It is also recommended for healthcare personnel involved in the care and transport of patients with suspected or confirmed Ebola virus infection at special pathogens treatment centers, and people who work in Laboratory Response Network facilities that handle specimens that might contain replication-competent Ebola virus(Zaire ebolavirus) in the US. The extent to which causal criteria have been established.

Emphasis of the primary prevention is, besides a sufficient calcium intake, to omit risk factors; with secondary prevention the use of medical treatments such as estrogens/gestagens, bisphosphonates, and recently also SERMs is applied. "Secondary prevention is [the] set of measures available to individuals and communities for the early detection and prompt intervention to control disease and minimize disability, e.g., by the use of screening programs."

Another approach to classificationas universal, selective, or indicated preventive interventionsrelates to who receives the intervention. Public health officials who have responsibility and legal authority for making decisions about interventions should consider certain key principles: selecting the appropriate intervention, facilitating implementation of the intervention, and assessing the effectiveness of the intervention (Box 11.1). Three broad categories of determinants of human behavior will be discussed in this study session and you will have an opportunity to learn about the influence of these factors in determining human behavior. 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.
