chain of infection Continuous link through three primary elements: reservoir, mode of transmission, and susceptible host.
common vehicle transmission Common source that causes multiple case of disease. contaminated items, food, water, meds, etc.
contact precautions used for patients known or suspected of having diseases or conditions transmitted by direct contact or with items in the environment.
contact transmission most frequent and important transmission route for HAIs. direct contact transfers microorganisms.

respiratory hygiene/cough etiquette Covering your mouth when you cough.
sepsis a life-threatening medical emergency where the body has an extreme, overactive response to an infection, damaging its own tissues and organs.
standard precautions Infection control measures that use barrier protection and work practice controls to prevent contact between skin or mucous membranes and blood, other body fluids, and tissues from all people.
transmission-based precautions This tier is targeted at patients known or suspected of being infected with a highly transmissible pathogen.
vectors infectious agents are carried by agents such as arthropods(insects and ticks) that are not harmed by their presence.
