Meanwhile, epidemiologic evidence often is the first basis for implicating a causative agent or mode of spread before the results of more in-depth and lengthier scientific investigations become available to support decision-making about interventions. Thank you for taking the time to confirm your preferences. For example, as indicated earlier in this chapter, excluding symptomatic employees and removing all possible existing sources of an enteric pathogen such as norovirus from a food preparation facility can be done regardless of the actual source of the outbreak (4).

If there is a partial or total breach in PPE (e.g., gloves separate from sleeves leaving exposed skin, a tear develops in an outer glove, a needlestick) during patient care, the healthcare worker must move immediately to the doffing area to assess the exposure and implement the facility exposure plan, if indicated. The sore is the location where syphilis entered your body. Accessibility StatementFor more information contact us atinfo@libretexts.orgor check out our status page at https://status.libretexts.org. In his seminal article on criteria for assessing causal associations in epidemiology, Austin Bradford Hill concluded with a call for basing action on weighing the strength of the epidemiologic evidence against the severity of the consequences of delaying action and of taking premature action (1). These sores usually occur in, on, or around the penis; The immediate action drills to take in the event of a high-risk exposure (needle stick injury and mucous membrane splash) should be clear to all healthcare workers.

These interventions are grouped according to those that can be directed at the source(s) of most infectious and other disease-causing agents and those that can be directed at persons susceptible to such agents. For example, during the 20162017 Zika virus infection outbreak, men returning from travel to epidemic areas were advised to use condoms when having sex with susceptible pregnant or potentially pregnant women, as well as for pregnant or potentially pregnant susceptible women to use condoms with any male partner who might have been exposed to the virus to decrease the womens risk for exposure (19). This section briefly addresses three such concerns. Each stage has different signs and symptoms. Lancet Infect Dis. Centers for Disease Control and Prevention.

For most outbreaks of acute disease, the scope of an investigation is dictated by the levels of certainty about (1) the etiology of the problem (e.g., the specific pathogen or toxic agent) and (2) the source or mode of spread (e.g., waterborne, airborne, or vectorborne) (3). https://www.cdc.gov/vhf/ebola/healthcare-us/ppe/guidance.html.
