What is the primary difference between medical asepsis and surgical asepsis?
Medical asepsis aims to reduce the number of pathogens, while surgical asepsis aims to eliminate all pathogens.
What is the significance of antibiotic resistance?
It is primarily due to factors such as overuse, misuse, and use in animal feeds.

Due to factors such as overuse, misuse, and use in animal feeds
Study Notes
Infection Control and Disease Prevention Measures
- 1 in 9 women in Long Island will develop breast cancer
- Mortality rate is the percentage of the population that die due to a disease within a specific period of time
- Epidemic refers to the widespread occurrence of an infectious disease in a community at the same time, while pandemic refers to an epidemic over a large geographical area affecting a large portion of the population
- Disease prevention measures include sewage treatment, water purification, pasteurization, and vaccination
- Infectious diseases are caused by pathogens, and infections are identified based on their local or systemic extent
- Communicable diseases spread from person to person, and opportunistic infections occur when the host's immune system is suppressed
- The chain of infection describes the spread of infection in the population and includes components such as the infectious agent, reservoir, portal of exit, mode of transmission, portal of entry, and susceptible host
- Infection control measures include standard precautions, handwashing, use of antiseptics and disinfectants, antibiotics, antivirals, and antifungals
- Antibiotic resistance is a significant issue due to factors such as overuse, misuse, and use in animal feeds
- Sterilization kills all microorganisms on an infected instrument, including spores
- Medical asepsis involves reducing the possible number of pathogens, while surgical asepsis involves removing all pathogens and microorganisms
- The body's natural defense against disease includes the first line (intact skin and mucous membranes), second line (nonspecific ways to kill pathogens), and third line (specific means involving antibodies) of defense, as well as immunosuppression.
