Match the following types of infection with their definitions:

Endogenous infection = Caused by microorganisms normally present in the body Exogenous infection = Caused by microorganisms acquired from the environment Primary infection = Initial infection in a previously healthy individual Secondary infection = Occurs as a result of a primary infection weakening the immune system Signup and view all the answers

Match the following components of the chain of infection with their descriptions:

Infectious agent = The microorganism causing the infection Reservoir = The habitat in which the infectious agent lives, grows, and multiplies Portal of exit = The way the infectious agent leaves the reservoir Mode of transmission = The way the infectious agent is transferred to a susceptible host Signup and view all the answers

Age = Decreased immune response in the elderly Chronic illness = Weakening of the immune system Immunosuppressive medications = Reduced ability to fight off infections Malnutrition = Lowered resistance to infections Signup and view all the answers

Match the following infection control measures with their descriptions:

Hand hygiene = Critical in preventing the spread of infections in healthcare settings Standard precautions = Basic level of infection control that should be used for all patient care Personal protective equipment (PPE) = Includes gloves, gowns, masks, and eyewear to protect healthcare workers from exposure to infectious agents Environmental cleaning = Removal of infectious agents from the healthcare environment to prevent transmission Signup and view all the answers

Study Notes

Categories of Microorganisms

Four major categories of microorganisms causing human infections include bacteria, viruses, fungi, and parasites.
Commensal bacteria, which coexist with healthy humans, play a protective role against infections by outcompeting pathogenic organisms.

Pathogenic Bacteria

Pathogenic bacteria are characterized by their higher virulence, leading to disease and infections.

Baltimore Classification System

Developed by biologist David Baltimore, the Baltimore classification system categorizes viruses based on their type of genetic material and replication method.
The system includes groups such as ds (double-stranded) and ss (single-stranded) viruses.

Types of Infections

Various types of infections can be defined based on their etiology, such as bacterial, viral, fungal, and parasitic infections.

Chain of Infection Components

The chain of infection includes several components: the infectious agent, the reservoir, the portal of exit, the transmission mode, the portal of entry, and the susceptible host.

Risk Factors for Infection

Numerous risk factors affect susceptibility to infections, including age, immune status, preexisting health conditions, and environmental factors.

Infection Control Measures

Infection control measures are implemented to prevent the spread of infections; these can include hand hygiene, use of personal protective equipment, sterilization, and vaccination campaigns.
