person to person, these are things like Cancers.
