Answer:
In pure medical terms, an infection is the invasion and multiplication of a microbial agent in a human or living body. So, infectious disease means the illness and the deterioration in health which is caused by pathogens. When these microbial agents do not cause any harm to the health, it is referred to as subclinical infection. However, when they do affect the health, the condition is called infectious disease. Most of the infectious diseases (not all) are contagious. This means that they can spread from one person to another.
As mentioned earlier, most of the infectious diseases are contagious. They are easily and quickly spread. When an infected person comes in contact directly or indirectly with a healthy or an uninfected person, these pathogens are transmitted to a new host body. In the new host they replicate and cause the same infectious disease as they did in their previous case. There are many ways in which they are transmitted and spread from one body to another. Have a look at the list below and read how are infectious diseases spread:
The main ways in which infectious diseases are usually spread are enlisted as follows:
They are spread through air.
From any kind of contact either direct or indirect between an infected and an unaffected person.
Saliva of the infected person/animal.
Blood or other bodily fluids.
Skin or mucous membrane in the body (Nose, mouth, genitals etc.)
By consuming contaminated food or water.
Urine or feces carrying infections.
Soiled, dirty and unhygienic objects.
Carried through sexual contact between partners.
eg:-
Air borne Pathogens:
Some pathogens are carried through the air particles. When an infected person coughs or sneezes, the pathogens are released into the air. These can be inhaled by another person and make them sick. The main diseases that are spread by air include chicken pox, common cold, diphtheria, flu, measles, meningitis, mumps, rubella, strep throat and tuberculosis, etc.
