    • Endemic diseases are regularly found in certain areas, such as Ebola
    • Disease prevention measures include sewage treatment, water purification, pasteurization, and vaccination
    • Infectious diseases are caused by pathogens and can be identified based on their local or systemic impact
    • Communicable diseases spread from person to person, while opportunistic infections occur when the host's immune system is suppressed
    • The chain of infection describes the spread of infection in the population and involves components such as infectious agents, reservoirs, and modes of transmission
    • Infection control measures include standard precautions, OSHA regulations, handwashing, antiseptics, and disinfectants
    • Antibiotic resistance is a growing concern due to factors such as overuse, misuse, and transfer from animals to humans
    • Medical asepsis reduces the number of pathogens, while surgical asepsis removes all pathogens and microorganisms
    • The body's natural defense against disease involves first, second, and third lines of defense, influenced by factors such as age, trauma, illness, and nutritional status
