What is an infectious disease infection?

Infection is the process of interaction between a pathogen and the human body. Pathogens invade the body, breaking through defense functions, growing and breeding, causing pathophysiological changes.

What is an infectious disease infection?

Types of
1. Primary infection, the first time the human body is infected with a certain pathogen. Some infectious diseases rarely re-infect, such as measles, chickenpox, and mumps.

2. Re-infection An infection in which the human body is again infected by the same pathogen on the basis of infection by a certain pathogen. Often referred to as schistosomiasis and hookworm disease.

3. Co-infection The human body is simultaneously infected with two or more pathogens. Less common.


4. Super infection The human body is infected by another pathogen on the basis of infection by a pathogen. More common clinical, such as chronic hepatitis B virus infection overlaps with hepatitis E virus infection.

5. Secondary infection In overlapping infections, other pathogen infections that occur after the primary infection. Such as viral hepatitis secondary to bacteria, fungal infections.
