    Study Notes

    Infection Control Measures and Disease Prevention

    • 1 in 9 women in Long Island will develop breast cancer
    • Mortality rate measures the percentage of the population that dies 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
    • Pandemic is 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 disease is caused by a pathogen, and infection means that the pathogen is living in the human body, multiplying, and causing symptoms
    • The chain of infection describes the spread of infection in the population and includes components like infectious agent, virulence, number, reservoir, portal of exit, mode of transmission, portal of entry, and susceptible host
    • Infection control measures include standard precautions, OSHA requirements, handwashing, antiseptics, disinfectants, antibiotics, and natural defense against disease
    • Antibiotic resistance is a growing concern due to factors like overuse, misuse, and transfer from animals to humans
    • Medical asepsis reduces the possible number of pathogens, while surgical asepsis removes all pathogens and microorganisms
    • The natural defense against disease includes the first line, second line, and third line of defense, and factors like age, trauma, illness, general state of health, comorbidity, nutritional status, fatigue, stress, and invasive therapy can influence infection
    • Titers are antibody levels in the body and indicate the level of antibodies present
