Assessing causality at each step in an investigation is important not only for assessing the strength of evidence developed up to that point, but also in helping to identify what evidence is missing or requires further attention and for planning additional approaches (e.g., data gathering and analysis) essential for supporting decisions regarding interventions. Read the list of the three levels of prevention again. Each of the three approaches has an important role to play in disease prevention. [211]Wong KK, Davey RT Jr, Hewlett AL, et al. Health information and warnings about tobacco use This section examines three highly interrelated key determinants: severity of the problem, levels of certainty about key epidemiologic factors, and causation criteria.

It is a live attenuated vaccine which contains vesicular stomatitis virus that has been modified to contain a protein from the Zaire ebolavirus. A two-dose vaccine regimen of a different vaccine that was also designed to protect against the Zaire ebolavirus species of Ebola was used under a research protocol in 2019 during an Ebola outbreak in the Democratic Republic of the Congo.

[82]Centers for Disease Control and Prevention. The first categoryinterventions directed at the sourceincludes measures that would eliminate the disease-causing agents presence as a risk factor for susceptible populations (e.g., seizing and destroying contaminated foods or temporarily barring an infected person from preparing or serving food). In practice, however, control measures might be appropriate or warranted at any step in the sequence. Also known as rVSV-ZEBOV or rVSVG-ZEBOV-GP vaccine. This chapter has examined essential factors epidemiologists and other public health officials must consider when making decisions about selecting and implementing public health interventions during epidemiologic field investigations.

Among certain sectorsfor example, the legal profession, private enterprise, and even regulatory agenciesacceptance of epidemiologic conclusions has been slower, in part because of the nature of causation in epidemiology: epidemiologic evidence establishes associations, not hard, irrefutable proof.

The MVA-BN-Filo component of the regimen is a multivalent vaccine based on modified vaccinia Ankara (MVA) vector expressing EBOV, Sudan virus, and Marburg virus glycoproteins and Tai Forest virus nucleoprotein, and is designed to provide immunity to the Sudan ebolavirus, Zaire ebolavirus, Tai Forest ebolavirus, and the Marburg virus. For example, in a suspected restaurant-associated foodborne illness outbreak, restaurant patrons, the public, owners and management, media, attorneys, and public health officials are each likely to have a different threshold for judging the degree of association between eating food from the restaurant and illness.
