How does a person develop a communicable disease?
This may happen through: Once a pathogen has entered a person’s body, it will begin replicating. The individual may then begin to experience symptoms. Some symptoms are a direct result of the pathogen damaging the body’s cells.
How do communicable diseases spread?
The pathogens that cause these diseases can spread in various ways, such as through the air, contact with contaminated substances or surfaces, or from animal and insect bites.
What is the term for a disease that can be transmitted between people?
Communicable diseases can spread when people get close to each other. A communicable disease is any disease that passes between people or animals.
